difference in transmissions?
I have a 1989 22RE 4X4 pickup (W56).
I also have a 1995 3.0V6 4X4 pickup (R150F).
What's the difference between the two transmissions? Is it just transfer case shifting (top - forward) or is it something else? Is the R150F an improvement over the W56? If the difference is just bellhousings, can't you swap them?

I would stick with the W56. The gear case is much stronger IMHO and gearing can be changed if you ever want to upgrade for wheeling.
However, TC is correct you will need an R151F bellhousing (turbo truck) to mount the V6 trans/case combo, as well as having your driveshafts redone.

I think you mean gear drive case.
I disagree about being stronger, but can't argue about the lower gears... chain drive cases are holding up just great behind 4.7 crawl boxes in supercharged Tacos making way more power/torque than a 22RE will ever dream of ...

W56: Rev:-4.091
1st: 3.954
2nd: 2.141
3rd: 1.384
4th: 1
5th: 0.850
R150F: Rev: -4.220
1st: 3.830
2nd: 2.062
3rd: 1.436
4th: 1
5th: 0.838
The R150F is stronger. When Toyota introduced the Turbo Truck and 4Runner
in 1984, they developed the R150F, a 4WD version of the R150. It is typically connected to stronger differentials as well. It was a natural carryover to the V6 models in 1988.

The R151 is stronger and has a significantly lower first gear - but due to that (per Marlin) it will not shift as nicely as the W56. The newer R150s shift better than both and share the strength of the R151. The chain transfer case is not in fact weaker, but the geared case can be regeared which is huge. A geared tcase can be bolted on to any R150, however, with a Marlin adapter.
If I had it to do over, I might have gone with the R150 behind my donor 1996 instead of the R151, and just used the adapter for a Marlin Ultimate. But it works fine and I like the low first when towing and in sticky situations wheeling.
