T-10 I.D. Help Please
Can anyone help in the I.D.ing this T-10?
Main case is cast iron, then an aluminum spacer, then cast iron rear case.
Front case cast in numbers are: 11/69 and T10-1B over W.G.DIV. Stamped next to the 9 bolt curved bottom cover is: WD 2892. Cast in the rear case is B.18.74. It has a fine spline output shaft.
Thanks, Frank

FrankC,
With the "aluminum spacer" it sounds like a "Super T-10". I don`t think the early T-10 had the midplate. Is the input shaft coarse or fine and how many rings??????? ....redvetracr

Thanks revetracr. I agree that the early T-10's didn't have any spacer, at least any that I remember. Some of the markings imply that it's a late model T-10 and could be a super type. Where I'm confused is the cast iron case and tail shaft housing. I thought that stuff went south in the late 50's. here's some more info and answers to your questions. Course or fine input shaft, course I guess. 10 Spline (normal old G.M.), no rings, fine spline output like turbo 350. Two slightly overlapping sets of shifter mount holes. I think they are all tapped, but I guess I need to look tonight...Thanks, Frank

FrankC,
I made an error, the t-10 DID have a mid plate, BUT if your sure it`s the small (T-350) output shaft then it`s probably a T-10 and not a "Super".

WOW, that was quick! It really had a spacer? Boy I don't remember that at all. I posted on the C3 board this morning in hopes of getting some other responses as I thought it was leaning towards a super T-10 that I thought came out in the late 60's+. I'll edit and add your correction. What about that cast iron thing? Did they use cast iron after the late 50's? Thanks, Frank

Sorry I just saw this thread. Yes the early T10 had a spacer, this is what everything was actually attached to. I just finished building one for a 57 4spd.
Is the main case aluminum or cast iron?

Re: T-10 I.D. Help Please (Frank C)
Where is T10-1B located, is it above or below the fill plug. Not the drain plug but the upper fill plug. If it is above it the fill plug then it is an early T10 if not the tranny is probably out of a truck which would make since with the 11/69 date and the 74 date on the tail housing. All the early T10 through 63 were course spline.
