Wally,
Here is what I saved in my "brains" file..
Good reading...
"The A833 is actually a MOPAR (Chrysler) transmission that Chevrolet offered as on option in some of their light duty pickups from 1981 through 1986. It is a 4 speed transmission (3 speed + 4th gear=overdrive).
The overdrive ratio is .73, which makes for nice cruising.
They are not an easy find, but are well worth your time if you can find one cheap.
The T5 trannies are much more commonplace and, therefore, easier to find. You'll probably pay less to have a T5 rebuilt than an A833.
I like the thought of a truck 4 speed in a truck. But I would have opted for a T5 if one from a V-6 S10 or V-8 Camaro had become available for a good price.
The gear ratios for the 4 speed A833 O.D. are as follows.
1st - 3.09
2nd - 1.67
3rd - 1.00
4th - 0.73
The gears are very close to those of the 700R4 (3.06,1.67,1.00,0.70). Works for me. I'm not too familiar with the T5 but I do know they come with a variety of ratios, from about a 4:1 first gear to an overdrive that's barely worth shifting to (about .85). Most fall in between.
There are many technical articles on the web about the T5 (and related) tranmissions. There may even be some swap info here on the Inliners site. Search around.

The only deal with them is that they are only rated at 275 pound foot b/c of the extremely deep first gear not like the regular Hemi type trans at probably above 450 pound foot, I figure easy.....
