Title: PTU blew.. (confirmed PTU now)
Post by: TopherSho on August 28, 2018, 07:22:30 PM
Well, my luck continues and here's my new major breakdown. I was pulling out of a car wash and made a right-hand turn and it slipped a little bit .. I was not on it at all .. but it "slapped" when it regained traction  and I think it took out the casing or ripped out the shaft .. not sure which but there is transmission oil satans black smelly urine all the way down the block and it makes a really neat noise when you try to drive it.

Pictures will be later I hate posting pictures on this forum by my phone

ok its later.  just the oil mess a I am not working on this myself..

Sorry brother.  Look at the bright side.  You can build a bullet proof  tranny now.

Lol, I wish. I am not that mechanically inclined and they really don't make much in terms of aftermarket parts for the transmission for my 2010.

OMFG .. THE SMELL .. WTH???  Seriously do they take urine and feces from demons, dead cats, meth and  cram them into these units?

this is the most awful thing I've ever smelled and I've taken apart a supercharger when I was dumb..

Neat side note, as long as I drove straight I was able to safely get off the side of the road using the power of the rears to propel the vehicle...

How often do you have it flushed?  I do mine every 30k because my 2010 TC went bad at 112k.  It might be the PTU fluid also.

Na.  There was not time really to de-prep it... And the kit is in the trunk and the nozzle UNDER the rubber hotpipe.   If all he does is look at it on the lift and walk around  like I suspect he won't see anything.  All lines are sleeved, and I have no being mods ..

The only catch will be the TCU.. if it requires flashing the ECU to mate to the TCU I will have some 'splaining to do...

Sorry to hear Topher. I feel like you have had more bad times than good with this car.

And I think some of the programming for the TCU happens when you flash the ECU but I really don't know. I"m sure the dealer can do trans programming with the IDS software they use but I really don't know.

My now dinner addled brain thinks it is all IDS,  but that's based on a super old thread from the other SHOforum where a member who had access to IDS swapped in a pp unit and forced it to mate.

Guess well find out.. about to start a go fund me :P

Here is what PTU death looks like when it pools after stopping 2 blocks later.  (same pic,  but here as well for late thread skippers.)

Btw, the 2010 models do have a drain plug per se.

It's the port that they hook up to pressure check the system. I drain mine twice per year by means of this bolt.

If you need a pic, LMK.

Welp it is a dealer job so that's a gamble at this point.  My bet is re-maned which I think I like more... as to the plug, well dammit swore I read the 2010 was not accessible without heroic efforts.. If it is without dissembling the wheel/fender I am interested.

Post by: bpd1151 on August 28, 2018, 10:31:40 PM
The trans itself has a drain plug.

The PTU does NOT.

I just thumbed through more of the thread, and was confused as the title says, trans blew, but looks like discussion transitioned to the failure possibly being the PTU.

Not sure which one you've verified has failed.

A mighty vac pump with an extended tube is used to change my PTU fluid. Takes approx. 20min total. I'm thinking the dealer just didn't want to perform the service.

still not 100% sure .. the oil smelled so so so bad,  and it was a really sludgey black.  i will know by end of tomorrow when the pull off the cover.

when you change transmissions, generally all you need to do is update the solenoid body strategy in the PCM.  The TCM being the same as the Solenoid Body Assembly.  Now if you use a different type of transmission, you will have to update other parameters as well.  PP, non-PP, PI, etc.

And if it is the PTU ?
Title: Re: Tranny or PTU blew..
Post by: SHOdded on August 29, 2018, 01:34:50 AM
PTU is all mechanical, no electronic controls and no clutches on that guy.  But have not heard/read of any gearing differences, so couldn't say. They operate on similar principles, ie, intelligent AWD as Ford calls it, but physical unit sizes are different based on which model they are installed into.
Title: Re: Tranny or PTU blew..
Post by: SHOme on August 29, 2018, 07:05:43 AM
The PTU is significantly cheaper than a trans.  If you never changed the fluid it is likely that.  My PTU fluid in my 2014 had begun to thicken at 30k.  I change it every 20-25k now and use amsoil severe gear.  Got 104k on her and no issues yet.  I'm knocking on wood:)

Verdict is PTU,  a "inspector" for the warranty is coming to look at it in the next 48 hours.  My fingers are crossed a little bit.. HOPEFULLY the car will be on the lift still where nothing will show of the meth kit ..

