What is the Jimny Auto

[greg]

Hey Folks,

Thought i would throw this out to you peoples since i'm not getting a lot of co-operation from the gorillas i've spoken to so far.

1. Is the Jimny Auto a Vitara Auto with a different tailshaft housing (i.e. a divorsed x-fer case)
2. Will the Jimny Auto connect up with a Vitara Block in the same fashion as a Sierra 5 speed box will? i.e. they are both G13x's
3. Is it confirmed that the Jimny Auto box is the same length as a sierra box? i.e. could you rip out your current 5 speed and drop in the jimny auto box?
4. will the tail housing from the jimny swap over onto the tail housing of a vitara gearbox? i.e. could you use it to convert a vitara auto into a divorsed x-fer case.

Thanks in advance,
Greg

Greg i think that the Jimny block has the same pattern as a Sierra. Therefor I think the jimny auto would bolt up to a sierra.
This is only speculative so don't shoot me.

You can Build one at home !!

You will need Two piece of burnt vegimite toast and a coke can 200mils of vinegar and 100mils of treacle,

Place the above ingedients within the coke can and heat briskly on a hot plate , Viola !!

This is only a replication but gives 99.9% performance of OME ,
Foul smell and no foward progress........




Aparently The four speed auto ratios are :

Hey greg is this a one off post or are you back?

I think he'll be on randomly, i have set him up on my PC so he keep up with all the web-goss, he also has access at his parents.

[muppet_man67]

whats the update on the new zook? Is that what the jimny auto would be for. Is he going to build it or have it as a parts car?

There is some discussion ATM but will be EFI, most likely Vit pref. auto and thorax at a later date

So assuming the above is correct - it should be able to be bolted up to a Vitara 1600 block too (using the same techniques as used when attaching a sierra 5 speed to a vitara block).

Right?

Then it's just a matter of working out how to send the jimny auto the required signals to change gears etc.

End result = 4 Speed Auto, Vitara 1600 EFI and a complete jackshaft in a swb sierra

[antt]

do it greg, than if it works you can come install one in mine aswell

How do you figure that Greg, isn't the Jimny is a longer wheel base than the Sierra?

[greg]

so folks,

dare i ask the big questions then:

1. is there such a thing as an auto jimny with an M13 engine?
2. is the auto box the same length as a manual box?
3. is the x-fer case a divorsed transfer case? - i heard to day that it wasn't but that sounds wrong to me since people are able to put rockhoppers and similar gears in once they swap out the chain driven x-fer for a geared one right?

And, the big one...

Is there anyone in melbourne with an M13 and an auto that would mind if i came over and a measuring tape and did some checking? (no pete, not that sort of measuring).

thanks,
Greg

1. Yes there is such a thing as a M13 powered Jiny with 4 speed auto.
2. Probably. If not i'd say it would be close.
3. Yes
4. No

Here's the bad news. I have it on good authority that the M and G series engines are not compatible with regards to transmission bolt patterns. I have asked this question before and have been told they dont bolt up. How far different they are is unknown.

If you want to quiz someone in the know give Rod Reardon a call at 1 Stop Suzi Shop (Gold Coast).

[Dozoor]

Why not just use the early vit auto greg ?
They are only a three speed , But its aperantly the same belhousing as a garden variaty trimatic with a diferent rear output andcase to siut transfer so you whack the early vit three speed auto bell on to the vk trimatic make a jack shaft from a holden >< sierra shaft >

used to be a guy on here that ran a star fire four /tri matic into vit transfer - to sierra transfer - /\ can,t understand why more people havn,t used this motor for conversions, 10kw extra makes its power dooown low 1.9 ltrs -- prob biuld to 2.2 ltres with stock red bits,
and parts as Cheap as chips . pickup a motor and box for price of two bottles of jack

Problems with using some autos for conversions are fluid starvation on steps ect -- a real pain in the coit. you can over fill them a bit but usually dosn,t fix -need to make custom pan and pickups

[Drewfus]

usless trivia...

A while back I wrecked a early corrolla for it's 4K engine. It had a stock auto behind it, a trimatic. Ended up swaping for a 4 speed as I was to lazy to cut out Sierra tunnel.

Trimatics are everywhere.......

As mentioned, useless trivia.

[droopypete]

thanks for the info folks... i'll keep coming back with more questions as i come up with them

cheers,

While I was in a Suzuki spare parts dept. I asked if the driveshafts were the same length on the auto and manual Jimny. They list two different part nos. for Propshaft No. 1 while only listing one part no. for Propshaft No. 2 and one for Propshaft No. 3 but without a VIN couldn't tell more than that. Didn't have an auto on the yard to compare to the manual.

[Badooky]

just spoke to the guy at suzukisport in perth and he tells me that the early jimny that has the g13bb engine should bolt up to a g13a, g16a or g16b, the latter to needing the adaptor kit. the later jimny with the m series engine is very different as previously stated. hope it helps

[droopypete]

I had a measure of an auto Jimny, auto is about 500mm bell housing to uni cross (about the same as a 5 speed)
Jack shaft is about 350 cross to cross.

