I have a question about mating my 1uz to the fj80 or fzj80 land cruiser transmission.

A440 or the A442.

I am finally able to do my own 1uz swap after doing many for customers. The difference with mine instead of using the stock lexus transmission, the A340h or e, or even converting to a manual like I have done for others, is I am running fzj80 axles. And thought it would be cool to run the 80 series transmission and tcase, for strength and proper drive line alignment.


correct me if I am wrong. I am going to need the bell housing from a LX470, or a 100 series that came with the 2uz and the landcruiser 4 speed auto. This would allow me to use my 1uz and the 80 series transmission. Or does the A44xx transmission have the same bolt pattern as the A340 on the transmission side, so i could simply use my stock 1uz bell housing and bolt it to the A44xx transmission?

Hope that makes sense,any help would be appreciated.

It make sense but I just don't know if anyone has tried it. That tranny may not communitcate properly with the 1uz ECM.

yea dont know about that combo , but if your gonna stay auto just use the lexus .. then you wont have to worry about the ecu and tranny situation.. wait does the tranny off the fj have separate ecu for the tranny?

I believe the A440 have a separate ecu but I am not sure about the A442. The landcruiser stuff is new to me. I really want this to work. I think I am just going to buy it and see what I can do. If it doesn't work.. then I will have a tranny and tcase for sale

I'm pretty sure the Landcruiser t-case is an offset rear output.

so did it work ? what did you end up doing here . i,m starting a similar project and would like to run a offset transfer behind the 1uz..
i wonder if the 1uz ecu would control the 2uz auto.. so as to just run the 100 series auto and offset transfer behind the 1uz with the 1uz ecu controlling both .
