i read that i can swap out the 21 spline for a 23 spline, so if the 2wd tranny is a R151f then im set.

i bought a turbo 2wd extra cab and i'm planning on swapping that engine and "R151f tranny" into my 1985 4runner 22re. i will want to swap all my regular 22re stuff to the extra cab so it can run. i will put the w56 transfercase onto the "R151f" so i'll still have 4x4. will the W56 tranny work as a 2wd tranny? marlin, you are the master of toyota transmissions, please help me before i dig a hole i can't climb out of...
