While researching a manual tranny with 700R gearing, I came across the following. As I understand my research, this trans, in the '81-'86 GM Truck configuration has the same input and output splines as a stock Van. That said you MUST use the bellhousing that was designed for this trans. The engine side of the bell housing bolts to our blocks, but the tranny side is specific to this trans. I am not sure of the clutch linkage(yet).

New Process A833

4-speed transmission, with all forward speeds synchronized. Manufactured in both direct drive and overdrive models. 10 Bolt shift cover mounted on left side of transmission case. Early models had iron cases and late model cases are aluminum. Case length measures 10 5/8 . Used in Chrysler passenger cars 1964-80, Dodge trucks 1976-85, and 1981-86 General Motors trucks. GM models may be identified as RPO code MY6 Produced in 2 and 4 wheel drive versions

John,
I believe i have one of the versions of that trans that until now nobody has been able to identify for me.
Its not the O/D Version ,but has the aluminum case, 10 bolt side cover . It is the Exact length of the 3sp saginaw with the spline counts on input and output shafts identical to the sag. Its mounting point is on the lower side of the tailshaft.
All i was told when i got it was that it was out of a mid 80s chev P/u. Looks like it was set up by the factory with hydraulic clutch using an external slave cylinder at the bellhousing
I plan on using this trans in my van because i feel the need to just shift one more time!!!!
What is your opinion on this trans behind a mildly built 283 and in front of a 3:08 rear???
Looking forward to your reply and any more info you may be able to provide!!!
THANKS!!!

won't OD with a 3.08 rear be too tall? good for fuel milage and should be o.k. but not the way i would go. i have 700r4 with 3.36 gears. good balance of off the line torque and keeping rpm's down on highway. 308's would squeeze a few more mpg out of it and lose a little on the bottom. if anything, i would go the other way, 355's or 373's but i dont care about milage. its all in what you want out of it. evan with 308's, your still lower than th350 with stock 336 gears, and miles ahead of the powerglide.

Mac - - Glad I could get you fired up :) Like "jrinaman" said about the gearing. I have 28" tires, 3.73 gears, & a 700R. That combo runs at 2150 RPMS @ 70 MPH. With the 3.08s the Van would need some short gearing,

If you decide not to use the tranny, I will buy it :)

This is the article where I found the info - http://www.motivegear.com/tech_info/tranny_guide/tranny_guide.html

Good tech info - http://www.hemmings.com/mus/stories/2005/03/01/hmn_feature17.html

I think a few of you know that I am in day 28 of cleaning, organizing, re-configuring my garage (40 years of "collecting"). In the process I have found a 455 Olds engine, 3.42 posi rear-end, Muncie Rock Crusher (?), 11" clutch assembly, pusher fan, a couple of Q-jets, chrome alternator, a set of bucket seats, a Van straight axle - - so what??? If I had a '54 Chevy body . . . they would all come together as a neat "gasser" - - -which is why I went looking for a manual trans with 700R gearing

Do I have one last build in me?!?!?! . . . . Any nice body '54's out there???

Good Luck with the garage John!!!
No i dont want to sell the trans. I think its gonna work for me.
I had enough around town "FUN" with the with the way the van was set up before. 4:11 rear with the three spd manual. Ive always wanted it more (comfortable) on the long hwy drives though.
So now with the 3:08 rpms are at 3200 at 70 with a 26" tall tire, down from about 3900/4000 with the 4:11s
Yes its a little sluggish gettin her goin out of 1st i'm ok with that . How much more RPMs do you think i will lose in fourth with the A 833???

Bionic John, I wish I had time to clean and organize my garage. Looks good! And inspiring.
Mac, you would drop to about 2200 RPM, which is actually great... (3200 X .70 = 2240)
Correct me if my math is wrong...

the olds 455 with a 3.42 gear would go in the van. all you need is a dual quad intake to use the 2 quadrajets.

Turbo - - the bionic is more true than you know - - in the last three years I have had a hip and both knees replaced . . . which is why the garage is out of control. I would work as long as I could, without cleaning up. Now 28 days later, I am seeing some daylight :)

Mac 3.08 gears and that OD tranny would be fun in 1st gear, As for 4th gear, I don't see many hills in it's future

being in ohio, you are fairly close to the nats next year joyride. if your van is not ready, rent a u-haul or enterprise van and head on up. there will be some opportunity to link up with some of us easterners coming across if you want to travel in numbers. john
