Need Help trying to ID a A833 trans. Casting on the side of the case is C99129-H

Can anyone help with what this is out of or what it fits?

Thanks.

I think it would be easier and more useful to identify the type of tail shaft you have, the type of side cover, and the size of the input spline 23 or 18.

From there you will be able to ID what it fits and what years.... use this as a guide.

That casting number is the same on all cast iron 833 manicases , TOTALLY USELESS in trying to identify the trans .

Is it a 23 spline or 18 spline ?

Does the tailshaft have 1 shifter mounting boss or 2 ?

If 2 it's a B/E body trans.

If 1 is the mount in front of the trans mount or behind it ?

If in front it's a B body trans , behind A body trans .

List all the information on the VIN pad or a clear photo of it as well.

Here are two of the possible configurations
