Hey all, I have recently just finished a 5.2 magnum swap on my 01 tj. Rebuilt 5.2 magnum mated with an NV3500 Manual trans. NP231 T-case from a Cherokee. I did not touch the trans before installing it because I have never rebuilt a trans before. I did however rebuild the motor and that went flawlessly. Though I could not help but notice a constant grind in every single gear. The transmission itself shifts butter smooth. The sound is more noticeable at high speeds. especially going from 4th gear to 5th gear. When I push the clutch in, taking the torque off the trans, the sound is absolutely terrifying. But shifts butter smooth. I'm thinking I might have to rebuild the trans, but I'm not too sure yet. Any suggestions? Maybe input shaft bearing?
