Title: Not holding power in 1st gear in the cold?
Post by: TopherSho on December 03, 2019, 11:23:49 AM
I have noticed that even when driven 30 minutes the tranny is having issues holding power in 1st gear.   I am about to check the tranny oil ... but has anyone else had this occur after being 'stable' ?

Whats everyone's go to for tranny oil ? for cold weather ?

I run Mercon LV year round, but what are you considering "Cold" weather?

And when you say problems holding power, is TSC kicking in or it is popping out of gear?

feels like it is ''low on fluid'' and letting go of the gear.  i am working so i cant check right now..  the only thing i can think of is i might have to much oil,  and it is cold enough to cause it to not flow as well as it needed this summer when it was fine. 

cold btw is 22f

-5 and I have started to notice in full traction off and drive it seems to shift sooner but will hold longer in sport.
I haven't looked at rpms but just by feel and sound but didn't think much of it.

Yeah,  The oil is the same spot on the stick,  and it is 30f warmer today and I am having no issues .. when the engine swap occurred I am willing to bet this is NOT the previous oil brand (castrol LV+) I had in the unit and it is reacting different than the Castrol did in the colder climates. 

I will drop 2 cups and retest..

Why wasn't Ford Mercon LV put in the car?

It is a guess on my part that the mechanic used some other LV+ compatible brand .. Ideally I should drop in Redline .. maybe i will spring for it this time.

be an easy and relatively inexpensive check. That's assuming they even used an LV at all.

dropped half a quart out and its better,  still happens when the steering wheel is turned more than 10 degrees or so... tested with the hand held and am seeing Torque source 2 and 15. 

It is frustrating a bit that in the summer i did not see this issue... I pinged BRAD / AJPturbo to see what he thinks.   in the mean time has anyone else seen colder temps trigger Torque source 2 and 15 more frequently ?

Hmm wonder if AdvanceTrac and EPAS are conspiring to hold you back.  Any difference in steering feel, or any pending codes?

Did you recently change the starter! I hope the dealer did not screw up with starter/Ground ..Not quite certain if its related but some ford models have intermittent Ground issues to the Trans! Dunno. Z

Aw man now you are taking me back to my G35 days .. I had weird shift issues after an Orsis tune+nismo cams and a head grind until I cabled the trans ground to the frame,  and cabled the two front grounds to a 8-guage wire I soldered to the the left frame and right frame ..

Naw in this case my good man it is good old 1st gear makes to much power.   Brad is going to send me a updated tune to test.

Maybe an adjustment to Torque management! Fingers crossed. Z

After a bump in tune revision it is much better.. still testing.  May have been old tune issues
