Had this car come in today with overshift light flashing and CEL on. Felt like it was stuck in winter mode but tapped on switch and car started to drive normally but the fault lights were still on. Pulled 1 code from ECM 530d which just means that the trans has requested the ECM to turn the CEL light on,and 3 codes in the TCM,haven't seen these ..Yet. P0734 gear ratio fault in 4, TCM000b, TCM 000c, which are hyd. faluts for Sol. #1&2. Are these a trans condeming faults or gummed up solenoid valves? Thanks for the help, Alan
