Thanks for the attempt at humor, MrCjames, but I'm really not in the mood right now. The only saving grace on this whole bull**** episode is the really fantastic service loaner they gave me - brand new C280 4matic with a killer sound system, with Mars Red exterior. I'm almost willing to tell them to keep the C36 if I can keep the C280.

Anyway, the only fault code I'm aware of is the #109, and I do not know what the units are on that 620/8000 reading, nor do I know what test those results represent. I do not have any kind of readout or other documentation - all my correspondence with the Assistant Service Manager (ASM) has been via telephone. I did discuss the TSB regarding the modifications to the connector and possibility of fluid seepage with the ASM, and he did say that they checked for fluid in the module housing and found none, also that they Ohmed out the wiring harness to confirm connectivity through the harness. I do expect to talk to him tomorrow, so I'll see if I can press him for further details.

I agree that it's an electronics issue and unlikely to be an internal transmission problem, since it's okay for a while and then isn't. Thank you all for your suggestions and stay tuned...

Best Regards,
Rob
