If you didn't have this trouble before the u-joint issue, then I think a look inside that trans is in order...



In 50 years of messing with '833s, I've only found two causes for "popping out of gear"...

> Shift linkage maladjusted so the slider isn't 100% engaged

> Worn dog teeth on the speed gear (in your case, the main drive pinion). You have to look carefully, kind of a tapered or diagonal wear pattern.

Hard to imagine, though, how a bad u-joint could cause either of these defects. I'm thinking -- long shot -- bent / twisted mainshaft?
