Have a 1995 Toyota Supra twin turbo engine with automatic trans that I plan to install in my 1999 Cherokee 4 x 4. Question is - can the Toyota trans be modified with parts from the AW4 to fit my transfer case?

I have no earthly idea, but I sure am interested. That is a sweet motor.

That should be a AW4 behind that Yota motor. I think Toyota has a different name/classification for it. Then again I'm not a Yota fan so i could be wrong!

It's called the A340. I think you would need to replace the output housing, maybe the shaft too.

AW4 and A340 are the same trans so It SHOULD bolt up! Bolt an AW4 to it and call it a day! I agree with everyone else in saying, Thats Badass and you should post a build thread! :yelclap:

Thanks for the response & encouragement. I currently have a TE-60 turbo robbed from my Grand National on the XJ. It runs OK and I could continue with modifications but the 2JZ can make ungodly power for much less money. (My GN looks as stock as factory, but with the Stage II motor is making 748 hp, is so much fun to drive).

The 2JZ will bolt to the AW4 so I can install it and make it run, just don't think the AW4 can handle the power. Could have the AW4 built, just hate to leave a good 2JZ trans sitting on the floor.

Sure do appreciate you guys sharing any ideas you may have, even if they don't make sense, it might trigger a new thought.

The AW4 can handle the power, just get a fresh un-abused one. I have heard some big numbers handled by the AW4.

Yeah I had heard that myself. OP, How much power do you plan on pushing?

With the twin turbos I can about 400 hp. I plan to remove them and go with a single one, other mods will be necessary as well, I think 550-700 would feel good in an otherwise stock XJ 4 X 4. Already have a 3" downpipe to tailpipe exhaust system and fuel management system.

Had one of these engines in my 98 GS300 Lexus, single turboed it along with other mods, was a real sleeper, expecially with the factory exhaust quietness. Even the gas mileage was cool.

Got to iron out the trans difficulties then attack the engine management system on the XJ.

Thanks for your imput and ideas.

im actually looking into this trans issue also im swapping in a lexus 4.0 four cam 32 valve v8. the trans appear to be the same trans as long as it is rear wheel drive i am not seeing any issue with this i looked into upgraded trans for my lexus transmission and it list the AW4 on the same list as mine. so go for it!!!

The aw4 can handle lots of power. Somebody on here ran it behind a 401 IIRC. Ran 12.5s with that tranny.
I think you can swap the valve bodies between the Jeep and the Toyota versions of the the trans for firmer shifting.

This project is going to be amazing.

Novak does not appear to have much confidence in the AW4, in reading their descriptions on auto trans, they seem to prefer GM automatics.

The toyota auto trans can only handle about 400-450whp. I would try to use the aw4 and see what happens.

thats because they make the adapters for the GM transmissions. Don't get me wrong, they are a great company, but the fewer different adapters they make the larger their profit margins.

they don't favor it as a transmission to swap to if you would need to do extra work. Bun in an application like this where no mating adapters or mounts are needed, then it should be a cinch.

level10 transmissions can modify the Supra A340 to handle more than 1000 hp, maybe they can modify the AW4 too, it's basically the same transmission, a guy around here is installing a 2JZ engine in a Samurai (yep, a S A M U R A I) with the Supra tranny and the tailshaft from an AX15, here's a link to his project:

Wolfpackjeeper you make a good point. My thoughts thus far is to continue with the AW4, since it's already in the Jeep. But even now having just added a turbo and exhaust it flair shifts going from 1st to 2nd. Other shifts are good.

Maybe after getting the vehicle running (hopefully in Jan) and it doesn't shift good enough I can go after a better one. But it should be good enough for cruising as this is strickly a highway vehicle.

Thanks again for your thoughts.

what rear axle do you plan on running with that? if i were you i would install some frame stiffeners too if your expecting 500+ hp. i cant wait to see this, did you see the new super street with jamies supra in it? i had the pleasure of seeing that thing run at norwalk, the turbo is HUGE. i thought the hx40 my buddy and i are running on the summit was big...


i cant wait to see what you have in store for this xj. lets see some pics of said GN!

Look at page 108... not sure how many of you can read spanish...

http://www.twistedandes.com/foro/showthread.php?t=11172&page=108

Si lo habia cachado, pero ando en busca de una caja completa fundida para cambiarle la cola y usar la reduccion planetaria, ya que es kit debe usar el eje original, lo cual lo hace demasiado largo para mi jeep.

La caja puede ser Toyota o una AW4 que venia en los Cherokees, son basicamente la misma AISIN.-

I haven't had spanish in a while.. but I read... "the transmission in the toyota is a AW4 that came in the cherokee. They are basically the same Aisin.

a friend of mine that owns a transmission shop once told me that if it wasn't for GM and Chrysler that transmission shops would go out of business. Don't get me wrong a GM or Chryco trans can be built up but so can Toyota and the AW4 is a very good transmission.

Jeep has a 3:42 rear gear, will add a locker. Have not seen Jamies Supra, not sure where to go to see it. Import Performance must really be good, they have some sporty prices. I'm satisfied with trying the AW4. Can always swap it out if necessary.

Would like to post some photos of each of my vehicles but have not figured out how. It's a pretty shabby collection but I do have some photos saved.

You *may* need to use your AW$ bellhousing and input shaft, but other than that it should all work.
Oh and uh... PICS ASAP :D

I think it's gonna require the Supra tranny housing with several components back, including the last planetary set of gears... but between two whole transmissions, I think it will work. TT Supra valve body mods should be made as well.

If you are using the auto tranny (A340e) that should have come with a JDM 2JZ-GTE, I know 100% it will work.

Exhibit "A"
http://i54.photobucket.com/albums/g93/ckassem/XJ%20Jeep%20Cherokee/Jeep22HybridTransmission7.jpg

This is a modified Toyota A340e that, thanks to a donor AW4, now bolts right up to a 2JZ-GTE using the stock bellhousing and torque converter, and then to the stock NP231 transfer case in the Jeep.

good idea, but not much space in an XJ to do it, and requires more crossmembers and framing. It also requires adding seals to the input of the transfer case and output of the transmission.

child9
January 29th, 2011, 09:29
Seriously? Well that would explain why I'm not doing it that way. :) The 2J comes with a "better" version of the AW4, so the simplest solution (IMHO) is to marry it to the NP231 and be done. Should bolt right in. My only worry now is that there are about 2" between the back of the 4.0 and the bulkhead. The 2J bellhousing is a half inch shorter I think, so that leaves precious little room for the differences between the 3.0 and the 4.0 block/head dimensions to the firewall. I'm hoping it fits ok, so all I have to do is set it's height and build the front motor mounts to hold it there. I want to never touch the transfer case or transmission mounting points.

I think the OP owner is gone on this, but I am not.

Probably a good plan.

On the setup you have, the stock crossmember connects to the 4wd adapter housing on the tranny, and the transfer case and transmission both bolt to that. No transfer case mount per se.

child9
January 30th, 2011, 05:26
Ah yes, this is true. Either way, I want the transmission mount to dictate where the engine sits in the engine bay, and I want it to work WITHOUT a hammer, lol. We'll see March 18th.
