2008 GL CDI bought new 2009, in Canada, Have towed 8000# Airstream trailer all over USA & Canada, from time to time. No previous transmission problems but sometimes used to clunk, when I put it in gear. Transmission paddle shifters work fine. MB Dealer diagnosed and Replaced Torque Convertor. Flushed and replaced transmission Fluid. Starts OK BUT has problem shifting into gear, reverse more than forward, when engine is cold but especially when the car has been parked nose down overnight. Almost feels like brakes are on? (Not the case!). May stall a few times if cold. Runs fine, shifts smooth once it gets warmed up. No noticeable clunking when I put it in gear now. Could the problem be low transmission fluid level or wrong type of Fluid? Too Viscous i.e. heavy.

drive car without changing gear to work shop sign , after couple of times the car started but after a mile it started to jump. first time

The evaporator temperature was measured at 13.5c front and 16.5c rear, Refrigerant pressure at 11 bar, with coolent temp at 87c. The MB service told me initially everything is fine but on taking a second and third time they now say the compressor is faulty while the reading above are the same all the time. The compressor kicks in on switching the AC on. Can I relay on the MB Service and change the Compressor?

Simple right? Need to change the GL320 engine oil and filter and then reset the dashboard service warning for a future time. I am certain it is all a simple process, but I would appreciate it detailed explained so I do it right. Thanks!
