4l80e acting weird
Have a 4l80e that I pulled from my old truck to put in my 03. Rebuilt it last year and has roughly 5k miles on it. Ran great when pulled. I had it covered for the winter and recently got it installed in my 03.
Filled it with fluids, checked torque converter spacing, and wiring. Fired it up, moved forwards and back yesterday. Topped off fluids. Went today to test it out and only went forwards in all gears, including park. Shut it down, rechecked everything. Started backup and doesnt move at all.
line pressure was 200psi in reverse, and 100psi in forward gears. No movement with throttle. Pulled main plug and had 200psi for pressure. Reconnected harness , and checked hptuners. Had TC input shaft speed, no output. Rechecked torque converter spacing.
what am I missing ? I don't imagine anything internally went bad over winter, it was covered but anything is possible. Any tests I can do before I pull the tranny ?
