I’d say the pinion nut is loose. That’s causing some gear mesh noise. If the pinion nut wasn’t scribed before starting, it may be appropriate to disassemble and at least replace pinion bearings, crush sleeve, and pinion nut. Then the rotating torque can be set exactly right. You have to sneak up on the correct torque. Too far, and the crush sleeve is ruined. Raytech makes a “Smart Sleeve” that’s much easier to crush.

I was told if too loose, it creates a "whine" sound, and if too tight, it makes a "growl", "grind" type sound!

Any truth to that?

I'd just like to get it fixed correctly, so it's quiet like it was prior to the seal change, and Tremec "TKX" install!

Does the "Tremec" transmission have noise? Compared to a Muncie "M-20"?

Just trying to learn, and thanks for the patience and advice!
