Hi everyone,

new to the site and i have been searching all the post but cant find my answer and i hope someone can help me.

I just got done rebuilding my 4l80e ( including all new electronics ,wiring, torque converter)and it runs great in all forward gears, and goes into reverse fine when it is cold but once the trans warms up it delays going into reverse. I know the band is not broke, it will engine brake in first gear great. any ideas? Before the rebuild reverse was fine. i rebuilt it because i had intermittant overdrive.

Thanks C.L.