And bit of useless trivia, my guts will not fit under a Jimny chassis rail if it has standard size tyres

interestingly i tried to get under a jimny at a wreckers and couldn't get my guts under one either.

though i should point out that it had destroyed rims and pretty much no tyres either

Sounds like a nice plan but 2 questions;
1/ how would you control the electronic shift of Jimny Auto unless you use a Jimny ECU and the Jimny engine sensors on a Vitara motor (or just use the Baleno/Cultas G16 EFI distributor-less motor)

2/ will the extra ponypower & torque from the 1600 strip the internals of the auto? (i have heard stories that it was only designed for the Kea 660cc class and up-rated to handle a 1300 motor)

I ask because i am considering putting a Baleno G16 EFI motor in my jimny but the second hand autos are hens teeth in the NZ Wreckers and they want NZ$1800 for them

[Rotazuk]

Grave digging an old thread

I would expect the vitara ecu has the right outputs to drive the jimny auto ecu . I have a baleno engine driving a vitara auto good as gold so one would assume they are generic outputs , water temp and throttle position .

I would just use a complete 1.6 and its auto , drop off the transfercase and get one of the trail tough output adapters to take the jack shaft as posted on another thread . We used one in the 413 and it has been good . People talked about making the adapter but for $75us you could not make it for that .

Cheers
Chris

PS did you have the diesel vitara , still got it ?

Hi Chris,
Yep still looking for answers on the strength or lack of strength of the Standard Jimny Automatic and if it will handle a Baleno engine swap or if i am going to have to outbid Offroad NZ for an Auto from a wrecker to replace my broken one.
I looked at the circuit diagrams for the Vitara auto and it has a different number of solenoids in the auto and i don't think it would be an easy fix with some diodes to trick the operation of the solenoids from the Jimny ECU.

and yes still have the Peugeot Diesel Grand Vitara but with the increases in road user charges and registrations over the petrol equivalent i have to wonder how economical it really is (but it is still a good tow wagon).

[Rotazuk]

will be finding out just how well it tows this arvo as I will be dragging the 413 all the way to whangarei to Dan's top half fun rally . All up could be a little heavy for it but we will see , so long as the "water wetter" keeps it cool we will be sweet . I have brought a chip to up its grunt a little , be interesting to see what that does .

Anyway back on topic . When I say baleno I ment the j18 engine , same as the j120 in the 2.0 vitara's . Not the g16 engine .

Guessing here but I expect the jimny must run a separate ecu for the auto ? If its similar to the other autos it will want a couple of inputs from the engine ecu . In the case of the g16a auto it needs a water temp and throttle position signal . The J18 ecu has about 4 outputs for its auto and two of these are the water temp and throttle position . By a stroke of luck the output values are the same , ie the water temp is teh same resistance between the two .

So what I am saying is you will still run the jimny auto ecu with a g16 engine . Just need to check and see if it needs two inputs or 4 , if four you would have to run a later model baleno G16b engine as it has more outputs for the later model auto .

If its a club shiney truck then maybe the jimny auto will be fine , only ever heard internet gossip that they are weak . But if it was a shiney then you probably don't need the extra power of a 1600 .

If its starting to become more than a shiney then I would go with the g16 auto because they sound alot cheaper to get , first replacement will save $$$ , you can future proof the jimny - if in the future you need to swap out axles you can bolt the vitara t/case back on and have a centred rear output ( line up with vitara rear axle etc ) and you save the cost of the adaptor kit between the engine and auto , along with any required shimming to get the torque converter in the right place . And heaven forbid the g16 is not enough grunt you can then bolt on a j20 .

The down side is new gearbox mount will need to be made and the tunnel may have to be widened . A 413 does but maybe since the jimny has an auto it wil fit .

I assume your jimny has the g13 engine and not the m13 ?

Cheers
Chris

PS shame you were not looking a few months ago , the engine and auto we put in the 413 was Stu's that he had lined up for his jimny - tinfoil

[Gwagensteve]

The jimny auto was designed for 660cc applications. It's a one off gearbox for suzuki - AFAIK there are no other applications for it. It is designated as a "low torque" auto.

There are no upgrade parts or other variants to pull stronger internals from.

There are no third party sources for parts either - it's suzuki or nothing.

Rodney at Wholeasle automatics has had a look at what's possible and other than a slight increase in line pressure, there's no scope.

Greg's continues to give great service pushing 35's, but that's with a totally standard G13BB in front of it. We know that upping the output of the motor will lead to pain.

They are still miles easier to fit than a AW-4 and miles easier to gear than a trimatic. I have a feeling though that I'll never swap many of them.

Steve.

[sic_zook]

a vitara 3 speed auto is differant to all other trimatics n a m series auto is to hard to mount to a 1.6 but a g series auto will like a five speed n is about the same length but the bottom of the auto dosent fit in a wt tunnel even with a 2 inch body lift n also the jimny autos r shit they burn out like no tomorrow so put a vitara 3 speed auto in u remove th transfer n buy a snout from lowrang that fits staight in the seal hole n a 1.3 jacksharft gos traght in if u want photos ask 11evl his got my old 1 in his car

[droopypete]

it's just too hard

[Gwagensteve]

n also the jimny autos r shit they burn out like no tomorrow so put a vitara 3 speed auto in u remove th transfer n buy a snout from lowrang that fits staight in the seal hole n a 1.3 jacksharft gos traght in if u want photos ask 11evl his got my old 1 in his car

We haven't seen over 105˚C in Gregs, and that's only on long highway climbs. It barely gets warmed up offroad. I don't think it's ever going to get "burnt out" Although it might break if greg tries to put much more power into it.

The key is running a large cooler and ensuring the car is properly geared.

I'm more than aware the trimatic is much, much stronger, and it's the obvious cost effective choice, but it is MUCH harder to gear the car properly on and off road with a trimatic with less than 35" tyres.
