If you really think about how many 6f55's there are, there really arent that many failures.did you get the flex new?...i say get the rebuild done...get some good fluid in there and good trans tuning from the popular tuners out there and you will be fine

No, i bought it used at 100k miles. The engine threw a rod 2 days after i bought it. Its had a few problems. Now with new engine and rebuilt trans im hoping for a fresh start.

Good lord thats a rough life

Youre telling me 😔😳

They did say it's not cheap for the parts. Haven't looked into it myself as these transmissions do seem to be pretty strong.

Good luck on the rebuild.

Thank you much! And yea. Ill look into upgrades for the trans when i hit the 500hp range. Does anyone know the horsepower limit for these 6f55s?

Yes.

I was told by the engineer's who developed the 3.5 SHO Ecoboost platform, way back in 2011 when I had my 1st (of several) tours of the CAP (Chicago Assembly Plant) that Ford did not experience trans failures until "around the 720 (crank hp) mark".

Now I was never told the specifics of what broke, and nor did I ask, but that's the magical number to avoid.

They say the flex will be done tomorrow. So this including time when car was in shop waiting on new engine totals a nice 6 weeks without my flex and only owning it for 3 months!! I guess i can say i fell in love with her at first sight and refused to give up! Lol. Im just hoping that the shuddering problem is all gone. It better be after over $2k worth of work. Beyond excited though to have my baby back.

If tuned:  Take note of the strategy code as you return to stock (including 3 bar MAP to 2 bar MAP) -> take car in & get it serviced -> check strategy code when you get car back -> have tuner update your tune if the strategy code has changed -> reload tune -> ENJOY!

Got my flex back and problem solved!! Shifting as smooth as slicing butter. No stutter/shudder/hesitation whatso ever. Money well spent 👍👍 Just glad that nightmare is finally over.
