4l80e troubleshooting Well here we go.. first i lost reverse and OD so i pulled the tranny, bought a book and rebuilt it myself, while doing so i found the direct clutch frictions were fried, and the direct clutch piston was broken, so replaced all the frictions, replaced the piston with a newer steel one, and replaced all the seals throughout the tranny. Put the trans back in, now i have reverse but it won't shift from 1st gear, pulled the valve body and tested all of my solenoids they seem to be working, check ***** were in place, however i did find an accumulator feed screen was cracked so i replaced it and put it back together to find the same problem, no shifting from 1st....i'm lost as to where i ***'d up..lol..please help

yes it's showing correct speed, i've tried pulling the fuse and it doesn't start at all, but i haven't tried pulling the plug yet. i'll give it a shot today. Would it be throwing a code if it was an electronic issue?
