Working on my 55 FFPW crashbox tranny swap for an M37 NP420. Anyway, got it in, but I have some noises that I didn't have before. When I push the clutch in and start the truck (in neutral), everything is as it should be,that is, normal.
However, when I let the clutch out, again in neutral, I get some noise from the clutch and it noticeably drags on the engine idle rpms. Sounds like the clutch disc is spinning and dragging on something? If I push the clutch pedal in, the noise stops and the rpms rise. This is new, it did not make these noises before the swap.
Oh, I test drove it around the block and it shifts fine, just like it should. Reverse works great too.
Ideas?
Thanks,
Clark
