I've read alot about this error today.. on here and other forums.. Just bought a 2005 C230 this weekend from a dealer. only 33 thousand miles.. not under warranty.. got it back home and now 3 times my tranny has slipped.. last time it did it, it threw a check engine light.. Diagnosed as P0730. So i started reading about it..

Could be
air sensor
spring in valve
oil in connector
Trans control unit
low trans oil
dirty oil

So i've read a bunch about this, but haven't really found anything in regards to what has fixed the issue for people.. Can anyone who knows or has dealt with this let me know what usually fixes this issue. I just bought this car and im looking for any advice.. Is this going to have to be a new trans replacement.. :eek:
