2004 c230 kompressor slips out of gear when driveing just accelerates I have to pull over then it resets when I put in park or just resets itself

this is an Automatic transmission? check your transmission oil, probably low or burnt.

Electronic trans shifter is defective loose connection with trans fail safe mode is neutral it needs to be property diagnosed by MB and replaced and programedw

does this one have the famous "vacuum modulator" which GM so confusingly named?

not sure do not know enough about the car ? bought the car new in 2004has 150k and always been serviced just started happening. Thanks

got to be the fluid. Been doing anything unusual, like towing or mountain climbing with it? just check to see that is red and between the hash marks when you check the dipstick. Something has changed recently and I'm thinking that perhaps you've got a small transmission leak leading to bad performance.

no towing or mountain climbing with it but will see if the fluid is low the benz dealer said the car does not need service on transmission for this model ? I guess it is a sealed transmission I dont know enough about it. Thanks

unfortunate of them to do that to us. My MINI also has a "pemenently sealed" CVT transmission that needs oil 'cause a main bearing leak---but alas have no way of adding to this extremely pricey fluid- 2004 till now...yeah, probably 100,000 or more miles on it. 'bout time you bit the bullet and took it in, as there isn't much we can do with 'permanently sealed'...I guess if you got under your car and found the plug, you could see if there was any fluid left in there...I guess.

Thanks for your help will take it in. Thanks again
