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!
