"Resistance?" What do you mean by that?

The AW4 is actually a fairly solid box, and tolerant of abuse. It was used in the Supra (turbocharged I6,) RWD Toyota van, Toyota Pickups, and some Lexus models - so check the Toyota world in your area for performance mods.

There's only one vendor I can think of offhand that handles AW4 upgrades here - Level Ten (www.levelten.com,) but I don't know if he'll ship to Europe. No harm in askin', tho...

Good luck!

Yes, please!

The AW4 is usually compared rather favourably to the THM700R4, so you'd be better off sticking with it anyhow.

What Diesel did you use?

Re: aw4 performance kit

I don't know if they'll work for you (being that I don't know the bellhousing pattern of the VM engines, or what adapters may be available to you,) but you could look for a GM THM350 or THM400, Chrysler A727, or Ford C6 as well. They're older, all are three-speeds, but they're tough enough to use behind racing engines (I used to build THM350's, THM400's, and A727s all the time for bracket racers.) All are solid, although I do prefer the GM or Chrysler box.

That may be cheaper than a four-speed (which is what the THM700R4 is,) or other newer box. Also, you'll have to watch out getting a THM700R4 anyhow - I typically suggest you try to find one made 1990 or later, as the earlier ones are generally only fit for scrap metal.

Re: aw4 performance kit

the IPT answer me!
the give me this options:

We can take care any of your needs with your transmission and torque converter,you have some options.
1) IPT Performance transmission re-build kit. $589USD
2) IPT Performance torque converter $489USD
3) IPT Performance valve body $575USD plus core charge if we use one here.
4) IPT Performance Fully built transmission $3275USD plus a $875 core charge if we use one here.

now i can spend only 600$..wich part do you suggest me to upgrade the aw4? only to improve the resistance, not the speed of shifting..i think i have 45 kgm of torque..
also i read in your forum that is very important the cooling, i will intstall a radiator of oil more big than the original..

thanks

Question - is it "Diesel" or "Greasel" as you run it? A couple of years ago, they figured out how to crack Diesel into the lighter fractions that make gasoline, creating an artificial Diesel shortage and driving up Diesel prices here (which means they finally passed gasoline by a decent margin.) Is Diesel still cheaper for you over there?

(Greasel - also sometimes called "Biodiesel," "Greasel" is treated Waste Vegetable Oil - WVO - that is used as a compression-ignition fuel. Just in case the term hasn't drifted over to you yet...)

Re: aw4 performance kit

http://www.ifsja.org/forums/vb/showthread.php?t=964
here there are some picture..
now the price of diesel in italy is very close to the gasoline´s price (1,4euro/litre)..
i have heart that i can run with 50% of vegetal oil in the convencional diesel, some day i will try..
i still have installed the manual gear (T176), at the end of next mount i (my friend/meccanic..) will install the automatic trasmission..
to install the aw4 we will use the parts (i don´t know the name in english..flangia d´accoppiamento e volano) of the grand cherokee 1999 that in europe had the VM 3100 and 44RE trasmission..
i spoke with the constructor of my engine and he said that i have 450 libers feet of torque, i´m thinking to buy only:
1) IPT Performance transmission re-build kit. $589USD
do you think also the IPT torque converter is necessary? what are the difference without this?
thanks
