So assuming Aisan made their transmissions similar to Toyota's in both Manual & Automatic form...would it be reasonable to assume that perhaps the AR-5 or AY-6 could work with the 2JZGTE. Again this is assuming you have to make a custom driveshaft anyways...for someone without an MKIV Supra.
Again, just looking for some input...details follow:

General Motors used the AY-6 as RPO MV1.
Gear ratios:

4.15 2.33 1.53 1.15 1.00 0.79 3.67
Applications:
* 2004 Holden VZ Commodore

* 2005 Toyota Tacoma
* 2006 Holden VE Commodore

How does it's final drive compare to that of an R154??
Wouldn't double overdrives yield better mpg??
Makes me think it's better despite it being weaker---
Ratings can be over or undershot by a big margin sometimes as well.
Testing would be the final say on what it can hold up to..
I'm sure there's no data released for the R154 that says "good for 750 hp" either, but they can do it..
For instance, an NV3500 by New Ventures used in many chevy and dodge full size trucks are rated at 350 tq -- they are also know to stand up to numerous 11 second passes in a 4000 lb Dodga Dakota -- A boosted 4.7 making 500+ wtq -- in that case the trans is a copy of the Tremec 3500/3550 as is the W58... I guess it's just a better copy or something---
This sounds really interesting to me and I'd hate to just bash it b/c somebody "said" it's just as weak as a W58..
BUT......
After looking at the ratios, it doesn't look to be double overdrives, only single, and the first gear is super super low-- it would just turn into smoke with any kind of power in my opinion--
