I have not check TCM All is dry at the plug in the tranny. It actually looks like there is a crack and small hole in the connecting harness plug. Does that tell me anything? Is there a guide for checking the TCM? That happened with my 01 e320 I had a myriad of warning lights and then finally a no start condition

This 2000 e430 will occasionally throw check engine code p0715 and then it stays hung in the current gear until you can pullover and restart. Resets every time. Some times can drive all day without issue. Thanks for the advice. Any and all is appreciated
