4l60e No Reverse At Times

Automatic Transmission – 4l60e No Reverse – I bought a transmission off a guy. have worked awesome and this will be the first time ill be digging into a 4l60e.
One of the most common problems with the 4L60E is that the reverse gear will go out. Having no reverse can.
Pretty self explainatory. Reverse not even engaging. Tore down the tranny and replaced the clutches and reverse piston seals. Still I got.
HELP, I have a 2000 Z71, trans was working fine, wife came out from work started it up and now no reverse and it has a hard time shifting from.
(yes my fault I know, I was in the middle of nowhere and got desperate) I did this 3 times and finally I made a loud bang and now I have nothing for.
It shifts thru all of the forward gears but not reverse. When I got it back together it immediately went into reverse this time with no problems.
Time for a proper rebuild. Chances are the internal seals are hard with age and heat , frictions worn down thin. Two items create reverse gear.
Both times I shifted into drive, moved forward an inch or two, and then the transmission would shift into reverse. After that reverse continued to.
Today I tackle another trans from the Krusty Kenny Garage. We have not one but two 4L60E’s with problems.
This is a good example of why we focus on pattern failures and address the problem accordingly.
