I have one I haven't installed yet. This trans is in the Chrysler A-833 family. Most folks on the board seem to have a low opinion of it. The Chrysler guys seem to like the A-833 though.

Sounds like it would be a good swap into your '70.
If I could ever find one in a JY, I'd keep it until I get my hands on a 2wd project.

I have one in my 81 pickup, it came as original equipment in GM's fuel economy package, ESC 305, 4spd OD, and 2.56 rear gear. I swapped my gears for 3.08 and have plans to go with 3.73's. I've also heard that the same trans was available behind the 454's in a pickup, but I can't confirm this. It's a good trans in my opinion, they mated them to a 12" clutch. GM referred to the trans as a MY6. The OD is .73. I have an old road test from a magazine from back in 1981, if there aren't any copyright issues I can scan and post it.

what kind of mileage to you get? Does it clear the stock bench seat, I assume it does since it was a factory installation.

SSC's76 · 09-16-2005, 05:06 PM

DC used them behind I6's and 440's fairly wide range in thier apps. Ive never seen one behind a 454. If you do some digging in the drivetrain/engine fourm theres pics of one installed into a 73-86.

It used to get in the lower mid 20's on the highway. I installed a cam, headers, and richened the carb jetting and the mileage decreased considerably.

The shifter clears the seat without a problem. The shifters were manufactured for GM by Hurst.

The A883 that has overdrive isn't the same as what was used behind the 440. It is the same tranny that Dodge used in it trucks that have a rep of being weak. They were mostly used in Diesel apps. They never came in a pickup behind a 454 (last year was 1979 for BBC) or 350 (1980 was the last year for the 350 until 1987 in a 1/2T pickup).
