m6->a4, wont shift out of 1st My car is a 98Z, trans is 4L60E from a 2000 Chevy 1500, repinned pcm with the 13 wires from the large connector on the trans. No PNP switch is hooked up at all. Retuned my pcm with the transmission portion of the tune attached. Trans is full of fluid and not overfilled. After letting it warm up completely, I drove it and it wont shift out of 1st gear. I put the car on stands and tried to make it shift to 2nd using HP tuners and it still wouldnt shift. Any ideas?

Flashed in a factory tune and still getting no shift. I am going to pull the plug from the trans and check which pins have what voltage under what condition. Anyone have any input as to what each pin should be reading volt wise?

This is how my harness is wired. (Trans harness pin-ecm pin)A-R35, B-R40, C-B39, D-B36, E-12 VOLT switched power, L-B13, M-spliced into B25, N-R25, P-R61, R-R22, S-R34, T-B32, U-B33. Anyone know if all this seems to look right?
