I was wondering, does anyone know what would happen if you used the rear VSS on the 4l80e instead of the one transfer case?

Just a thought; do 2wd models use the rear wheel speed/rear abs to determine vehicle speed? Can you confirm that the TCM & PCM were flashed with correct gear ratio?

I didnt have this issue im having in the video until recently.. Ive had the 6l80e swap done and ECM swap and flashed over a year ago and didnt have this particular issue until now .. And i was thinking the same thing about rear abs but i dont see wires coming out of rear brakes .. Only wires on my brakes are the fromt ones .. Wondering how to tell if they are bad or whoch one since im not getting any codes saying bad sensors?

Will check mine today but i always check my fluids regularly and it was good last i checked.. Wont hurt to check again though .. The more i think about it the more im figuring its the torque converter but thats hust my feeling im having ... Especially with the stutterin through the drivetrain to the rear like it does when the rpms goe up n down

If you think it's torque converter I'd have a shop or someone with proper scan tool test drive and monitor torque converter slip % and command. Lot's of live data for this trans. Good luck! Swapped a 6L80E into my truck also and today it missed a 2-3 shift and hit the rev limiter on factory tune?!? Hope this wasn't a mistake because it drives so much better overall.
