4l60e no reverse fix.

Put a line pressure gage (or visit a local Transmission shop) on the pressure test port and go for a drive to verify proper line pressure. Base pressure at idle in P,N,OD should be around 70psi and around 140psi in R. Max line pressure should be at least 190psi at WOT in 1st or 2nd, 225psi is optimum. If base pressure is low, the pump is worn out.Both the 4L60E and 4L60 have the same number of gear ratios as well as the same number of gears.
