1997 Mercedes-Benz C230 Q&A
1997 Mercedes-Benz C230 Question: Hard shift cluck 2rd gear sometimes. Shift gear valve assembly fault. 140K miles
Dealer: rough shift only on 3 to 2 downshift. Found transmission fluid dark. "performed short test, found stored code for selector lever is implausible, communication with engine module, and reverse/park lock solenoid fault" <- don't understand this. Normally would recommend a valve body, but mileage is high. Not confident will fix shift issue without cause clutches to slip. Best replace entire transmission. - jgy2001
A flush and seafoam treatment couldn't hurt. $150.00 is better than $4,000 if it works. - Hal...
