Mine was a really hard down shift from 2nd to first in situation where I was doing a slow creep to a stop like pulling into something but trying to slowly get a foot or two closer. I noticed it helped a lot

mine does both shift down and up, i heard that can be prevented if you ask dealer to update sofware.

mine was changed at 85k - the shop described it as not burned, but definitely used fluid. (i described this in previous thread). noticed smoother operation of trans and shifts were more gentle. my car *might* not be driven as hard as some of yours, though! :-) a worthwhile expenditure of $225. dealer was quoting $369 for same job. shop around.

so wtf now my mechanic tells me this can only be done by the dealer to people that have 7speed tranny... someone please confirm this.

Hi mate,

The 7G-Tronic gearbox needs to be drained in stages. The torque convertor also needs to be drained.
The car also has to be in the air and level.

It is not a neccessarily a straight-forward job to do, which is why your mechanic has probably recommended an MB dealer.

Where did you go? I'm sure my shop could take care of it for you.

thank you


Find out for me if they can actually do it for my car, i dont want to end up ****ing my car up.
my mechanic told me you need a special machine that MB only has that put new fluid in with that machine which calculates the amount, because supposedly the speed is very very oil level sensitive.

If he can't do it, I don't think he would try. I will find out for you.
