Rs4 1996 Auto Transmission

[greedy polish]

Gd guys I'm having a bit of a problem, i just replaced my engine and auto transmission with an engine and auto transmission out of a 1997 stagea RS4. Now the guy at the wreckers said that they will be able to swap straight away but i managed to have a small problem. My 1996 transmission came with 4 electrical plugs but the new box came with 2 so can some one please tell me

1. is it actual possible to run this transmission in my car

2.were can i get some electrical drawings or schematics about how to re terminate the plugs

I managed to buy the whole 1997 RS4 from the wrekers so maybe would it be easier to swap the the electrical harness over or the computer and at controller.

Thanks guys

1996 series 1 , and you have a 1997 series 2 ? , if so you will need to change ecu and loom ! 97 should be NEO engine ! ?

Just to clarify - you have a 1996 Stagea?

Early 1997 were S1 later were S2 with Neo engine and tiptronic gear box.

If you have bought a Neo then you will have to use the motor, gearbox, ecu and engine loom at least. You will also have to use the wiring for the auto and possibly change the steering column over. Also some S2 had lots of airbags so have a good look at the sensor to se if that is all the same as your current car.

RU Polish? Or just a polisher?

I'm going to get the car back on Friday now, am its not a tiptronic from what i remember and I'm pretty sure was a series 1 but will find out on Friday and will post it up. to replace the whole engine loom and the ecu sounds like a bit of work, im an electrician so maybe i will be able to do it my self any idea were i can get a wiring schematic by any chance.

also yes i am polish

ok hear the story now, the 97 model that i have was a series one. The problem is that the transmission in my car came with more cables/plugs that the one out of the 97, The mechanic could only plug in 1 plug into the harness going to the transmission this is the dark/gray plug in picture IMG_0445.JPG . The other plug which is gray/white in color was the only other plug coming from the transmission to the engine bay were they connected. Now on my 96 I have around 5 plugs that use to be connected to the transmission harness wich can be seen in IMG_0446.JPG . The mechanic tryed to bucher the plugs and found most of the same color cables that were needed for the new 7 terminal plug in amongst those 5 plugs. Once he terminated them it realy didnt doo anything, what I was thinking is if i change the automatic transmission controller unit on my car with the one out of the new car and then rewire the harness to the point of termination in the engine bay hope fully it will work. the only problem is that all i can find are manuals for r34 and r33 skylines nothing really for a stegea so i cant find the location of the automatic transmission controller unit and I'm starting to wonder if its incorporated in the ECU ( the location on a skyline is in the right hand kickboard of the drivers side). The mechanic already swapped the ECU with the 97 one. also as far as the a/t gearbox on the plates it says the same thing RE4R01A so i wonder maybe if there is something else missing or maybe did the othere plugs go somewhere else instead of the transmission.

Series 1 ecu incorporates the auto ecu which is why you can't simply swap it out with a PFC or Link.

Series 1 ecus are numbered OV300, OV301, or OV310 of which the first is the most common. They are all similar but have slightly different looms.

What is the part number on the new ecu?

[greedy polish]

k the one out of the 97 thats in now is 0V300

My old one that is out now is 0V310

this starting to sound like im going to have me some fun and maybe will have to swap the harness around

It would seem that your new engine/gearbox is older than your car. If you have the loom and ecu with the replacement engine then that should not be a problem.

Why did you do the swap? Was your engine stuffed? If your original gearbox was working ok put it back in the car and your plugs will connect up problem solved!

If your old gearbox was also stuffed you will have to persevere with the rewiring at the box. I have a Stagea manual (in Japanese) but no pictures of the wiring as yet - I'll have another look.

I ripped my auto box out a few years ago but there is a loom goes inside the box controlling shift solenoids there is one for the reversing switch and one down the back for the speedo sensor,

