How do I identify Transmission/Tcase/Diff version number?

[MalcolmY]

1991 FJ70 3f (Saudi Arabia or GCC)

Do I have H41/H55/H151, GBK4 or GBK5?

This must have been asked and answered before but I don't know how to find those posts. IS there a guide for any land cruiser?

(My transmission is bad and needs work. I have to buy some stuff and I'm stuck wondering which Terain Tamer kits to buy).

Info is on the VIN plate, under hood.

Looks like this

Well, an H41F is a 4 speed. An H55F is a 5 speed. Do you have a 4 speed or a 5 speed?

That should be simple enough.

You do not have and H151F. The 3F did not get that transmission behind it. Only the H55F in 5 speed flavor.

So that should clarify everything for you by process of deduction.
