02 duramax P1621
on my edge tuner it says TCM long term memory it sent my trans in limp mode once after i shifted down manually when in tow haul it didnt want to shift down on its own. No big deal just cleared the code and kept driving. The code comes back right away no mater what power level im in even stock. Fixing to replace it but was woundering if the TCM is vin specific. If anyone knows it would sure help. Thanks