OK what happened was i needed to get the timing belt done and found out that i couldn't get the harmonic balance off due to the previous owners spinning the key way and put lock-tie on the shaft.. The car has 240000km on the meter but from what you telling me it seams someone already changed out the engine and transmission. By the time i finaly got some cash together the lifter were making shit loads of noise the gearbox was rough as all shit and you could hear the car from 10km away and that's not due to the exhaust. So i went to skyline spares in wetherill park and asked him for a motor and gearbox for my car and he quoted me $2500 out of a 97 stagea rs4 that was siting outside (someone rolled it on the passengers side right off but good for spares). I asked him how much for the whole car and was quoted $3500 so i bought that instead. Bloody happy that i got the whole thing now cos I'm pinching parts from it left right and center. To sum it all up im pretty sure the old gear box is buggered. I'm a sparky by trade and have no problem rewiring the harness or replacing it. With this gearbox the cables that come from it to the engine bay are just in thous 2 plugs. i love to know if thats all the cables that should run to that gear box or do they come out of the harness before the engine bay. If I do replace the whole ecu harness will i need to take the engine and tranny out or will i be able to get around them? Also as a funny point my fule guage was not working so i thought ill get the new one out of the spare car, got it out and realised that the fuel pump in my car is half the bloody size of the one in the new car which is the original one. Swapped them out tonight and god dang did it make shit loads of difference. Happy days i can see this car putting a big smile on my face and most likely loosing my bloody license lol.

Thanks a lot for the help guys, I realy apreciate it. I just cant afford going to mechanics and autoelectricians any more so any info is really appreciated.

Does your engine start and run? If you still have the original engine loom in the car you are probably best to use the original ecu. Changing the engine loom does not require removal of the engine but it is a right pain - you need to remove the aircond fan,abs unit etc.

Is the car driveable? Does the auto work at all?

Wiring the box in place is very difficult. You may be able to get at the wires on top of the box by dropping the rear mounts (may have to undo the radiator hoses I can't remember).

Where do you live? You may need to get some expert advice from an automatic gearbox shop if you can find one who knows enough about Skylines. I have had a look at my Stagea manual - some plug diagrams:

How is your Japanese? Some more diagrams:

The mechanic had to swap cables around on the crank position sensor when they put in the new ecu to make the engine run, the car is drivable but the auto transmition dasent work I change the gears manually by hand, also if I give it a bit much it sort of jerks like a flat spot but a big one. What shits me is the mechanic could have tallied me when he had the engin out and that would of made my life eAsier. See when I get home today I'll try to bell the cables out from the connector in the engin bay that comes from the gearbox And see if it's going to the ecu. I know that the 97 was working ok before so maybe the full swap be the best guarNtee that it might work, if I swap the ecu to the old one im still left with the gearbox wiring that will nead to be changed but if I change the engin harness from the 97 and put it in the 96 I wounght have to touch the wires coming from the transmission. What do u think mate

[chef_stagea]

Just try and start the car. Im pretty sure those ones in the engine bay are something to do with the car knowing ots in park (so you can stsrt it) look in manual

Threads and it will tell u. Im 99% sure with outbthe 2 pin silver one nete ur batt the car will not fire

The swapping of the wires on the CAS is because of the change from Hitachi to Mitsubishi CAS.

I am not sure what you are proposing to do. If you have put the new engine in and you are going to put in the ecu and loom that came with it that won't change the fact that the plugs from the old gearbox don't match your new gearbox? The loom from the gearbox goes to the big plugs in front of the battery.

If you look at the top diagram in my post #12 you will see that it shows where the looms from the gearbox run (more or less).

If you could find someone that could read Japanese that would be a big help!

If you are mechanically inclined I would be tempted to cut my losses at this point and look for a manual R33 GTR gearbox!

[greedy polish]

what im proposing to do is change the big plug wand the loom that goes infront of the battery back to the controllet, that way i dont need to use the old plugs and loom that are on the car now just replace it. what it das look like is thats not the ecu harness from the drawring on post #12 so maybe there is a A/T controller under the seat. If there is i will replace it also and go from there.

mate i would love to put a gtr box in this but i bought this car for the missis and she cant drive manual. atleast it was a good excuse that it was for the missis lol.

[KiwiRS4T]

How many times do I have to say it?

The Auto Trans controller is in the main ecu in the passenger's side kick panel

[greedy polish]

I thought u did say that a couple of time alwready sorry. Sharon proposing is to change the whole loom out of the 97 and into my 96 that way the plugs will be the same just as it was in the 97 when it was running

[dirtyRS4]

the 3 different ecu numbers make matters worse and swapping the loom without engine out will be a PITA.

can be done, just time consuming it maybe the only option left.

[greedy polish]

If I have to get it out I will get a house and a mate to help

I know that I have the wright engine loom for the ecu that's in my car now, it's just that it's in the other car
