Slips out of reverse (1 Viewer)

[CruisinEveryDay]

Hey guys. I searched through the threads that covered this but didn't find a conclusive answers. My 97 will ALWAYS slip out of reverse when backing up a steep hill.
Why is this happening? Get technical for me.
Was there ever a recall done by Toyota because I know others have this issue?
What needs to be done to fix it? (full tranny rebuild or swap?)
Are there any tricks I can use to back up hills until I can afford the repairs?
Thank you for your help.

When you say "slips out of reverse", does it simply slip into neutral or does it actually make a grinding noise?

A grinding noise. The truck kind of shutters. The engine then revs and the truck will not move. So I guess it may be in neutral. What do you think?

I had this problem before and made a thread about it years ago (turned out I wasn't alone)

Only happened when I was reversing under load in high range with a quick stab of the throttle.

Found that if I waited a few seconds after shifting into reverse before applying throttle, the problem didn't occur, so that's what I've been doing ever since and never had the issue again

Ok cool. I've been reading up more and apparently you can have a valve spring switched out to stop the problem permanently
