4l80e Not Move in reverse and drive Hello, I had a question to see if you could help me, I have a 4l80e transmission, I repaired it in reverse and it does not move as soon as it is applied, it tries to move and it skids but in 3, 2 and 1 when I select them it works fine. thank you

input sprag is damaged or installed wrong. Or you replaced it with the wrong variety (there are 2 different types)
in 3/2/1 the overrun clutch is "doing the job" of the input sprag
Need to teardown and correct
