I have an 02 clk55
Battery is good
Tranny was just flushed, New filter and gasket and also replaced the connector pin.

I had the transmission flushed, connector pin replaced and I got the car back from the auto shop, at first I thought it was a fluid issue however there are no leaks.
Day 1 after getting the car from the shop I had no problems at all. Check engine light was on however the car corrected itself by the next morning I was driving and the problem began again
I drive and shortly after there is either no power to the wheels or the car will stay in 2nd gear and rev all the way to 4000 without shifting
eventually (less than a mile or so) when I stop the car will no longer move and I have to turn the car off and wait several minutes to even move again. I don't know where to go from here. I dropped the car off at the same shop and they are thinking that I may need a whole new tranny. I am hoping they are wrong and would really like some feedback as to what the issue was with other peoples cars.


Please Help....

I would dump the codes. Many transmission codes require a star box to be cleared, so you may have to make a trip to the dealer. If the car was running fine before the transmission fluid change, then something may have gone south during the service. These transmissions go into limp home mode rather than allowing something minor to devour them. Hopefully the mechanic who did the service did something wrong that only requires an inexpensive fix, like $100 in diagnostic fees and a second $350 fluid change. Overfill or underfill, either one can cause the box to go into limp home mode. AND fluid levels must be checked at temperature.

I hope that helps
