There is nothing wrong with a Muncie trans especially the M-22. I assume you know how to shift. I've had a few of them and never replaced a clutch, transmission part, anything. You just have to know what you are doing.
Well if you never replaced a clutch, then you certainly didn't own the car long enough, and didn't shift the thing with any kind of authority. I have never owned an auto in my life, and I learned to drive behind the wheel of a '68 GTO when I was 15. I upgraded to a '69 Judge after a few years, had a brief affair with a 13,000 mile '68 Firebird 400 4-speed, I finally bought the Old Dominion B/FX 421SD headed,421 H.O. Tripower '65 GTO. That was my last Poncho, and that was 1983.
Muncie 4-speeds are poor, that is why I turned to Mopar. Unbushed aluminum cases, floating the rear bearing inbetween the front case and the tailshaft housing, not enough meat to keep the case straight... My mother bought me an Muncie M-22 for my 17th birthday because she was sick of the car sitting in the garage and her having to park outside. (yes she was VERY COOL, and a GTO fan) The problems with the Muncie were inherent, and while you could cruise a big block 'vette with one all day long, they couldn't take ANY kind of stress or they would pop gear teeth right off the gear. You should have seen the effort I had to put into launching that '68 GTO...The tranny couldn't take dumping the clutch at any kind of rpm due to the huge amount of torque, so I had to ride the thing out from just off idle. Argghhh...never again.
