Manual To Auto

[Room42]

Ok I did a search and found 167 results for 'manual to auto conversion'. The only thing is that I am looking for manual to auto and every thread I saw was about auto to manual. Anyway I have an rb30 auto in the shed and I want to make my r33 gtst an auto. Why you ask? Many reasons, one of them being ease of driving. Btw when I replaced my radiator the other week I replaced it with an auto one so I already have the heat exchanger in the radiator. I have the rb30 flex plate and torque convertor as well. I have replaced many a gearbox and will have no trouble swapping it over, providing that I wont get halfway and then go "f**k I have to pull it out again". So if you know a thread that has this covered then put up the link or lemme know if this is a viable option. Also it will be molesterated by a gt3582r so I want it to last longer than a day. Thanks in advance.

To start with, your RB30 box is not going to last with the full potential of that turbo. You could possibly have it built to handle it but I have my doubts.

If you read the auto - manual conversions....just reverse it. You would need an ECU with that turbo mod so assuming you go with a decent ECU like a V500 or a Platinum, it should be capable of auto control. The rest is just bolt in stuff in reverse of the opposite conversion (clutch pedal box removal, brake pedal change, flex plate, auto + converter, tailshaft, shifter etc) The rest is done by the ECU

Ha yeah the mrs will drive it occasionally and auto's are quicker. I pretty much knew what I had to do in terms of the swap but wasn't sure about the comp for the auto. I'm running a pfc so that means no auto control. It would not bother me in the slightest tho if I had to shift the auto box from 1st up to drive like a manual. From the sound of it so far I will be waiting till I upgrade my ecu. Or till the clutch breaks or something like that. Thanks for the reply Elite Racing.

I was just about to create a thread similar to this. The reason I want to do it is for drag racing.

What exactly do you need "auto control" for? The transmission simply cannot run as a standalone unit similar to old USDM autos? Like it wouldn't shift at all or what? If I do need "auto control" I guess my goose is cooked because I'm running an RB20 manual ECU with nistune.

You need auto control to control stuff like fluid pressure and when the trans shifts. Considering there aren't many wires coming from the gear box I daresay it would be fairly simple to get it to shift the way you want with a couple of resistor pots and switches or the like. I cant see it being too hard to get a signal from the ecu that would do the trick when used/modified correctly. But I've never done it so I could be digging for gold in a drop dunny.

Rather than buggering up a perfectly good manual Skyline, just go and buy an auto one ferchrissakes.

Who said anything about buggering anything up? And if I had a spare $15k to throw at a skyline it would be the one I have not another one. But you can buy me one if you're that rich.

[GTSBoy]

Auto into Skyline = buggerring up. Sale of existing manual Skyline followed by purchase of auto Skyline = same financial position without the f**king up of a manual car.

I think it's a good idea. What about the simpler boxes like the Ford C4?

There is only one problem that can be encountered from that setup.....he will have ford parts on his car. May as well drive the thing off the edge of a quarry right now.

R32/33 auto boxes have a separate control unit that would really just need to be fed the appropriate inputs from the ECU.

R34's TCM is part of the ECU.

Something I would like to figure out is how to control 34GTT tiptronic box without having to wire in a whole 34GTT ECU..

A simple solution would be a fully manualised Jatco box (someone has one for sale in the WA area at the moment).

Can a guy manualize an R33 auto gearbox and use it without the control unit?

^ That is what I was thinking. Except they want $3200 and I could build my own for a fraction of that.

As far as selling the car I have and getting an auto one I would be no better off. I have put stacks of money into this one and I would be hard pressed to get it back if I sold it. Would you pay $14k for a stock looking 95 s2 r33gtst that has shitloads of bolt ons? Thats what it cost me. Even If I put all the stock parts back into it and sold it I would be stuffing around for a few days to make it stock again not to mention fitting it all the bits to the new car. Then I would have a slow as f**k auto skyline that cant run the injectors or the afm or the turbo that I am putting on in a week or so. And if I were to keep the pfc and use it then I would lose the auto control anyway. Or I'd have to upgrade my ecu which would cost another grand on top of the pfc sale price. Then I'd have to mess around for a month driving here and there tuning it. Since I already have an auto trans that came attached to the rb30 I bought I will use that. Who cares about changing gears when you have more power than you can use? For me an auto is better at high power for street use. Just floor it and hold on with both hands.

Not sure, I think MV Autos do some sort of shift control box for them though.

I've got a 34GTT auto sitting in my carport and after experiencing the tiptronic in the Stagea I'm trying to find a way to put the tiptronic box in the 32. Need to get my electronics mate to have a look in the 34 ECU and see if we can maybe extract the TCM chip (it's a separate board) and feed it some inputs..

[ST240]

I cant believe the lack of info on this subject; compared with the loads of other great info you auzzies have . I've been scouring the internet for the last 3 hours and I haven't come up with much. It's almost worth me going custom and adapting a bullet proof Chevy auto. This way I know it will work how I want it to. I've emailed MV Automatics. I hope to get a response out of them.

[GTSBoy]

It's a separate board but it has a huge number of pins. It's not truly separate - it relies on a lot of the engine ECU's stuff to do it's job.

If you want tiptronic in the R32, your best bet is to get a whole Auto Neo engine and trans and put it in. It will make it better in every single way....except that it will be an auto instead of a manual, which will ruin it as far as I'm concerned.

I took great pleasure in removing the TCU board from my Neo's ECU and throwing it in the bin when we opened it up to put the Nistune board in it.

Check this out. You can buy a conversion kit including bellhousing to fit different transmissions to the rb30.

I know someone who has a manualised trimatic for sale that has handled over 350 rwhp. Sounds good to me.

I went through all this not long ago, rebuild a Jatco that will only last so long. Find a ecu that will control it and so on. I ended up putting in a powerglide so i could choose

whatever ecu i wanted. Bought the parts to rebuild it from Summit racing and you will have a box that will last.
