Difference in T-cases?
Hey I'm selling my transfer case out of my 1990 22re pickup, 5 speed W56 tranny. I got asked if it would bolt up to the V6 tranny (not sure what one he has). Are the Toyota t-cases pretty universal between the pickups?

uhhmm..i doubt it..V6 T-cases are Chain driven and the 4cyl T-cases are gear driven..likely different bolt patterns and such as well...and likely different input shaft sizes

Both trucks are 5 speed manuals. R150F and W56, I am looking at a chart but it doesn't say anything if the RF1A (W56 t-case) will bolt up to the R150F.
The R151F and W56 use the same t-case so I thought maybe the R150F would be compatible with the same t-case too.

Check with Marlin, not us. Nobody knows this stuff better than them. Looks like it will require an adapter.

the op wants to put the gear case behind a v6 manual tranny.
Marlin would know but I am willing to bet someone on here also knows .

check out the 2nd paragraph ..

"That mystery was about to become an area I understood much better when I located an R151F transmission from a 1986 turbo pickup. This poor R151 had had a rough life, as evidenced by at least two different colors of RTV on the seal surfaces of the cases. But the price was right, and if I am ever to fulfill my dream of swapping a V6 into my truck, I am going to need an R-series transmission! Plus, the advantage of the R151 is the way it mates to a V6 like an R150, but also mates to the geared transfer case (as long as you use a 23 spline input shaft) like a W56, my current tranny. And if I never actually do the V6 conversion, an R151 will be a definite improvement with its lower first gear and stronger design. Besides, my W56, though still serviceable, was going to need an overhaul before long, so why put money into a dead end? Roll back the dark clouds of ignorance, here I come! I bought the R151, and brought it to its new home."

Wow lets get things straight in this thread.
First: (btw all my comments are for the quoted text ABOVE each comment)
NO you CANNOT use a 4Cyl tcase on a V6 trans, without using an adapter kit AND changing the input shaft.
This and...
This are correct.
This is 100% wrong. The bolt pattern is completely different, not to mention the 90 truck is a gear driven case with a 21 spline input, and the V6 is a chain driven 23 spline case.
You merely read his sentence wrong. The r151 uses the same bolt pattern for the bellhousing-to-trans mounting as does the V6. Therefore, you can use the V6 bellhousing and put an R151F behind your V6 engine. Then, you have the strength of a V6 trans, with a 23 spline gear driven transfer case.
However, you cannot simply use a gear driven case behind the V6 transmission. If you could, there would be no reason for Marlin or Inchworm to sell/manufacture an adapter plate to bolt Gear driven cases to V6 transmissions.
So, recap. Can you use a 4Cyl case behind a V6 trans WITHOUT an adapter? NO. Does Marlin/Inchworm/AA sell an adapter to do so? YES.

is it late and I'm reading this wrong or what...
the advantage of the R151 is the way it mates to a V6 like an R150, but also mates to the geared transfer case (as long as you use a 23 spline input shaft) like a W56,

You are reading it wrong, and what the guy posted isn't really complete. The R151F (turbo) will only mate to a V6 motor if you use the V6 bellhousing. the R151F (turbo) trans also has a gear driven Tcase behind it, so you can swap a W56 tcase onto a R151F turbo trans IF you swap the input shaft to a 23 spline. You CANNOT put a gear driven case (from a W56, G52, or R151F) behind a V6 trans (R150F) without an adapter. Again, why would Marlin/AA/Inchworm bother selling an adapter if you could just simply bolt the case on to a V6 Trans?
