The A340F A/T in my KZN-185 is on the fritz, so I am thinking of doing a manual swap. There are a lot of write-ups for doing that on a 3rd gen 4runner, but I haven't yet found anything comprehensive for doing this on a Surf.

The first, threshold question I am trying to figure out is can / should I mate 1KZ-TE to R150F transmission that the North American 4runners came with, or do I have to necessarily use the R151F?

As far as I can tell, there are at least three differences between the two:

1. Gear ratios for the first two gears (R150F: 1st - 3.83, 2nd - 2.062; R151F: 1st - 4.313, 2nd - 2.330)
2. not sure, but it seems that R151F uses a dual mass flywheel and R150F doesn't?
3. the rear drive shaft is different between KZN185 and VZN185 with manual trans (front drive shaft is the same). I am not sure if the difference is just the length or something else as well (I would guess that the KZN would be shorter since transmission mounts further back).

Would appreciate anyone's input
