Outer Limits 4x4 Board

I have found some where i can get a Vit 4spd auto for around the $600 mark. Only problem is the dude who is trying to selling is telling me its an asian-warner style box(nfi). he had no idea if it would bolt up to my 1.6 baleno motor in my sierra. and sorta borked when i asked about the wiring harness. Does any one know any thing i might beable to asking to figure out if it will be usefull to me.

MightyMouse and CJ have more information on this than me, but yes, it is an aisin-warner box.

Mugginsmoo is doing this exact swap now. (Baleno G16B/AW-4 into sierra.

If it is from a vitara then yes it will bolt to your baleno G16B

You will need to use either a Toyota hiace rear output shaft and tailshaft housing, a vitara transfer case or fabricate a short tailshaft housing to suit.

If you want it to shift properly, you will need the harness and TCC (tranmission control computer) from a vitara, or altranatively, you can use something like the fully manual shifter from www.awshifting.com

There is a lot of other more technical information such as torque converter lockup etc controlled via throttle position, VSS etc an dothers here will provide more information.

PS certain models of this auto ran behind carby motors and even diesels so there are fully standalone versions that don't need a reference from the computer.

they are a good gearbox but if I were you I would try and do it with the right control module as I think in anything that is not a full on bush car shifting manually all the time woudl get old.

does $600 sound about right?

Depends. If I had an otherwise fine vitara with a blown auto it would be cheap- it will be a bolt in and out conversion.

If you don't have the time/skill/$$$/patience to work out how to wire it to shift properly, and can't work out how to sort out the tailshaft, then $600 is a lot of money for 40kg of scrap metal.

I;m not trying to be a smartar$e. I think that $600 is about the going proce for one in decent nick. As a conversion into a sierra, you will be up for more money to get it sorted, so make sure you take that into account.

MightyMouse is putting this gearbox behind a non-native motor (daihatsu) so he has had to sort all the wiring etc to make it work. He is very clever though (except for the buying a Daihatsu in the first place) so he doesn't see a barrier to something working when we might.

Also as an aditional question related to this, are these much shorted than the manual vitara gearbox?

They are longer by about 1.5." When the 4 speed auto's went into vitaras the crossmember position and configuration changed dramatically.

The old 3 speed vitara auto is effectively the same length as the manual.

If you are a SWB sierra and want to keep a useful jackshaft, you will have to make a custom tailshaft housing.

If you are running dual transfers with a vitara manual right now, you will have to move everything bcak about 1.5". This will make your rear driveshaft pretty short. tHe trans tunnel will need widening too.

If you are up for some fab work, they are a worthwhile swap. they are a reliable and strong auto, but they are not anywhere near as easy as the three speed auto to fit into a sierra.

Maybe tell us a bit more about your setup?

Steve.

ok well i have a swb 92 sierra with a 1.6 baleno motor in it. i currently only have the standard gearbox but, I would like to go to dual transfers ie vitara gearbox w/transfer and sierra tranfer behind it. problem being the whole settup like that ends up a little too long to be practical. Fab work is not a bother but there is only so much room in a swb for all the stuff. The other option is to run reduction gearing in the sierra transfer but i really dont want to reduce my high range from where it is now.

steve.

forgive my ignorance but are you saying that the output shaft and housing from a hiace auto will mate up to a 4 speed auto?
And if so what years?

Stu

Um, early 90's Hiace ran an AW-4 with a very short rear tailshaft housing, however, it is too long to work with any sort if useful jackshaft and a stock transfer case position.

The "shortest" option is a plate talkshaft housing and a bearing block and seal. I know the trimatic uses the same output spline as a 1.3 sierra gearbox output so it is pretty easy to make a tough three speed about 1.5" longer than a sierra 5 speed, but the 4 speed is a bit longer again so it is marginal to a jackshaft.

Lots and lots of cars have used AW-4 series autos, including jeep cherokees, lots of toyota product and suzuki. Not everything is interchageable and it can get pretty messy to fnd the right parts.

Again, CJ and Mightymouse might be able to offer more info.

in the duel transfew setup, vitara man 5spd, does the std sierra transfer stay in its factory location???

I'd be trying for half that without the computer and loom. At $600 it's not a bargain in my opinion if you doing a conversion. If it was to replace one already in a car and it was your daily driver so you needed it now then maybe $600 isn't so bad. I'd keep looking.

For a Vitara 4 speed Auto Gearbox, I think that $600 is on the money. I just had one rebuilt and investigated 2nd hand options which came in at about $700-$750. I elected to have mine rebuilt which cost about $1850 installed. This was not much more than what the 2nd hand box would have cost me installed and I got a 20,000 km warranty on the rebuild. The Gearbox shop reckoned that he Aisin Warner box was a prety good box. Good luck with the conversion if you go that way.

well i got one for sale tailshafts auto gb for $350ono 40thousand on it

...and I got one for $240. Yiou need to shop around.

One day your gonna wish you never sold that.

Just my 2c

Steve.

y i want it out of the shed

Um, because it is about 1million times better to drive an auto offroad than a manual, especially if you are planning heaps of power.

Steve.

you all got ripped off,

I paid $200+freight, with computer, torque converter, shifter and t/case

X a billion gazillon trillion, you're gonna want that back

Agreed, an auto is better to drive off road than a manual. In a trail type car, i'd rather have a manual.

Nope it has to come back. depending on how you do it, not necessarily very much, but a bit all the same.

I have seen them done in stock wheelbase SWB's but it always looks marginal to me.

Steve.

looking at the fit, i doubt that there is enough room to fit the AW4 into a SWB. and the tunnel is WAY too narrow in the 1.3L
The AW4 takes up a lot of space in the LWB,

ok bumma. well not really just an excuse to buy the transfer brace

i also have a body lift, obviously that will help with clearance but will that make it so i DONT have to cut/ bash my tunnel to make it all fit (not that im afraid)
thankx

Manuals go into the tunnel alright as far as I am aware.

If you really want duals (which I think are a bad idea on the $$$+work vs outcome equation) the ONLY way to do it IMHO is with an OTT kicker.

Steve.

i have a vit motor and gearbox sitting around doing nothing, i got a wt sierra that i want to put 31s on so thought id let them all mate up and hopefully have fun...

OTT kicker??
