Those of you with repaired 2020 F250 10-speed transmissions...
My 2020 Lariat SD 7.3L/10spd with 35K miles is 10 weeks at the dealer waiting on parts to fix the "leaps forward shifting from Park/hard-upshifts/sometimes won't downshift/hunts 4th gear/7th gear limp mode" transmission problem that thousands of people have had.
My question for those of you who may have made it through to the other side and have been repaired - did the fixes work or are you still getting bad tranny behavior and/or slinging codes? Just trying to figure whether I keep this thing after the repair or drive it to a dealership somewhere and trade it for a '22. Or a Toyota Tundra HD....(god I hope not).
I have exactly the truck I want - I just need it to be reliable.
Thanks!

My 21' 7.3 Tremor developed a intermittent shift problem where it started slamming into random gears in heavy traffic with the slightest acceleration. My dealer easily duplicated the issue and did a 're-flash' and asked me to drive for a few days. It may have helped some, but in no way was it a fix. When I returned the truck the mechanic explained there is a seal that is allowing pressure to by-pass it causing the hard shifts. I'm sure that was a layman's explanation, but the truck is now working excellent, couldn't be happier with its performance.

MY 2020 was not within the recall but basically got stuck in 7th gear. Dealer checked TCM and then found metal shavings in the transmission at 16,000 miles. 9 weeks at my dealer and they replaced the entire transmission. Better than before so far.

I just recently bought my 21 with not quite 59k miles and it would downshift hard in to 3rd often. Brought it back in and pinpoint tests passed so they reprogrammed the TCM. That worked for about 150 miles. Brough it in again and this time it failed pinpoint tests indicating a bad TCM which they replaced. It's since been much better but not 100%. It's done a hard clunky downshift into 3rd about 3 times in another 150 miles. Not frequently enough that I think the dealer would be able to reproduce it. I've got about 800 miles to 60k now so I'm hoping it either acts up hard again inside of that where I'll lean on the dealer to replace it, or chills out and behaves for 100k.

My 21 with the 7.3/4.30 was doing it almost from day 1. Had it in for a new valve body earlier this year, and that seemed to have fixed it for a while. Problems are back now, they told me last time that the next step would be a whole new unit. Going to take them up on it this winter.