PTU is best news it could be, they are relatively inexpensive all things considered.  I opted to not get extended warranty because replacing turbo's and PTU was less than I would pay on an extended coverage warranty. 

Crossing fingers for you that they cover it.  They are a known weak point regardless of tune, so hopefully be straightforward process.  From what I have read here they will hopefully replace it with the '13+ version so you can do flushes on your own moving forward.

maybe next time! Hopefully this is the last major repair.  if i can go without another big bang for a few years maybe e85 will be a little more wide spread and i can ditch the meth and go e30 instead.  then there will be no visible mods for them to zero in on.

So much for hoping they wouldn't find it. Despite how well hidden you believed it to be.

Problem is now, is that in the event of future repairs, is that it has been noticed, and is highly likely that it has been documented quite extensively in their database(s), so no matter which dealer you may choose to return to for future repair(s), this will follow you around like an albatross.

Be prepared for constant, uphill battles from this point forward. On nearly everything.

Good luck. :thumb:

Something is hideously wrong, I'm 99.9% sure they didn't test drive it .. it's not transferring power back or forth at all and it just trashes one tire the entire time and it's not throwing a code...

After a really large amount of wheel hop it goes into safety mode a d stops trying to put power to the fronts.

No weird noises though

Going back to stock now.. taking it back

Did a 3-1 downshift and it tore loose the FR hard enough spin it loose and  to up shift before getting back up to speed.  Seems stronger than before

HMM this morning it is doing the same thing.  need to log it i guess. 

It is like the tranny or PTU just gives up after about 3/4 of the TACH .. it just 'lets go' then only engages the rears.

THERE'S NO TEMP LOGIC IS THERE?  IE CUT POWER WHEN COLD?  that is the closest thing i can describe without a log.

There is temp logic that can cut power and throttle and all sorts of things but I think the front differential is an open type diff so usually there is only 1 dominate wheel. But the front is all mechanical I think so there is no way for it to cause excessive front wheel spin any more than normal. The diff is open and the PTU is gear/chain drive I thought....Are you sure you aren't just blowing off 1 front tire and not getting traction from the rear diff?

I will get a log to be sure .. but it starts good,  gets about half to 3/4 through the power band,  hops the wheel maybe one or two times then completely disengages the fronts until you stop and power it off and on. 

this morning it did not fully disengage,  but it would not upshift until it hit 4500 rpm in auto mode.

after i log it i will go back to stock and try to reproduce it again,  maybe i just did not try hard enough.   but to me,  as a seat of the pants diagnosis .. it seems to be cutting the power deliberately .. MAYBE when it is cold.   

in my 2 hour drive it was nearly perfect after it was hot.

maybe it is time to just rebuild the tune from scratch ? i do have new turbos, new ptu, new plugs, new boost solenoid...

EDIT: this has happened once before at the track a few years ago.  when i launched it got my foot stuck (boots) on the brake and did not launch until well past the stall limit on the TQ converter.  it was about 3000 rpm.. it hoped the wheel super bad and the fronts stopped working.  i coasted / drove slowly with the rears to the 'pull out' and it would not go back into gear.  power cycled it and it was fine.  this feels EXACTLY like that time.

Topher the fronts can't be disengaged...Something sounds weird...Bad wheel hop can cause stability control to shut things down.

hmmm it is the only way i can describe it... the fronts don't pull when it does it.  only the rears push lightly  .. Lamrith i think has had the same thing happen on a bad launch.

there is to much morning traffic so i will have to log it later.  then i am going back to stock.. i cant rip apart another ptu they wont cover it this early on.

