Hey all,
I just swapped an M37 NP420 transmission into my 1955 Civilian Power Wagon. Swapped it for the original crash box tranny. Anyway, I have some noises that I didn't have before the swap. When I push the clutch in and start the truck (in neutral), everything is as it should be,that is, normal and quiet.
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.
Could it be the synchronizer's spinning creating the drag? Just want to find out if this is normal for the synchro tranny?
Oh, I test drove it around the block and it shifts fine, just like it should. Reverse works great too.
Ideas?
Thanks for your help.
