A833 trans alignment issue? Help

I don't believe a bad pilot bushing would cause the problem you're describing. When the clutch is disengaged, the input shaft and the crankshaft are rotating at different speeds. The pilot bushing's main function is to allow for this difference in rotational speeds. This is why a faulty pilot bushing makes its most noise when the pedal is depressed and clutch is disengaged.

I not trying to insult your intelligence, but let’s run through the basics to help isolate the problem. When your clutch pedal is depressed, the clutch linkage moves the clutch fork to press the throw out bearing into the pressure plate. This movement releases the pressure from the clutch disc so that the clutch disc spins freely. When you release the clutch pedal the pressure plate sandwiches the clutch disc against the flywheel and now the engine is spinning the input shaft of the transmission.

Assuming this is not a trans or shift linkage problem, then the problem is somewhere in the clutch linkage (mechanical clutch), clutch adjustment/adjustment rod, clutch fork, clutch fork bracket (inside bellhousing), throw out bearing, or pressure plate.

The problem started after you changed the clutch disc/pressure plate. Possible problem areas: Throw out bearing is bad (did you replace it?), bent fork bracket, bent fork, bent adjustment rod, misadjusted clutch rod? Maybe it is the new pressure plate?

I don’t know what style bell housing you have, but if it’s possible to remove an inspection cover and fork boot and look inside while a helper works the clutch you can inspect for the proper movement.

Hope this helps.
