Thanks for the info good to know it can be flashed/paired with the DME

I am reluctant to buy a second hand unit and have the same problems, hoping someone might have experience with flashing a new or rebuilt unit. Do we think this would be the same? Assuming I would just have to pay close attention to make sure the part numbers and hardware numbers match my existing? Given these trannies were in SO many different manufacturer vehicles I’m guessing I can’t use a TCM from a 6hp26 out of a land rover for example?

My unit is a Bosch 7557063 control unit GS19
