Mercedes Repair Questions? Ask a Mechanic for Answers ASAP
Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.
This can be due to a fault with a shift solenoid or torque converter solenoid in the transmission valve body at fault.I have also seen the valve body itself fail on this model here requiring replacement when it does fail to correct this fault here.
If the check engine light has come on with this issue here the first thing that needs done is to have the fault codes checked to see what codes are set.Once this has been done any codes set need to be diagnosed to locate and repair this fault.The codes are checked using a scan tool or computer that will plug into your vehicle that can communicate with all computers in your vehicle.
Valve body failure and shift solenoid failure are most common for this issue here.This will have to be checked into further first having the codes checked then tested from there to pinpoint and repair this issue.
