4r100 no overdrive
01 excursion. 4r100, fresh rebuild, supposed to be a stage 5 with a monster torque converter. I put the tranny in, hooked everything up, it’s full of fluid, shifts fine in every gear but won’t shift into O/D. It will redline in 3rd but won’t shift out. Reverse will kinda shudder a little sometimes too, idk if that has anything to do with it. No programmer, all stock. O/D light flashing so hooked up a scanner, i don’t remember what the codes were exactly but it’s getting the command to shift into every gear, solenoids are on and off when they’re supposed to be. I’m just at a complete loss and I’d like some insight before I probably have to tear into it. Thanks guys!
