hey guys,
so my car is at 45k, a c350 2009.. recently when i push my car up to 40mph and slow down to 30mph... i feel a rough gear change.. (feels like a push).. I just changed my transmission fluid by the dealership the other day, and I still can feel my car doing the same thing. i'm not too sure what can cause this? i guess i gotta take it back to the dealer and see if they can check it out? STILL have 5,000 more miles b4 my warranty is over...

Any suggestion would be greatly appreciated guys!

There are a lot of trans solenoid valves that coud have issues w/o giving an error code.

Did you try to duplicate the shift in manual mode?

Did dealer change the Torque Converter oil too? (lesser issue)

thanks for the advice kevin.. I tried to reproduced the issue driving manual and it happens when i get my car up to 3000rpm and then up shift to another gear.. at 5th to 6th gear...

And... the dealer swears to me they did it right by replacing the fluids from the torque convertor and the pan.....

should i be too worried??

Make sure they did a proper change. Get them to ensure that you have the latest software flash on the TCU. Get them to reset all adaptions & ensure each change is within spec on Star.

thanks Glyn, the reason why i took it to the dealership to change my tranny fluid.. so if there is a bigger issue, they can't blame on me not doing it right.. I guess time to see the dealership again
