I don't know for a fact but I would assume it would be the same transmission mated to all the 3.4 v6. If that is the case, maybe even the T100 too? Not positive if the T100 has a passenger or driver side transfer?
Honestly, I don't understand why you would SFA a V6 Tundra to begin with. Sorry, had to be said.
I question the value of that drivetrain in a full size 1/2 ton truck, especially when you add weight of heavier components to the truck. You will also be forging into unknown territory, with some people having done similar conversions on their Pre-runner 4x2 Tacomas but nobody doing the same thing on your truck.
You have a truck that is paid for and I assume good condition. I would consider selling it and buying something that already has most of the components you are looking for, i.e. 4x4 drivetrain.
Now if you are an above average mechanic and fabricator with tons of free time and a desire to do a big project then disregard and go for it.
Not sure if that helps or not.
