Identify a 2.8 Chevy transmission Most any Chevrolet transmission will work, but the 2.8 didn't have much power, so stay away from a 400. A TH200 would be your best bet.
More than likely a metric TH200. Maybe a TH350 if you're lucky.
For automatic trannies: TH200 = 4.5 qts TH350 = 10 qts.
ANY transmission will fit as long as it has the B O P (Buick, Olsmobile, or Pontiac or Cadillac) bolt pattern. Be it the 200, 350, 700 ........
General Motors TH200 (M29) 3 Speed Automatic Transmission Use Dextron II ATF
The 231ci V6 came with a TH200 3 speed automatic. The V8 cars came with TH350 3 speed autos. I believe the manuals trans was a Muncie 4 speed
its a th200 metric. tci transmissions. about $1,500. or you can get a 350 turbo much cheaper. the 200 metric is the best choice, because it has 4 gears, and doesnt lag as much as the 350
There are several GM automatic transmissions that have the Chevy bolt pattern. Powerglide, TH200, TH2004R, TH350, TH375, TH400, TH700R4. These same transmissions also came with the BOP bolt pattern, so make sure you get one from a Chevy.
What is the transmission size? The Buick 3.8 's were used GM wide, and bolted up to TH200's, some 200r4's, and I believe TH350's could bolt up as well. Chevrolet trannys will not bolt up- their pattern is different.
Any transmission that will fit a gen 1 small block chevy. th200, th350, th400, th2004r, th700r4, muncie 4 speeds, T-10's, etc. As long as you get the right crossmember and driveshaft yolk you've got enough room to fit what you need. Just make sure the bell housing bolts are for a chevy. NEW ANSWER: The above answer is all wrong. If that truck is a 1/2 ton then it MUST have the 4L60E transmission put back in it. If it is a 3/4 ton then it must have the 4L80E put in it. reason being is because of the computer system and the transmission wiring harness. Yes all the above will bolt up to the engine but the truck will NEVER run right. The ECM / computer will not know what to do.
It may or may not, auto transmissions are fitted with different tails depending on the car they are mounted, if both trannies are for the same car, they will be of the same length, if two th350's come from different cars they might bew differrent in length, the wisest thing to do is to measure the th200 and then verify the 350 tranny is of the same length, if not you can get a shorter tail.
Trying to install any transmission other than the original (Rotohydramatic Model 10) involves a lot of work. Newer Turbo-Hydramatics (TH400, TH350, TH200-4R, TH700-R4) do not bolt up to the engine flex plate or bell housing, the drive shaft yoke will not fit, and the drive tunnel (hump in the floorpan) will need to be cut up and enlarged to fit these newer (and larger) transmissions. The original transmission for this car was known as the "slim jim" for good reason. It was unsually long and very narrow in cross-section - to allow a smaller drive tunnel and more footroom up front. Trying to squeeze a newer transmission under the car without contact with the floorpan doesn't work so well. There have been a few home mechanics who "made some room" by taking a sledge hammer to the floorpan to create enough clearance for the 200-4R trans. The adapters for the 394V8, the custom mangling of the crossmember and mount, and driveshaft all make it a frustrating (and expensive) project for the novice.
