DCT 5th 6th 7th gear very aggressive jerk/stall feeling

Ahmedm1 · 10-14-2020, 11:51 AM

I have a 2018 DCT comp f80. When I am in D1 in any mode 5th 6th and 7th gear cruising in the city the car feels like it is going to stall. Especially in 5th gear. Can it be the spark plugs, injectors, or transmission?

My 2015 dct m4 do same, on engine side i changed all, injectors, coils, spark plugs, intake, chargepipes no ones help. If i press a little more gas car run very smooth. No clutch slip, my car run 11.3s 402m on dragy. No errors on ista, new oil and filters at gearbox.
I ended with xhp dct remap and increasing a little bit gear changes on 5,6 and 7. Gearbox adaptation or any other reset not help, i tried. Please share if you found the problem, for the moment i suspect gearbox need replacement.
