Hey guys & gals!

My S550 trans is shifting harder than usual after a transmission fluid flush/change. Anyone having similar problems? Any input would be appreciated

S550 FACELIFT 4Matic

Did you check the fluid level?

year and mileage?

Who did the "Flush/Change?" Do you KNOW that they used the right fluid to refill? They give it a fresh filter? If done at Joe Blow's corner garage do they have a dipstick to accurately measure trans oil level?

FWIW.... My car consistently shifts more smoothly after I give it fresh ATF.

Sounds like not enough transmission fluid.
