Tranny identification

I am interested in identifying the transmission in my 72 c20. It is a four speed on the floor and says option number M20 on the inside of the glove box on the original sticker? Is this a Muncie M20, because that is a normal ratio tranny, not a granny first gear?

Re: Tranny identification

It should be an SM/465. That's what a 72 granny low 4 spd is...
