What did the A833 come in?

Looking at this ‘83 C20 in Texas for $1200, not running. They say it has a 6.2/NP833 manual in it. I’d like to get one with this gearbox setup, and the 6.2 would be reliable or I could put my 305 in it. Does this sound like a reasonable combo, or are they pulling my lariat? This transmission is not common which begs my suspicion. I’d prefer this over an SM465 so it wouldn’t be the equivalent of a Model T Ford on the interstate or larger highways. @yevgenievich this isn’t too far from you, huh?

Looks like a good truck but why is it listed as an avalanche? Anyone correct me if im wrong but isnt an 833 not a gm trans?

It’s done that way automatically for some reason. The truck I sold yesterday also got auto listed as an Avalanche. I assumed New Process built them for both GM and Chrysler applications.

My first inclination was chrysler... like dakota or older ram.

It is in the land of cheap squares(east of dallas). Good 5 hours from me. All square parts and trucks in that area tend to be cheaper than anywhere else in Texas

I bought this truck the other day sight unseen as a work truck, and it was kind of a mess for my taste. I’d say it’s from hanging around here too long, and some people don’t mind halfassery, but I can spot that fly by night crap a mile away.

Hmm, I might need to make a pilgrimage over there. I’d settle for an SM465, but I want overdrive. It’s about six hours or so from me, but I’d say worth it to have something to pull trailers with and haul stuff on the bed.

I know a guy with that year, engine, trans combo. It is kind of a unicorn but the factory did make them.

 

[1987 GMC Jimmy]

Interesting. If it’s still available in a week, I’m gonna go get it. If not, oh well.

 

[Keith Seymore]

Agree; it's a legit combination. It's a New Process A833.

From what I understand, they were available behind the civilian 6.2, the 305, and the 4.3 v6.

 

[HotRodPC]

I'd be all over that deal with the A833. Yes, it's legit and what we'd call rare in Squares but it is an OEM factory combo, RPO codes MY6 or MM7 depending on how or why it was optioned. Keith knows more about the options.

In Chrysler applications it was a A833 in GM it was NP833, essentially the same transmission, from what I understand it is a Legendary Mopar transmission. My truck was a factory 305 with an NP833 behind it. I was happy with it, I plan on rebuilding it prior to reinstalling it during my restoration

No. A833-OD was a Chrysler transmission for cars and trucks.

In only 82-83 they were put into CHEVY Trucks with the 6.2L Diesel engine Or Gasoline... there's only Supposeaably 200 ever made. Limited run I have Very close Older friends hell 20-30 yrs than me who's mentioned they've only seen 1-5 within the last 20-25 years with that Engine/Trans Combo. They are the Holy Grail to us 6.2/6.5L Guys.
