722.9 Transmission shifting problem
The transmission is smooth on every gear changes, even from 1 to 2 and from 2 to 1.
When I am driving at 7th gear (speed 60) then braking, transmission downshifts to 3rd, 4th or 5th (speed can be from 25 to 40) normally like suppose to be. When accelerating to the same speed (60) and transmission sometimes forgetting to upshift to the right gear (can stay on 3rd, 4th, 5th) with high RPM. Doesn't matter if it is sport or comfort mode. I am using pedals to change the gear and it helps. It is not always happens, maybe two times a day, more often after harder braking.
I have DAS, No fault codes present...
Maybe I need to reset the adaptation? But dealer recommends to do reset only after repair.
Please help. Thank you!
