The R154 transmission used in the MKIII Supra Turbo, Toyota Chaser Tourer V, Toyota Mark II Tourer V, Toyota Cresta Tourer V, and Toyota Soarer turbo. The supra was the only model I believe that was sold in the US. BotXXXXX XXXXXne is you don’t have a lot of transmission choices, the few you have in the US are the factory R154 transmission. or adapt to another type of transmission. The problem is the adapters are expensive. The two adapters I have seen adapt the GM automatic type transmissions (great for drag racing), or the other adapts the 350Z Nissan transmission. There isn’t any cost savings here, just flexibility on what type transmission you can use. I have a few links for you, the link HERE is for the adapter for a GM transmission, and the link HERE scroll down to the 7th post, some info on the Nissan type adapter. For the Nissan adapter you would probably have to join the forum, and see if this guy is still offering them. If you have any more questions, as always, I am here to help. Good luck with it, have a great day, and Thanks for using Just Answer.
