I can't get a TCM read out of my 2007 LBZ. it keeps failing on a time out error. Anyone else experience this or have any suggestions how to get it to complete? Thinking of doing a bench harness for the TCM to take everything else off the bus.
Thanks in advance

I haven’t personally had any issues reading them, even on efi live tuned vehicles.
Reads & writes fine with ECM & TCM on a bench harness...Tech 2 talks with both modules fine in the vehicle...guess I'll try some fuse pulling on other modules to try and get HP Tuners to work on the TCM in the vehicle..
