Any help with these numbers would be appreciated. I'm fairly sure this is a '50's era tranny as it's cast iron but I have no idea what it's out of.

Tail housing: 3880042, GM11, B87

Main housing: 3858986, B167

Cover plate: 3858992, B147

Thanks in advance,

John

Those casting #'s don't appear to be 50's castings..possibly 67...??? most 3 speeds were cast iron

Thanks Panther,

Still need to know what this tranny came from if possible. Any help would be appreciated.

according to colvins chev by numbers, main housing(3858986) and cover(3858992)were 66, 67 saginaw 3spd, available in 66 in pass.,chevy II, chevelle, 67 in pass.,vette,chev II, chevelle, camaro. could other cast # be 3860042? it would coinside with the other cast #s if so. hope that helps.

68RS406,

Thanks for the info. Big help. Got a friend with this tranny in an early '60's pickup with a column shifter and he wants to convert to a floor shift and needed to know what the tranny came from. Thanks again!
