The car started jerking while pressing on gas at low speed after changing the transmission fluid. Is there any thing I might have done while changing the fluid? I have watched a few videos on how to and I thought I did it the same way...

Which transmission do you have and which fluid did you service it with? from my understanding there's a process to transmission fluid changes

To add, did you follow proper procedure on how to fill the transmission?

Is the car jerking or shifting hard, such as a hard gear change from 2nd to 3rd at low speeds?

I thought I followed a few videos I watched

jerking that is which happens before the gear shift

I do not know the transmission but the car is 2012 c250 turbo 1.8L

Not sure if that is approved for your transmission. You need to confirm absolutely that fluid is approved or you may have effed up your transmission. Here's a source for the correct stuff.

From what I just read from valvoline website https://www.valvoline.com/en/maxlife-multi-vehicle-atf/ and the spec sheets https://sharena21.springcm.com/Publi...0-ac162d889bd3 it includes both 236.14 and 236.15 - I'm not sure how that works since from my understanding those two transmission fluid specification are not cross compatible.

I'm not sure which transmission you have, you could possible call a dealership parts department and they can determine your fluid specification based off of your vin number

Even though Amazon says it "fits", I would independently verify this. It needs to meet specification MB-236.15 and/or referred to as ATF-134FE. I do not see that on the label.




I also don't trust the Valvoline site because it says that Max Life stuff is 236.14 and 236.15 compatible, but you cannot mix 236.14 and 236.15. Maybe if you somehow could completely flush out all the old fluid (to include the torque converter and transmission cooler), using only the Valvoline stuff might work, but why take that risk.

Bottom line: Get the right stuff! Don't try to save a few extra bucks on a service that you do every couple of years.

also what's the mileage on your car?

122K

I gotta service the transmission fluid every 2 years?

I know there are some on this forum that say Valvoline Max Life is okay. Valvoline claims that Max Life works in just about everything. But its not on the BeVo. What is on the BeVo are the approved fluids Valvoline ATF Pro 236.14 and 236.15. Even in the Valvoline brand, the two fluids are separate.

Every Mercedes C-Class W204 built after June 21, 2010 with a 7 speed automatic has transmission 722.9 7G Tronic Plus (code A89) and requires a fluid meeting specification 236.15. You have a 2012, so that should include your car.

Whether Valvoline’s claims are valid is up to the user to determine. But all these manufacturers design the transmission fluid to have specific friction and viscosity characteristics to perform well with the clutch material used while providing the lubrication needed. I personally suspect that an Allison sitting between a Cummins highway diesel and an 80,000 pound load has very different requirements from a 200 HP I-4 pulling a 3500 pound sedan.

Is that a question?

yes, my understanding was every 60k miles so

would this work?

Yes as Fuchs has aquired Pentosin and Fuchs was one of the Co developers of 236.15 .

Can't understand how the Valvoline is both specs as the latter is thinner viscosity .

Yes. That’s as good as it gets.

Marktree, have you confirmed if that’s a 7G-tronic or 7G-tronic plus transmission? I’d verify that first if before committing on the fluid.

I was relaying information in this sticky:

https://mbworld.org/forums/c-class-w...-imminent.html

If there is potential for C250s to have the 7G-tronic as late as 2012, then Marktee should check his data card.

Great idea. The data card info can be found here: https://www.lastvin.com/

You have a 7G-Tronic Plus and need spec 236.15 transmission fluid.

Does it mean that the one I ordered from FCP work?? 134FE??
