I know that there have been a few Studes with A833 4 speeds swapped in. The A833 is a strong transmission, but it is heavy and probably overkill for most Studebaker performance. I pulled and reconditioned the A833 in my 71 Cuda years ago and it was about all I could manage to get it on the bench and later get it back in the car.
I did not realize that the overdrive versions ended up in a Chevy application, although I knew that Dodge used it in trucks and some cars. Unless there was a redesign, the overdrive version has a problem with excessive wear due to the shafts being driven differently than they were originally designed.Last edited by 52-fan; Yesterday at 02:50 PM.

I figured the trans was a little overkill for a Stude, but I wonder how much more than the "$75" you would need to get it to work?

The aluminum case would certainly make a difference in weight. Does the -10 mean that yours is overdrive?

Exploring the New Process A-833 Transmission
A super cheap alternative to an 11" clutch & Muncie / Borg Warner 4speed.
Are you looking to put a tough 4 speed & 11" clutch in your classic GM muscle car?
Did you get sticker shock when you found out what Muncies & 11" bells are going for? The average swap meet price on this set up is as follows:
$400 - $600 for used Muncie or Borg Warner Super T-10
$150 to $250 for a GM 11" bell or used Blow proof.
$20 to $40 for 11" clutch fork
$50 to $100 for usable 11" flywheel.
$75 to $150 for a good used Hurst Shifter
You are looking at spending between $700 & $1100 !
I'll let you in on a little secret. I found a set up which I can purchase at my local Easy Pull Junkyard for a total of $75. No kidding. It's the New Process A 833 4 speed over drive transmission found in 1980 to 85 Chevy 1/2 ton, 2 wheel drive trucks. It comes with an 11" flywheel & bell housing, & Hurst shifter. The transmission has all the same dimensions as a Muncie other that it is a little fatter.
The trans mount, input & output is in the same location as this 68 M20 Muncie.
The only major difference is the position of the ears that bolt to the bell housing.
The shifter is a Hurst and resembles a Competition PLUS with a grease fitting.
The bell housing has that un-usual bolt pattern for the trans. It is actually big enough for a 12" clutch. The bell also had the ball mounted on the side for a clutch Z-bar.
Since the New Process A 883 transmission is a truck transmission, it is
tough. I tested it. I'll tell you about it later. It's only down fall
might actually be a plus if your are a cruiser, not a racer. The gearing
is not ideal for drag racing. The gearing is :
1st = 3.09
2nd = 1.67
3rd = 1.00
4th = 0.73
The gearing is too wide a ratio to be effective on the track. If your a
cruiser, that's a different story. That low first gear makes it perfect
for peeling out at the local cruise and the over drive gear makes
it good on gas while cruising or on highways.
I wanted to try this set up out and had the perfect candidate. This 65 Impala SS.
I wanted to put it in a car capable of braking the trans for test purposes. This 4000 lb bomber has a mild 350 and a 12 bolt posi with 4:10 gears. It was originally stick but someone had put an automatic in it. The flywheel & bell bolted right in. The clutch linkage all fell right into place with no fabricating.
The transmission bolted to the stock Impala crossmember and all the shifter linkage cleared with no issues. Even the speedometer cable bolted right up, but the gearing is way off.
The only problem I ran into was the 3rd & 4th gear linkage arm on the shifter hit the inside on the trans hump. I did have to notch the floor.
When I was done with the swap, I was pleasantly surprised to find the truck shifter only sat 1" forward from the factory Impala position. I was able to install the SS console (1" forward of course) and even screw on an original old white Hurst shifter ball.
Not bad for $75 and some bloody knuckles.
So,
how does it drive? With the 4:10 gears in the rear, 1st is real
low. 2nd feels nice but I think that with a higher rear gear, the gap in
the ratio between 1st & 2nd could be more noticeable. 3rd is a
great cruising gear and 4th, the over drive gear really helps keep the
RPM down on the high way. At 70 MPH, the motor was turning 2900 RPM.
But
will it take abuse ? I took the old girl out and did some 3000 &
4000 RPM launches. The car didn't hook up. The tires just smoked. I then
did some 5000 RPM flat shifts (hold the gas on the floor boards and
shift). This always blew my Muncies apart. The A 833 took the abuse as
I burned rubber right through 2nd gear and chirped 3rd. This was
all done on a closed course ... of course. Hee Hee.
I
doubt if this swap increased the value of my Impala but I don't care.
It's the perfect swap for your cheap daily driver or weekend cruiser.
Your Welcome,
