Default 4L60E Checkballs

Can anyone tell me where to find info for the checkball locations in the 4L60E valve body? Lost reverse gear after rebuild kit was installed.
Thanks.

The only checkball pertaining to reverse is in the case, and won't cause a no reverse situation. Most likely the culprit is the solid teflon rings on the pump which can get torn very easily especially if the rings weren't "sized" long enough. You did use the tool, didn't you ???? :o

I'll email you with the correct checkball location anyway.

...no tool used. Guess I did a bad thing...
Is there a way to tell that the rings are damaged by looking at them?

Yes, if you pull the pump and find the rings are cut, or have a chunk missing out of them, then guess what?? :O

You can get it from your local trans parts supplier, or from a few places online.

These are my guys:

A great bunch of guys, and good pricing too. I do recommend that you order the 4L60E manual, and the update book. They both contain unbelieveably valueable information.
