Hi guys, I'm pulling the transmission out of my 69 Camaro and I'm just trying to figure out exactly what it is. I think its a Muncie M20. Can anyone verify?

Case# 3885010
P0315

Tailshaft Case # 3857584GM

Input Shaft: 10 spline, and it has 2 grooves on the input shaft

Output Shaft: 27 Spline

Side Cover: 7 bolts, 3884685

IF it's never been into (and parts swapped)....
M-20.
Ratios:
1st - 2.52
2nd - 1.88
3rd - 1.46
4th - 1.00
Rev - 3.11

Based on your input/output shaft M20 - But someone could have changed it inside.
