Hey all I have to admit I know very little about these transmissions. But I do want to do a manual swap and am trying to decide between a 5 speed or an overdrive 833. I recently bought this as part of a package deal but I have no idea what it came out of or if it will even work in an A-body. Any help is appreciated.

The tailshaft looks to read 0-99127. These numbers were on the case:
H3 C 99129
PP833272761
96226482
0123

Looks like for a B body and the input has been cut for another application
 
Transmission was built on January 14, 1969.

The 99127 on the tailshaft housing, as well as the location of the shift pad and the lack of a second shift pad (later B/E tailshaft housings), indicates its a '69 B body transmission. It's not at all an ideal transmission to use in an A-body because of the shift pad location, it's in the wrong spot.

No, the reason the input was cut was for a Mopar "automatic" crank that had not been finish machined deep enough. This was suggested to me once, "in the seventies" and I ended up having the crank machined instead, as the crank was out of the engine. Some automatic cranks are not only not machined to proper bushing ID, they are not deep enough, either. Some of the late model stuff has shown up with very little depth beyond the converter snout.

That box is B/C body or could be used in a pickup. Same length, installed, as a 727. You could use it in an A body except building a shifter mount is a bit of a PITA. If you search, someone had a pattern of the adapter.
 
Thanks for the info guys!

I don't have the skills of the tools to fabricate that adapter. Is it possible to swap tailshafts with an A body unit? Possibly not worth the trouble. It's looking like I won't be able to use this trans.

As far as the input being cut, is it still usable? If I can't use it maybe a B body guy can.

Thanks again.

No, you can't swap just the tailshaft. You could swap it with a B/E tailshaft housing, and make the adaptor I linked to above for the rear mount. But in order to use an A-body tailshaft housing you would also have to swap the mainshaft in the transmission to an A-body mainshaft. The B/E body mainshafts are a different length than the A-body mainshafts, that's why the tailshaft housings are different lengths.

Yes, the input is fine. You can use it with a dakota roller input bearing, it fits into the rear register on the crankshaft and doesn't need the input to be as long. It's what most guys to if they have a crank that's not drilled for the 4 speed input.
 
Thanks 72 (I love your car btw.)

Looking more and more like this isn't the trans for me. Glad to know someone can use it though.
 
Thanks! :thumbsup:

I would try to find someone with a '69 B body. It will fit a few other years of the B/C bodies, but only like 66-69 without modifications and it's only correct for a '69.