Here is the data log   
got in and drove as soon as SCT was logging.  car still had a little temp but it was essentially cold.

drove to my corner,  a 45 mph street,  turned right started on to the road,  then floored it and gimmaced.

it started boosting but it pulled power started thrashing hard. 

once i let off the shifting continued to be 'bad' wont upshift correctly,  wont downshift correctly.  kept locking onto 1st and 2nd gear... because if i have it any gas the rpms would shoot to 4000-5000 rpm and accelerate hard enough to trigger the behavior again .

shut car off for 30 seconds. restarted all good now.  car is hot and idling ... will see if the issue still occurs. or if like last night  now its fine.

for the record.. it is pulling *much harder* than before or it has been broke for so long i did not notice the degradation.  i swear im a 12.4 car now as to what it was when it was 12.6... acceleration is SAVAGE. no tune changes,  just the PTU change.

Damn topher I don't know how you manage....when you hit ok you shouldn't be able to do anything with the car off...the device just won't do anything until you turn the ignition on

Oh it quite happily did the "downloading firmware part" .. after that it said 'done' and did not attempt a flash back up or in this case back to stock.  then it was .. done :P

For posterity : I put in the 2 bar,  got in and hit 'ok' to go to stock, I hit ok again and was not paying attention as the Ford console screen was on.. but the guages were not lit.  It did the download part and by that point I was afraid of bricking so I let it go,  the car console screen was 'on' but the car was not 'on' .. it finished the 'download/backup' and skipped straight to '"done turn key off'" .. after that return stock was no longer a option.

I think it was in accessory mode is all.

edit : have not heard back from SCT yet,  I will give them a call in about 10 ..

Would a compromised Torque converter cause an issue like this?

the STRAT was the same, no fashes just a battery disconnect.

I have no idea.  the tune log showed a tq error 7 as the initial error.  then it goes nuts.

OK we have update(s)

I'm glad i am a backup nut job.  they were able to recover the stock tune from mt .BEF backup files that i make EVERY SINGLE time AJP sent me a update.

The SCT lady who was very helpful did say that the device should not have been able to pull a bad file FROM the ECU to the SCT device. but also said in the same sentence that it may be possible if the car goes from running to accessory mode.. and you try it there.  I might have done  that in error as i was swapping back to the 2 bar before reverting to stock.

it is idling correctly and no wrench codes.  i will try to rev it after it idles for a while,  and then drive it if no codes pop up.

Heh .. I am not entirely sure what they considered dirty as I cleaned it no less than 4 weeks ago myself

As to the car now that I'm running fine on stock I can confirm that there is zero issues with the stock performance..


The only way I can get the behavior to occur now is to turn hard left or right and floor it, but that's always been the way these cars behave

EDIT :: i will wait on brads thoughts.  im leaning towards from scratch retuning it.  but its up to him.

Brad has built a fresh tune based off of the last good REV,  i will try it out. in a little bit.

I predict the issue will still occur,  I think it is the TQ converter as a random topher guess.

Topher few things I also saw. You hit the rev limiter every time on the shifts even though your shift points are lower than stock. When you see torque source 4 in the log that is rev. limit.

When you look at commanded gear is starts at 1 like it should then goes to 2 like it should then back to 1 even thouh you actually get to 3rd gear.

And when you look at vehicle speed it's the most jagged line I have ever seen in a log. It's like it's not commanding the correct gear or there is an electrical or sensor problem

It's odd. I'll attach a screen shot the way I view it.. RPM, commanded gear and vehicle speed.

I'm no trans expert but I've had cars with low fluid and they slip terribly and don't catch gear...Topher I fear for your car already...If it's slipping that bad I'm wondering about the clutches too.

The ECU calculates gear sometimes by what's called N/V ratio..I forget what that stands for exactly ...Engine speed over vehicle speed...And it gets used someway but the car won't shift correctly...So if it's slipping engine speed may be out of whack for the vehicle speed and also if the vehicle speed isn't being reported correctly as seen in that pic, then things could be all out of whack.

Spit balling here also.

