Independent Mercedes Shop put in wrong atf in Mercedes 7spd

[Rp1990]

2011 e350 rwd A89 code (reduced friction)

The reason I’m making this thread is because that after the shop change the atf fluid,Now I can feel the vibration when it cold while I’m changing the gears P>N>D OR >R.

After driving for 1 min or so (while fluids getting when up ) no vibration is there.

Does this have anything to do with putting the wrong atf?

They put in top tech 1800 instead of putting the
car called for top tech 1900 in the car.

Sure, they put basically a dex VI fluid in it. You need a MB 236.15 spec fluid not the red 236.12/14 fluid. MB is specific about using the blue 236.15. They owe you a complete flush with the correct fluid. Find another garage.

Hello,
It still in the car, so I’m taking it back on Wednesday by having good sam tow truck take it back to his shop. The only time I drove the car was after picking up the car from the shop and drove it maybe 60 miles back home.

I just don’t understand why it would vibrate then after warm up it disappear.
I’m just confused why would different fluids cause that?

The fluid is thinner when its warm. The 236.15 is a totally different fluid and much thinner. This is the 236.15 spec (blue) These are Motul fluids for these specs, look at the difference in viscosity.

This is what they used 236.12/14
