Putting LC 3spd tcase gears into a 4spd case!!

[MD11Fr8Dog]

The part number for the idler cluster shims used when swapping  3spd tcase gears into a 4spd case are #36263-60010.  I threw those shims in and checked with a feeler gauge - right in the middle of the .004-.016 range!!  There are other shim sets as well - #36262-60010 and #36261-60010.  They are respectively thinner than the shims I used (not sure of the actual thickness).  I think they cost me about $4-5 a set from Toyota!

Also, make sure you use the orange bushings from the 3spd tcase, the 4 spd bushings are too thin.  See the pic below, from left to right - new 3spd tcase bushing, old 3spd tcase bushing, 4spd tcase bushing!  Big difference!!  You also need to use the spacer between the needle bearings from the 3spd.

Other things I did, I used the output shaft from my 4spd tcase (fine spline front output) and the front extension and housing (gusseted).  I used the 3spd rebuild kit from SOR, but the tcase topcover oil seal for the hi/low shifter in that kit will not fit on the 4spd tcase.  All the other bearings, gaskets, seals, etc were the same.

HTH someone down the road!!
