What transmission do I have here.

Tail shaft numbers 099539

transmission stamped 0A181451
PP8333038 0159

On the body of trans C99129H

C-95664 Z

Thnks,

Wizard

If the input shaft has thick splines (18 splines) it is a 440/Hemi transmission. If it has thinner splines (23 splines) it is a small block or 383 transmission.

I am not up on the casting numbers but the 0 in the 0A181451 means 1970

Being a 1970 it should be a B/E body or A body not the older style B body only shown below.

All this is assuming it hasn't been Frankensteined together over the years.

This will help figure out what body type it is from



Hope it helps.

0A so it is from a 1970 B-body, but not a Charger.

Just counted the input splines and it is 23

It's from a 383 powered B body , should have 2 shifter mounts on the tailshaft.

How do you figure it's a 383? Were you able to look up the numbers previously mentioned or is there a reason it couldn't be a small block tranny?

I'm not saying you are wrong, I am just curious how you arrived at that so I will be better informed in the future.

I pulled it out of my backside mostly.

But after looking at Barry's site ... to confirm the hunch my backside was giving me ... Hamtramack Historical ... there weren't any 318 4 speed B bodies built so that would mean it was behind a big block and the only big block with a 23 spline 833 is a 383 powered car, and only 4bbl equipped in 1970.

Also same transmission LA or B engine, just the bellhousing would change.

It's not as easy as that after the 1967 model year.

The bearing retainer is different between a big block and a smallblock in 1970 ... that difference started for the 1968 model year when the Hemi 4 speed got the 308 front bearing and they were put behind the 440 which used the same bellhousing as a 383 ...
