[Dima_RUS_M340iX]

Hello.

I own a car M340iX. Mileage 4.700km.

I was worried about the quality of the gear shift in quiet mode D.
Shocks from 1 to 2 gears, as well as during smooth braking, shocks were felt.
I have positive experience in replacing the oil in the box 8hp50 F30.

At the moment, has made a partial change of oil 5l. Oil was poured by LIQUI MOLY Top Tec ATF 1800.
The effect is amazing. Almost all the symptoms are gone.
In the near future I’ll try to completely change the oil, pour 5 liters twice.

Maybe someone will be interested in this thread. Thanks.
