Help ID my 833

[Joe Mc]

7/8" X 3" casting boss on r/side "only" has the following stamped into it: PP833 4644, no partial vin or other markings. Nothing to the right of this number either?

Posted this on the 4 speed forum over the weekend and nothing yet. Figured I'd try here as I cruise this forum more than other ones and figure most other guys do the same.

As noted in 4 Speed forum:
Cast on r/side under boss is: C399129 L, there's a 4 cast slightly above the 3 in the previous series.

Tail has cast: C99126-2

Side cover (Inter-lock type) cast: C-99386

Input retainer cast: Real hard to make out but looks like C9A(or 4?)786

From what I've read on Brewers, based on the "one groove on the cluster" it's a 3:09, 23 spline, but at this point I'm confused.

I'd like to know, if possible; gear ratios, build date (that 10,000 day calendar has my head spinning = duh!) and is this thing worth rebuilding?

Thanks guys.

is it 23 spline? just cuz brewers said you should look

Will post up pics and count the input and output splines this weekend.

input is all that is necessary as the out put is the same as a 727, 29 spline i think...

if it is an early trans it will have a ball and trunnion flange on it...

No ball and trunnion flange. Used to have one of those when I owned it before, but along with that my buddy got rid of the blow bell, aluminum flywheel, and Mr. Gasket V-Gate shifter. At lease he replaced the V-Gate with a similar Hurst Ram 4. Just don't understand why he let the V-Gate go - I had just purchased new Mr. Gasket Shift rods and steel bushings??? Oh well that's what I get for selling it. At least I was able to convince him to sell it back to me at 5 times less than what I sold it to him for. He had someone (questionable) rebuild the engine, I drove it once and it ran pretty good . . .

Your tranny was built on mon april 15 1974,and it was on the night shift.Measure the front retainer bearing to see if its a regular 4 speed or a O/D unit .The O/D unit will have a shift lever pointing down and one pointing up,and can be in cast iron case or aluminum.mrmopartech

 

[Joe Mc]

A 74 unit, thanks.

Levers were pointing up.

23 spline.

Front Bearing Retainer dimensions
1.248" X 4.354" = Chry P/N 3410395

Thus far, based on spline count and year and single groove in bottom gear cluster, it looks like a 3.09 1st unit. At lease it isn't an OD unit. :-k
Anyone want to confirm or add opinion?
