Normally when you let go of gas to go in reverse or forward at low speeds(in a parking lot for example), our cars have enough torque to move the car forward at a good speed.

Compared to a c280 or c230 its a lot stronger pull but lately my car has been a little different. It still pulls consistantly but it seems noticeable weaker and it feels like its not as immediate. There are no jerks or anything but im a little worried because I know this is a potential start of tranny issues.

I had my transmission serviced when I did my engine swap a few months ago and it all looked fine in there.

Am I freaking out over nothing or should I do something.....and what?

Is that happened after 5.4l swapped..?, is it stronger with previous 4.3l..??

ZAYED,,

Yea it just feels like the pull was stronger with the 4.3

Do you remember, it happened before or after flush ECU..?

That has nothing, ZERO to do with a transmission issue or start of transmission issue or anything related to transmission.


You can change your idle speed with a Mercedes tester, this is what will have a large effect on the condition you speak of. If you raise idle all the way you'll find you have to push the brake pretty hard to keep the car still at stop lights. Personally I'd like as little idle rollaway speed as possible. If you really want it to pull away more at idle bring it to your dealer have them increase your in-gear idle speed.

Also want to make sure your chassis is good, if your wheel bearings are rough, brakes dragging or parking brake too tight, this could have any effect. These are all very doubtful mostly hypothetical.

if he raise with higher idle, while keeping the foot on brake, pads will wear faster, yeah?

Thanks for input. My brother had the same thing happen before his tranny went out on his s500.

Im releaved to know this isnt the case

I think something related to the RPM & gear tq/c., you can raise the D & R speed through STAR/SDS...!

Not if the vehicle is stopped!!!!

if stick is in D at red-light car will pull forward in D, keeping your foot on brake will wear pads, i always put in N at stoplight if it's a long queue

I think what our brother is saying is that if the car is not rolling, then the rotors are not rubbing against the pads = no wear occurring

DRBC43AMG

Correct!