Here is a screen shot of a WOT pull showing what vehicle speed increase SHOULD look like....You can even see a little spinning on the 1-2 shift....And you see the commanded gear lines increase as they should through the gears.

Topher, your's is jagged like nothing I've seen.

Post by: TopherSho on September 13, 2018, 02:43:43 AM
ok in total I added 1 quart, and a tiny bit more.. like a 1/8th more.  The ball is now covered right up to but NOT on the cable part as i remember doing it when i initially had the other guys tune. 

I will test it dead cold in the morning .. but i am 99% confident it is now solved.

If the issue persists, you can try logging more trans related pids, that will show shift lag, tc slippage, etc.  Good luck with the testing tomorrow/today!

Might also be looking at a TSS/OSS sensor issue (and MAYBE a TRS issue) now/down the road.

Will do.

Test went 90% good.  10% suspicious.

From a dead cold start from last night i hard accelerated from a left hand turn to my Dairymart for Diet Mt.Dew, no issue.   When i left i gave it the hard boot again,  no  issue.

at a stop light i power braked it to about 2200 rpm and let go and it ran great but it seemed to skip either at shift or before s*** i honestly could not tell.  that made me suspicious so i did it again on a side road.

it did hiccup around 4000 rpm.. but it was NOTHING like what is has been doing.  i did it a few more times but now it is hot and not doing any of the behaviors.

Next test :
-turn meth onset down (up) a quarter turn, its cold for meth out here now,  remove chances of wet/misting the plug
-from a dead cold sit power brake to 2000 rpm and try again.

Tophs ...

have not yet check it.. daughter is still awake ;) .. been driving it .. verdict is still out under high tuned load.  i have launched a few times in manual mode and not seen the issue.  but it is all still inconclusive to me.

How much oil is everyone overfilling in their tranny?  right now the metal slug\ball is just perfectly covered.. what is the 'safe' limited to fill to?
Im approx a pint over with zero Shudder issues

What does that look like on the stick and slug? thnx in advance ..

About 1/8th of an inch over the hash marks on the stick.

And Topher you should never do all your testing when the fluids aren't warmed up to operating temps.

I cringed for your drivetrain when I read that you did that. Geez.

As an aside,  its not like i'm going out every day and hard running it from start and go 30 seconds later.  I was only doing this for this issue to test the viscosity portion of the equation since fluid thickness with low fluid could explain hot = ok and cold =bad behavior.

I let the car warm up 4+ minutes every time i drive it in the morning using the remote start.   Because as much as people hate that ..  VW cars, my bosses AMG C63, and Audi's all have cold running power limits and i feel that if they do it .. so should i :P.

My 2010 had stuttering issues on shifts which is well documented here... specifically with Unleashed and LMS... the car would go to shift under WOT and it would stutter before catching the gear.. sometimes it wouldnt catch gear until very late if I pushed through it. Topping off a pint over full helped a lot but it never fully solved the issue..never was able to figure it out..

Hammering it while turning almost always produced the issue.. think trying to swing the rear end around into a drift.. it just flat out wouldnt catch gear and it wasn't the advancetrac kicking in, it was a mechanical issue.

I hope you are able to solve it, it was a major PIA at the track.. some runs would go flawlessly and others I would have to back out halfway down the track.. it would do it most on the 1st to 2nd, but occasionally on other gears..

That 2010 had been beat to death...so I am SURE that played a factor.

DAMN I forgot... I was able to cure 90% of it by doing 3 x drain and fills with motorcraft LV trans fluid... Perhaps they didn't put the correct fluid in the car? I had a my trusted shop flush mine (I know.. never do that) and put an OEE in there that caused all kinds of problems...

Letting the car warm up for 4+ minutes only warms up the engine, not the transmission.  Keep an eye on trans temps to see how long they take to reach operating temperature under your driving conditions.

So true.

I see it on my trans temp gauge that it routinely takes twice as long, if not longer, for the trans fluid to get up to operating temps.

Annoying when one's just starting out and wants to have fun. But due diligence, coupled with patience, is tantamount to longevity of the components.

