Re: [AMC-List] Trans for 72 232 six (AW4 w/o EFI)

In light of the discussion, I thought you guys might find this site interesting:

http://awshifting.com/


I would look towards MJ's for 2wd AW4's.  I also have a source here in MI for the A340 that is rated
higher than the Jeep AW4 for $400 NEW (maybe less).  XJ wheelers here use them behind strokers.  I
bought one with the intention of installing into my XJ, but figured out that the trans wasn't my
problem.  I sold it to another XJ wheeler with a 99 (I think) and we determined that this trans
would be for the non-OBDII, as we found differences in the housings on 97-up XJ's.  We still used it
in his XJ, but it required mixing and matching parts from each trans.  The isn't a new one available
from this source for the later XJ's.  Sounds like the A340 that is available is the one you would
want, anyway.

Well, there's a bigger problem I suppose -- finding a 2WD AW4 in a Jeep.
Not hard to do in the south, but in northern parts of the country
(including Pacific NW -- anywhere there's a reasonable amount of snow)
they are pretty hard to find. But there may be a solution! The AW4 is
also known as the A340 in Toyotas, but it's the same trans. The main
trans body should interchange on the Jeep bell housing. The only
difference I've seen is that some of the Toyotas (specifically the
Supra) use an electronic servo in place of the TV cable. From what I saw
the servo mounts in the same location as the cable, and should be
replaceable with a cable. The valve body is calibrated differently, but
valve bodies will interchange. The only drawback here is you'd likely
need to buy a Jeep 4x4 trans and a Toyota 2WD trans (trucks and SUVs,
Supra and others rear drive cars with the I-6 or V-6) for all the parts.
If the servo can indeed simply be replaced with a cable then you just
need the Jeep flexplate and bell. I'd use the converter that goes with
the trans, especially if the trans and/or converter are used. 

MV Automatics in Australia supposedly has a shift kit available for the
AW4/A340. There's a couple places that will alter your valve body if you
send it to them in the states, but they won't sell a kit and charge
dearly for it ($575!!). I can see that for a racing trans, but a mild
improvement can be made by changing springs and possibly drilling the
plate between the valve body halves. You just have to know what you're
doing, and no one will tell! This would make the trans suitable for mild
360 V-8s. 

I found a site where a modified A340 is used behind a Lexus V-8 that
makes 218 hp/206 lb-ft AT THE REAR WHEELS on a dyno (that's about
280-300 hp at the crank -- http://v8cressida.com/). That's enough to
push the near 3461# car (approximate -- don't know how he arrived at
that figure) to 13.6 seconds @ 105.8 mph in the quarter and 0-10 time of
5.2 seconds -- with photos of a G-tech screen to prove it. Still don't
think I'd stick it behind anything more than a mild 360 in a light car
though. Would be perfect for a near stock 360 in a Hornet/Gremlin et.
al. though!!
