I wonder if I should go back to the dealership for this one. I've had a few rebuilds already for harsh shifting from 4th to 5th. It keeps coming back.
I would! Especially if it easy to replicate the issue. Get er done before warranty is up.
I've still got a year and a half on mile-train. And 0 confidence that Ford has actually fixed the issue instead of bandaging it. But I'll probably give the good dealership a call this week.
I have a similar issue with a very rough shift from 4 to 5 in all of the sport/track modes, but it only happens on the track after it heats up (road course). Sometimes it’s so harsh it feels like the drive shaft is going to fall out. Dealership is unwilling to investigate further because they can’t replicate it on public roads. They flashed the TCM, which helped with all of the other rough shifting, but not the 4 to 5. It’s such an annoyance that I’ve considered selling it.
My rough shift seems to happen whenever you floor it. It just feels worse in sport/track mode.
Did they change any parts out or just update the software?
Both. They rebuilt the valve body and updated the TSB. I still have to drive around a bit more for the relearn, but it still seems like I might have the issues. We'll see.
Ok thx for info.
