Hi all,

I have come across some information that will be an absolute Godsend for those out there with an AUTO r33, I have done this mod myself and can tell you it will definitely quicken up your shifts for $0.

O.K here goes, on the inside front, drivers side, of the engine bay, facing the engine fan are 4 plugs on a bracket.

The TAN coloured plug is the one you want.

Find the red wire on this plug and cut it.

You can put a switch on it if you want,I did, which will allow you to switch your shifts from hard to soft.

Although I am told, its not as fast shifting as the valve body upgrade, the difference is very noticeable, Going around a corner at under half throttle my r33 chirps when it hits second.

Give it a go, it works wonders.

Disclaimer:-Do at your own risk as I am not a mechanic, and don't have any degree I am simply passing on this awesome info (I got from a mechanic) to fellow skyliners, and am void of any responsibility if anything were to go wrong with your car. (It sux how much you got to cover yourself these days)

any got an engine bay pic and can put a circle around the plug so i know which one it is ...im intrested to know what it does...

and with harder shifts do you think it will cause any damage to the auto, as the shifts are a lot more harsh ??

The wire you are talking about is listed on the wiring diagram as one of the feedback for the Auto to tell the Ecu when it is shifting this would cause a similar problem to using aftermarket Ecu's. No feedback = harsh and erratic shifts as the ecu will not retard the power with out the Auto telling it to do it.

I will definately not be doing this crazy D.I.Y. you can make your own decisions.

    • LOL, when one "money pit" is never enough Noice, and excellent work mate
    • I have more than enough digging, laying blocks, moving gravel, airrating, feeding and top soiling the grass, and setting up the veggie gardens growing some seedlings,  and then removing all the unused rock to keep me busy for the next few months at least,  hopefully the rain stops soon so I can get a few hours in this arvo, but, before that Sunday is washing day, is every body happy, you bet your life we are Nice country road day drives are a day off whenever I'm muscle sore from all the landscaping at the moment, but, more epic multiple day drives will start once the majority of the big jobs outside are completed
    • I hear that would involve some nice country road drives into the hills for Mark...
    • I thought I'd come back and add something I JUST learned. A Toyota LandCruiser with a 1HZ, mates perfectly with a bottle of Nulon brake fluid. As in, it perfectly screws in. Great make shift funnel when you cut the bottom of it off. This may work for your Corolla.   Unfortunately, tipping a 10L drum is much harder than a 4 to 6L bottle, and they no longer include the easy pour tap which was just perfection to use previously.  
    • Guys since i bought r33 gts25t coupe 1994 automatic a/t(manual swap 350z gearbox)  all i got is problems, always problems. Lets start with that when i turn key into ignition(ON) fuel pump doesnt always works. Sometimes i have to turn key twice Off/on/off/on until it primes. Its new, dw300 - 340lph. My gearbox broke so i did gearbox swap, install different intake manifold, injectors and i take pipes. Car was sitting in garage for more than half a year. I did assembly all not that long ago and when i turn ignition cant hear prime. All of sudden it stopped working. Theres many videos on YouTube how to make relay mod on r33 straight from battery so i did and it doesnt work! 😰 30 - battery positive  87 - positive from fuel pump to relay 85, 86 - one of two wires from original fuel pump wires(light blue, grey) and it didn’t work. so I check on ignition and took original BLUE relays wires from trunk, next to fuses. (I believe it’s IGN+ and ECU pin 18. it didn’t work…  tried connecting (IGN+ from og relay) and (ECU 104 from 1of4 FPCM wires) to my new relay 85/86 and it didn’t work.  I unplug FPCM. Didn’t work. im thinking what’s wrong   fuel pump is working, if I leave IGN+ on 85 and 86 straight to ground it works but it’s just nonstop. Since it getting constant 12v after key in ON. light blue wire gives me 6-8v.  so how this should be connected? What causing ECU not giving — on pin? Or I did sth wrong and that’s why it doesn’t work? I need negative signal on ECU that control fuel pump. What this should be?