Mine's a great example of that.

Topher...... continued successes with not only resolution, but also enjoying your whip to its' fullest! :thumb:

Sounds similar,  it is frustrating as the issue did not occur until the PTU replacement.  I am still mapping it out.. I am less inclined to think it is the TQ converter now as running in manual mode i can load the crap out of it and not see the issue in any other gear. 

If the Fluid is at the right level after testing hot today and the behavior is dead cold only i may just resolve to accept it as is for now until it breaks.  I dont race it cold so i simply may have never seen the cold stutter before.

noted.  but it is not dead cold though?

It takes roughly 30 minutes before the TRANS is FULLY Warm up IIRC!  Z

Just a sample of trans temp behavior.  It takes a while.  And with the bypass valve opening well before operating temp, higher speed driving will slow temp rise further (passive cooling).

After a hot drive to and from my work meeting I checked the fluid in the transmission after adding one quart and one eighth yesterday, it still needed more to not be in the fill zone and to a
Be above the hash by 1/8.

That makes 1 fully and about 1/3-to 1/2 I put in it.

Fixed. runs EXACTLY like it used to now.

I'm taking the video of me checking the fluid and finding it almost off the stick to the dealership gm.  i have no real expectations,  but i plan on letting them know of how awful it has been dealing with them and their past and current mistakes, NO TEST DRIVE and now i get to drive to another shop for my needs. 

These guys just suck.  I gave them 4 opportunities ... the failed every time.

Glad to hear all is whole/complete once again.

The irony of how touchy this car is to even slightly low level(s) of fluid(s) is awkward.

Seems it likes a touch more of everything across the board with any/all fluids.

Particularly in the cases of the tranny and coolant.

Meh. I digress. Sucks you have to source yet another new shop for future repairs, but at least it sounds like you escaped this craptastic experience virtually unscathed.

Enjoy a weekend of spirited fun.

Thanks BPD1151

The GM listened and has added text to my car record that the incident with the tranny fluid could have 'possibly' damaged it.  They have agreed to take a sample of the fluid for testing..  obviously THEY will do it and THEY will have test run themselves .. So how much i trust this i do not know.  But when i mentioned if it fails in the next few months they said they'd replace it.  I asked for a Tranny shop to do it as my experiences there have been negative and they declined to pay for another shop to do it citing them not covering third party repairs.. I get it .  I don't like it.

I am keeping my exceptions super low,  like dead gopher low.  But we will see.

Some things to keep in mind
Just sharing an opposing view, I fully understand your frustration.  You have had a rough go Topher, and way more patience than I have.  I would have dumped that car months ago, been there done that with the car before this.  I LOVED my STS-V, but the constant issues drove me crazy, so I traded it in on the SHO.  I hope this is the last of the issues for you, I want to see you in the 12's.

Would agree *if* I had detuned it. It was still full tuned.  50% throttle cold caused the issue. 

As to wot testing.. it wasn't needed to reproduce just getting on the freeway dropped it out and back into gear. 

As for 12's ;) I have been running 12.6# since last September and it is a hoot pushing this 4650lb sled with a paltry 2.77 ratio.

I totally get the POV but it was evident there was a issue without hammering it.

Since they serviced and flushed etc your Trans.

What is the fluid level at ?

Isnt the recommendation here to slightly over fill these units?

BTW,  I forgot to thank you properly sir. your reminder about the slight overfill lead me to find the 1.25 missing quarts of Trans oil.  TOTALLY forgot I did the overfill with the previous tuner.

thank you Sir!

Did you have any sounds before it blew? I'm trying to determine where my noise is coming from. I think I saw that @ajpturbo said that it's chain driven. It very much sounds like it could he a chain slapping. It mostly does it when it's cold, making a left turn under acceleration.

Not a PEEP ... I pulled out of the car wash,  was not even past 20% throttle, slap! followed by Bang! bang! bang! and that AWFUL smell ...  I just read your post,  i also think shaft.  We have had two other members loose their shafts on 13's+
