Hi, can someone shed some light on an issue with this auto box on my son’s car. It’s a 2.1 CLA around 2014.
Problem is car will not drive when D or any gear selected. If put in D and try to drive engine vibrates violently. It was scanned and popped up these codes:
07e60 locking solenoid for park pawl malfunction
07156 rpm sensor ‘turbine wheel’ fault
09210 shift valve of inner shaft malfunction
07760 pressure regulator valve 2 not closing
So does it require gearbox ECU/ torque converter/gearbox itself? Thanks

I'm not an expert but the first thing on the list would be a big issue. Essentially the pawl that drops into the drive train to prevent it moving when in Park appears to be locked into the Park position. Changing this solenoid 'may' clear the issue. I would go to an independent garage and talk to them about it.
