1996 with a 1998 engine/tranny. Shift 1/2 accumulator lower spring broke. I pulled the tranny, replaced all seals and clutch packs, new Shift 1/2 accumulator spring/piston, new reverse servo. Put the tranny back on the block, making sure the torque converter was properly seated (end of shaft is 1/8" lower than a straight edge held across the tranny case edges).
Engine can be turned by hand, estimating the torque to be around 80 ft lbs to move it. Compression is solid. When I try and start it, you can hear it turning very slowly (probably moves about 15 degrees each key turn). Pulled the spark plugs, now it turns about 90 degrees each key turn. But either way, clearly not fast enough to actually start.
Ideas on what could cause this? Possible misalignment within the tranny components?
