Good morning world!! Yes, Liqui Moly Top Tec ATF 1800 can be used in the ZF6HP26 transmission provided the container lists Shell M-1375.4 / ZF 6HP26 compatibility. That is the important specification for this transmission. Let me know if you need anything else.

Good morning,I have changed and I replaced one of the solonoid (black colour solonoid) and it is a used solonoid.The brand name is (bosh).I bought it from someone who fix BMW cars.
However,when I drive the car it changes gear 1,2,3, 4 times rough but not smooth.When the car stops and to move again it does not change gear again but in order for it to change gear again, I would have to turn off the vehicle and restart it again for it to change gear.Do you think the car needs to programme or reset to fix the problem?What do you think?
