98 nv3500
I'm in the process of swapping the sm465 out of my 79 to an nv3500. I picked one up out of a 98 k1500 that allegedly worked fine, but when i spin the input shaft by hand the output shaft doesn't spin unless it's in 4th. It feels like it goes into the gears smooth and there's no nasty noises. Someone told me that it might need more centrifugal force to engage the gears. Is that true or do I need to tear into it and do a rebuild?
