Is there a difference between a 1991 22RE 4wd 5 speed transmission and a 1992 22RE 2wd 5 speed transmission?

I have a donor engine/transmission lined up but it's 2wd and in searching I can't figure out if it's different. Thanks!

 

Find a 4wd transmission, with a 2wd transmission you are looking at either losing 4wd or a heap of unnecessary work.

 

Similar ? So I'm subscribing.

Can the 4x4 tranny go into a 2wd truck if you remove the tcase and swap tailhousings.

Hey legend. If you are needing a 4x4 5spd. I have a w56 with tcase attached. I bought a truck for the motor and haven't yet pulled the trans and all out yet if you are interested. where yah located

 

I'm going to assume the output shafts are different (they definitely look longer according to Google) since on a 2wd the driveshaft is solid and slips on the 2wd output, whereas the 4wd shafts bolt to flanges on the transfer case. This alone would probably mean mating a 2wd trans to a tcase isn't gonna be easy.

Lots of things about these transmissions are similar. It might be possible to do something like say use the output shaft of a W56 in a W55 that's had it's tail-housing removed and mate a transfer case to that, you'd end up with the gear ratios of the W55 though.

If it's an R series transmission, I think the R150 can also use parts from a R150f (4wd R150).

 

Might bolt up to the motor, but the driveshaft lengths will probably be in-congruent not to mention you wouldn't be able to put a transfer case on a 2wd tranny so no 4wd.

If it's possible it will likely end up being more costly, time consuming and difficult than just getting a 4wd transmission.

 

Damn, that's what I was hoping to avoid. My tranny's starting to go (the 3rd and 5th gear whine) and my engine burns oil on inclines so I was hoping I would be able to buy this engine/tranny for $650 and fix all of my problems, guess not though.

BigSwole - I'm just outside of DC so I don't think a 14 hour drive would be worth it for me. Especially since I would have to do it in my falling apart truck...

How can I tell which transmission I have? Are there any others that I could swap in it's place? I'm used to Jeeps where just about anything will bolt up.

 

With the power of Marlin Crawler and the info in your sig...

Your transmission is a W56-C. Which come attached to '89-91 22REs.

 

Couldn't it also be one of the G transmissions?

 

Those mostly came mated to 22Rs, unless your truck's PO swapped one in you should have a W56. Unless you truck has/had ADD, then it might be a G58

Thanks! That really does explain a lot. Also it's nice to have a reference point to the transfer case and axles.

 

Yeah it does need brake fluid.

 

G vs W series is simple to identify. Fastest way is look at the shifter cover. W is 6 bolt, G is 4 bolt. R series (v6, and turbo trucks) are also 6 bolt.

On the 91 pickups, the transmission code it came with is on the door sticker. Generally 22RE came with W56, but W55 is possible. For the 22R (carb) engine, I've seen W46 (4 speed version of W56), G52, and W55 all as factory units. 1 Tons might have gotten the W56 for it's lower first gear. This list expands the whole 86-95 pickups I've had so far.

For the 2wd vs 4x4 transmissions, the main bearing plate forward is the same on most models within the same era (like W56-C mentioned above). The difference is the output shaft (gears have to be switched over from the 4x4 output shaft to your 2wd output shaft if your gears are shot), and the rear case half of the trans is setup for bolting the transfer case to instead of the slip yoke style drive shaft.

If you wanted to bolt in the 4x4 transmission w\o the "extra" work, it would probably be possible, but you'd need a custom drive shaft, the transmission mount points should be the same, transfer case might be a headache to make room for though. The only benefit I could think of it all from this setup is a "low range" or pre-prep for a solid front axle swap. I suspect the rear 4x4 drive shaft would be the correct length with this setup. Never read about anyone doing this, but in theory it seems possible.

$650 seems a little high, but my area the 22r's run around $250-$500 depending on miles, and the W56 4x4 with transfer case runs around $200 separately, together it seems like it would be a discount for buying in "bulk". If you do buy a used engine, be sure to check it over well and change servicable parts before installing it (timing chain, rear main seal, rear soft plugs if they are rusty, etc).
