I took my car to mb dealership three times for the check enegine light over a six month period each time they error they said was a kick down cable and that it needed to be replaced so they first time we replaced it and then one month later the check enegine light comes on again and the say the same error code kick down cable needs to be adjusted so they adjust then again the check enegine light comes on meanwhile we are driving the car with out any problems. Now the check enegine light is on again they say it is the same kick down cable on tuesday now thursday comes and they say we need a brand new transmission due to internal errors. Im not sure if all along they were telling me they wrong thing all along or if the transmission really went out. Please help! mb dealer wants 7500 parts and labor for a new transmission!

 

Are you able to recall when the CEL came on? Was it by any chance the same each time. e.g. Heavy acceleration or similar.

If the car is driving fine and the gear change quality is fine I would wait and see what happens before changing the trans. The CEL signals that emmission levels are being exceeded and of course this could be because the trans is not responding as required by the engine under certain conditions although this is not apparent to the driver

So what is the code number that is being stored. P0XXX?

Mileage?
