Just curious, does it make a clack clack sound when it jerks? I am trying to diagnose something like that, happened once on my '96 after quickly shifting into reverse in the middle of a 3 point turn. But not when I slowly tried to reproduce it backing up, but that time it did squeak a little. I haven't driven it since, checked the U joints in the drive line and they are tight...

That was my first thought too. More throttle finally gets enough fluid & pressure to get reverse to engage.

Sounds like it might be tear down time. The reverse clutch is applied in M1 and reverse, but a problem with it shouldn't keep M1 from working,the way I see it.
Anyway here's the clutch,band, and one way clutch chart:

Did you bother trying to actually figure out what is causing it instead of "F*** it put a trans in it"? For all you know it will end up being a wasted job and wasted days only to figure out it never needed a transmission in the first place! If I pulled that crap at my dealer they would fire me before I could finish explaining myself! Diagnose the thing or get it to a shop if you don't know how to diag. Sheesh.
