Hey guys, I have a 1965 Impala with a 434C.I. small block, Holley Sniper EFI, 6l80E controlled by a PCS TCM-2650 from Zero Gravity Performance. I had the TCM flashed with a 2010 Corvette calibration (to use the lokar shifter with tap shift). The trans OS is 24254909. My problem is that the transmisson stays in limp home mode and has a U0101 DTC. I tried checking off the dtc as no error reported hoping that the trans would then operate normally. That did not work. My diag guy told me that he thinks the OS in the TCM-2650 doesn't match up with the TCM, so I wanted to try segment swapping a 2008 OS into the TCM 2650 but there isn't even an option to segment swap when I open the tunes in VCM editor. Has anybody in here used the Zero Gravity unit? Or does anybody know anything that I can do with Hptuners to correct this issue?
