Transmission gear whine
I distinctly remember that the M20 transmission had a significant and very pleasant gear whine as I was rowing thru the gear box.
My recently acquired '65 couple has almost no gear whine..It's hardly audible. I see on you tube that cars being driven exhibit that gear whine, especially in first gear..
I don't know if the transmission was rebuilt, I have no indication that it was as it's a numbers matching drive train and the records I have show some engine work but nothing for the tranny or rear end.
Can anyone shed some light on why a quiet transmission. By the way, it functions perfectly just don't make those pretty gear sounds that I remember from my youth.
