Can someone please help me ID what kind of auto transmission is on my 68 FB. The pan is square on two ends. The other two ends are at a 45 degree angles. Both of the angle ends are not the same. One is a longer angle than the other. Sorry for the poor description. I always thought I had a TH350 but I do not think this is the case. Polyglide? _______ | | | | | | \ / \______ Again sorry for the horrible drawing. It looks something like that. sort of. Thanks
