Duh, I already knew that. You still didn't answer my question.

At the end I said I havent looked into it yet so who knows. Now ive looked into it a bit and I know now that the VF3AM multi mode transfer case does bolt up to the R150F, but I havent gotten much more info than that yet.
 
Not much of an update as far as actual progress, but I did find a manual wiring harness and ECU out of a 98 4R from a member here. That will make the confusion of wiring a whole lot easier. But that will also do away with any hopes for using the multi-mode xfer case.

It is a bit of work, but ill be about $750 into the swap when its all said and done, and that's about half what it would cost me to build my auto like I want it. Also, ill be 1 of 2 limited manuals that I know of. All I need to do now is order a clutch and get my buddies together and we can knock this out in an afternoon.
 
So,you are losing the AWD and ability to lock the center diff? I'm not so sure it's an upgrade as far as performance but if it was just the simple auto tranny swap I'd do it but to lose the multi-mode I'm not so sure.

AWD and locking the center locking diff are the same thing...

I dont use AWD really, Im either in 4L or nothing. I used AWD this past year during a pretty nasty winter, and found id rather be in 4HI than a primitive AWD system. With 220k on the trans and converter its only a matter of time before it craps out on me.
 
Nah nothing yet, its finally getting warm out and Ive been taking full advantage of the nice weather. My autos still doing really well, but I'm pretty excited for the manual.

Record speed if you do it that fast.

BTW, which ECU did you purchase? If I were in your position, I'd use a 99 SR5 4x4 M/T ECU and wire the transmission using OEM diagrams. It's worth it to have a properly wired truck IMO.

The rest is pretty straight forward... much easier when you don't have to completely add in 4WD altogether.

Good luck with the swap.
 
Not to toot my own whistle, I think that this swap would be pretty straight forward.

Assuming he got the drive shafts, it should all be bolt in. I wouldn't worry about switching out the ECU. I would trick the stock ECU into thinking that it was in N. I wouldn't worry about a starter interlock or clutch safeties either.

I would hook up the reverse lights and roll with it.

He could keep the AWD but he might have to get drive shafts shorten or lengthen accordingly.

I am going to be devils advocate. I like the automatic transmission. It's easy, fun to drive, smooth and pretty reliable.


It is a tough dissicion to make. Take a perfectly good running 4runner and break it apart to make some thing new. I myself had this struggle not to long ago.



The OP needs to sell the Auto tranny first, then do the conversion. He could let the prospective buyer test drive the tranny first then he feel confident about buying it. Once Sold, he could do the manual swap.

So you are saying that the Multi mode case will still function with a manual swap? And all dash lights will work correctly, assuming the ecu thinks it is in neutral? What about the ADD? What wiring does this swap require?

I'm confident with the entire process aside from the multi mode mating the the manual correctly and the wiring side of things. I'm trying to keep my original t-case and ecu and have everything function properly but I keep reading conflicting views to whether or not it will work. Thanks
