Seedy Al Posted September 25, 2012 Share Posted September 25, 2012 hey cats So I am looking a doing a swap my hiace soon, and am Assuming the trans on the new vehicle is going to be an electronicly controlled Auto So Has anyone manualised an Auto before, and if so, what sort of pit falls and things do i need to work out? I assume having a wiring Diagram would be super handy for knowing which solinoids get swtiched to achieve each gear. Any way to figure this out without a wiring diagram?? um, and yeah, what else is invlolved etc? Quote Link to comment Share on other sites More sharing options...
SHGWAG Posted September 25, 2012 Share Posted September 25, 2012 If you've talked to Ewan at Hayatonka or however it's spelt, he & one of his mates manualised his Auto awhile back. Quote Link to comment Share on other sites More sharing options...
vivaspeed Posted September 25, 2012 Share Posted September 25, 2012 I knew a guy that converted a 1UZ auto to manual shifting using a tiptronic shifter for +/- up down. He built a basic circuit using a PIC micro and spent a long time fiddling to make it shift correctly IIRC (not only correct gear, but also timing etc). Microcontroller took the +/- instruction from the shifter and knowing the gear it was in it would output to the correct solenoid to make it go up/down, etc Get Ned to build one? Oh, and I think you have to lock up/switch the torque converter or something? Quote Link to comment Share on other sites More sharing options...
cletus Posted September 25, 2012 Share Posted September 25, 2012 are you going to use the engines original ecu? might be easier to just wire it up so it is still auto. also, if it is an a340, i heard rumors that you could use an early hiace valvebody which is still hydraulic. however i didnt do any research so i might be full of shite. also, there is info about a340s on here i believe.somewhere. www.lextreme.com /probably just enough info to get your hopes up Quote Link to comment Share on other sites More sharing options...
Seedy Al Posted September 25, 2012 Author Share Posted September 25, 2012 Haha I love getting my hopes up! Um not, I am converting the Engine to Manual Deisel Injection instead of EFI, as they are a cunt to wire, hence the doing of converting gearbox to the same I had heard that before some where too there Cletus about the A340's. A this point I have no idea what box i might be dealing with. might get more info and go from there Quote Link to comment Share on other sites More sharing options...
Rookie Posted September 25, 2012 Share Posted September 25, 2012 Al, swing Scott (OKE020) a PM on Performance forums, he used a manualised A340 on his 13's for $1300 Cressida, pretty sure he did it on the cheap too. Quote Link to comment Share on other sites More sharing options...
flyingbrick Posted September 25, 2012 Share Posted September 25, 2012 I have done this to a Nissan auto. very similar. you need to wire the inhibitor switch up to some relays and use the relays to switch the autos solenoids on/off. if you remove the auto ecu you will also need a switch to lock up the tq converter ( very good being able to manual it on in some situations like going up hill in 3rd. mine was set up so that 1st was 1st, 2nd was 2nd, D was 3rd and D + OD switch was 4th, then had an extra push button for lockup. there will be a line pressure solenoid which drops pressure during shifts. on the Nissan I just left thus wire dc'd which ment much firmer quicker shifts with no slippage. as far as I know the mech linkage only controls P,N,R and D21. d21 are all the same mechanically and you can access all forward gears electronically while the stick is in any of those 3 positions. the inhibitor switch is what tells the ecu where the lever is. all you need to find out is what solenoid combinations do what. it will be something like gear 1 solenoid one, gear two solenoid two, gear 3 no solenoids and gear 4 both solenoids. hope this helps.

Spencer Posted September 25, 2012 Share Posted September 25, 2012 The lush way to do this is to use a 5MGE trans ecu so you still have auto shifts. The hard part is you need to track down a old toyota TPS (think early 80's analog 1gge's etc). These output a switched signal which is interpreted by the ECU to determin shift points The waka TPS is a nomal resistive type and the engine ECU takes that and outputs the same signal as above to the trans ECU. Speed sensor for the ECu comes from the box, the solenoid pattern for the A340 is the same as the A43. Its abit of fucking aorund but cheap and worth it if the car is a cruiser, I have all the diagrams somewhere If you want to do it as above, heres the solenoid pattern Quote Link to comment Share on other sites More sharing options...
Ned Posted September 25, 2012 Share Posted September 25, 2012 Chris was asking about such things too. He wanted to put a clutch on the motor still and use auto box to essentially have a sequential setup with just up/down. This is something i could make electronics for if you wanted/needed so flick me a PM if you go that route and require a hand Quote Link to comment Share on other sites More sharing options...

CaMpylobacter Posted September 26, 2012 Share Posted September 26, 2012 lold. isuzu have 'fluid flywheels'(just a torque converter) on their AMT trans (manual gearboxes completely run by computers) in their wee trucks. the larger ones are the same deal but with a proper clutch the small ones are lol as. slowing down and it makes you sound like a douchebag with epic throttle blips and shit. hah. all you're given is a stick like this with them pretty sweet to drive but they take a bit longer to change gear than a standard manual, obviously. auto with a clutch would be wtf spec.

glen Posted September 26, 2012 Share Posted September 26, 2012 Off topic, But a clutch with auto box used to be the go in drag racing. lots of old rails had clutches in front of powerglides etc. Quote Link to comment Share on other sites More sharing options...
Testament Posted September 26, 2012 Share Posted September 26, 2012 FYI the jeep AW4 is essentially an A340 and uses a separate trans computer, which I would guess should marry up to an a340. also I think there are some electronic gizzmo boxes you can buy to replace it Quote Link to comment Share on other sites More sharing options...
Seedy Al Posted September 26, 2012 Author Share Posted September 26, 2012 Spencer. I really like the idea of this Would be a bit of cunt to hack up onto with a deisel, but anthything can be done Quote Link to comment Share on other sites More sharing options...
EURON8 Posted September 26, 2012 Share Posted September 26, 2012 My idea is sound! Haha I have however done no research into the logistics of such an endeavor. so don't ask me for help yet. I will be watching this thread with interest Quote Link to comment Share on other sites More sharing options...
glen Posted September 26, 2012 Share Posted September 26, 2012 ......... solenoids......... .. . Our 1uz powered race truck has a 3L v6 surf trans it has been converted to full manual using the same method, just a mater of finding out what solenoids are doing what.

flyingbrick Posted September 26, 2012 Share Posted September 26, 2012 Spence posted the list above. just need a Pinout for the auto loom and we could draw up a simple circuit in a few seconds Quote Link to comment Share on other sites More sharing options...
