Is it possible to run duals on an 85 22re with stock auto tranny?
I searched but didnt find a clear answer

 

I think it is possible, but on the trails, in ultra low or w/e, your crawl ratio is gonna be huge and your breaks wont do anything

 

ditto, don't to the ultimate just do the doubler. I have heard with the ultimate the brake mounts ripping off.

 

Yes, but it's expensive. The only company that makes the adapter is Inchworm.

 

Whoa, with the auto and a doubler, you going to be able to idle up just about anything. That's going to be great.

 

In compound low, I can idle up just about anything with a manual transmission...

 

Im running a 3.4 into the auto (a340f) into dual inchworms with 5:1 in the rear case. My crawl ratio is 186:1 before you factor in the touque converter. which probably puts my ratio at about 400-500:1. Its rediculous.

Before that I was running the same t-case setup behind an a340h and a 3.0. It isnt that expensive.

I do however beleive dual standard cases (2.28/2.28) is plenty for the auto. I just couldnt pass up this deal I got on these cases. (built by Jim at Inchworm for the UA '06, 5:1, clocked 10*, twin stick, chromoly output...)

Heres some videos of the cases...I never use low/low/low much Im usually just in 5:1. But this whas when I first the cases and I was playing around.

low/low/low
Sorry for going so slow but there was 40 with a poor PS pump limping through the trail.

low/low/low
Here if I was in 5:1 I would have made that with out the hesitation, but I had no momentum due to the low gears.

BTW, my brakes will hold it in low/low/low. It has problems holding it on the street and wont hold pointed down hil, but on the trail they hold everytime.

 

I think the nice setup is the one that 4rnr has. I mean a "F" tranny so you can use a standard V6 adapter.

I don't have duals but I've swapped my R150F for an A343F (Almost the same that the A340F) and I love it.

the 343 is the fj80 trans right...

 

no i got the 343 in my hilux surf! push button 4wd on the tcase stick

 

As bigt says the A343F came stock on the 3.0TD autos, Hilux Surfs and Prados. The transfer can be swapped, I put my mechanical T-Case behind the A343F.

For what I've seen on my swap, the A343F and the A340F look almost identical, maybe some ratio difference but I can't tell.

Hmm maybe its different in the US?

There are a lot of different configurations of the a3xx series. And typically the differences are bellhousings, TC's, ratios, valvebodies, and outputs.
