I am not certain, but I think you are talking about the JDM version of the R154 (is there a difference?? probably not). I dont have a JDZ so I will let someone else answer it. The only thing you have to be aware of is that you do not want a W58 and if its the warehouse you are buying it from that I think you are, they will know if it fits. (I am in Calgary as well) Pretty sure the R154 is universal and the bell housing as well. Oh.. and you may want to have the boys at Dominion give it a lookie-loo after you buy it (you only have a 90 day warranty if its what I think you are buying). They are a great bunch down there (Dominion transmission just by Chinook on 58th)

As well, you may want to chat with Reg and the boys at RTCS about the shifting forks as well. (people here can correct me if I am wrong). Apparently the only bad portion to the R154 is that the 1st and 2nd forks are prone to bending. They have an aftermarket fork set that you may want to look into. (will know more about that when I get the car back in about a week or so)

Again, I will let someone who knows for sure answer it but from everything I have read, its the same trany on both. I am a Supra owner, not a mechanic.

The R154 transmission (the stock 7MGTE 5 spd transmission) can be used on M blocks and JZ blocks. If the transmission you have did come from a 7MGTE, then you will need a JZ transmission bellhousing to mount them together.

You will also likely need a different driveshaft, but I don't know for sure if the same differences in 7M supras apply to 1JZ supras.

Hahaha funny thing,my auto seal just went, and i got it towed to dominion transmission, your right they are really great guys, im going to see how much it will cost to do the swap,
maybe it will be less or around the same to swap the transmission to standard other then fixing the automatic transmission.
