Transmission Problems? Ask a Mechanic for Answers ASAP
Hi Brian, My name is ***** ***** will be glad to try to help. First verify if there was any burnt fluid or smell to the fluid or discoloration and signs of fine metal indicating internal problems requiring disassembly for repair. If clean try having the TCM reprogrammed/reflashed with the most current updated software as there were certain years that had a TSB for software issues causing shift problems. Let me know
I am not sure if an independent transmission shop has access to the software. usually it is exclusive to the dealer.
Call in with your VIN and see if there are any TSB Technical service bulletins for your VIN on this issue.
