Hi All, first time poster but have read the w202 common issues up and down
My Trans is the 722.6 model (5 Speed auto Electronic), it shifts VERY rough (jolts the car) especially first thing in the morning and especially from gear 1 - 2 and 2 - 3.
It also doesnt gear down correctly - for example if im doing 60km/h and put my foot to the floor it doesnt gear down it just very slowly builds up speed ( i have been gearing down manually as a work around)
Last thing it splutters and backfires in the morning if you take off onto a busy street and almost comes to a complete stop whilst doing this, and sounds like its coming from rear exhaust.
AND this morning i was driving on the freeway and for no apparent reason the engine turned off and all the lights on the dash lit up, after this i pulled to the side and was able to start it up again.. but why ? the car wasnt even hot. I did have the stereo up loud with the heater going.. but nothing out of the ordinary
A lot of fixes out there suggest looking at the vaccuum module and checking pressure but i dont think mine is the Vac operated tranny?
Any ideas what this might be? i have done a trans service, spayed the MAF sensor with MAF cleaner, ignition coils apparently tested and ok.. oh and replaced fuel filter
- Can anyone shed some light on these issues? - James
