Ok so i just had hooked up to a mercedes benz scanner (believe it was coach scanner) to pull the transmission codes n it said no faults found. So no codes what so ever. So whats next? Could it be due to the atf i got from benz which is designed for newer 7spd auto transmission?
Pls let me know your thought.

it is not the fluid you got from mb. actually mb uses that fluid in all 722.6 trannies. the fluid you used is "the approved" fluid. i have the 236.14 fluid (same as yours) in one of my 722.6 and valvoline maxlife in the other 722.6 and both shift fine.
did this hard downshift start recently or did you experience it since you got the car? how hard of a shift do you mean, like a thump? when you are slowing down are you pressing on the brakes at all or just cruising?
