I just installed my rebuilt Muncie. It was rebuilt by a local tranny shop that has a good rep. When I installed it I put in a new Centerforce II clutch. I had the Flywheel resurfaced. and thought I'd be golden. Drove it about 15 miles and it seemed fine. Now I have a major Vibration.
I spoke to Centerforce and asked if they thought it was the clutch or tranny. He said probably not the Clutch but there have been problems when people don't use the correct bolts when installing the clutch. He said the bolts need to be shoulder bolts. If not the clutch could slip 0.030" and cause the vibration. I don't remember if they were shoulder bolts or not.
It seems more in 1st and 3rd gear and when the car is on jack stands and you rev it a little you can see the engine vibrate. I checked the wires, engine mounts etc..and they seem fine. I beleive it's definately in the clutch or tranny. If it is the tranny it would be covered by the tranny shop if not it's my problem.
Any ideas ???
