A833 trans alignment issue? Help

All it would take (just pulling out of the air) would be a little dirt/ grit/ damage to the bushing bore, something that would compress the bushing enough to make it tight on the shaft. In this day and age of Chinendiaese parts, it's even not far fetched that the bushing was manufactured wrong. All I'm saying is this is possible and has happened. There was a recent discussion not very far back here.

But let's don't focus...............check EVERYTHING. I only mentioned it as a possibility.

Did you have the bell off? If so, are you sure it's bolted back up tight?

You sure the gearbox was clean on the mount face and bolted up tight?

You simply have to use your head, the process of checking and elimination. Do not rule anything out until you've PROVED it's ruled out.

I once put a 'Vett 10.5" diaphragm behind a 340, and THAT is a long story. I must'a had that thing in and out 4-5 times could NOT get it to release. Finally sent it into a (then) local rebuilder in Spokane, who could test the release on their press.............the PP was defective, plain and simple.
