10r80 Poor Shifting/Missed Gears
Posted: Thu Nov 03, 2022 9:34 pm
At 16k km Ford replaced the transmission in my 2021 Bi-Turbo 10-speed Wildtrak. It developed a whine on overrun and suffered from erratic shifting etc.
When the new transmission went in I couldn’t believe how much better it was. Then, just last week the family and I were travelling home from Lennox Head to Sydney and about an hour from home cruising on the highway the ute started violently jerking between gears (5th to 10th) and wouldn’t accelerate at highway speed. It was totally messed up with trucks barreling past at over 100kph and the kids were freaking. Slowing down and easing it home helped but Trans temp was around 118°C for an hour or so (I wasn’t towing and had no more than 100kg in the tub). Since that episode last Monday the gearbox has been terrible again with hard shifting, missed gear shifts and at times violent shifts. We have literally only done 6000km since the new gearbox went in.
It went into my dealer for investigation today but of course they said nothing was wrong nor could they find a fault code and fluid looks like the day it went in. That’s even after I shared videos and screenshots of my OBDApp readout.
Are the 10r80 gearboxes really that terrible or have I been really unlucky and got a second lemon transmission which is on its way for premature failure?
The dealer did the whole TCM PCM reset but it’s no better and I didn’t expect to be either. It’s a real bummer but I’m wondering if anyone else has suffered terrible shifting from their 10r80 and what they’ve done to help make it more “liveable”.
Cheers!
