R32 Gtr Gearbox Problems.

Alright, so i dumped the oil from my gearbox the other day and filled her back up with the correct amount of oil through "THE GEARBOX LEAVER" thinking that this gearbox would work the same way as any other gearbox i have serviced. Anyway so i out it back together and start driving home, by the time i got there there was oil all the way down underneath my car and on my exhaust. Found the problem being the gearbox leaver boot, so i replaced that and topped it back up with oil, this time through the top lug on the side of the gearbox, this was more of a quick job so i found the best oil i could for a midnight on Tuesday and put her in(happened to be multitrax).

I wasnt to happy with this oil so i bought some new stuff today and replaced it again through the leaver, problem is when i go to check the level from under the car i cant get it, and the oil seems to be sitting in a gallery on the top part of the gearbox, or the transfer case.

For though who know rb26dett gearbox's you will realise they have a chain system and a oil pump inside of them, my question and i couldn't find the answer through all the reading i have done, is the main gearbox and the transfer case connected and run the same oil? or are they different galleries? I really need some help on this! my car is sitting up on jacks.. sad.gif

cheers jake.

No (in terms of oil usage) and no.

The transfer case uses ATF and the gearbox uses.....gearbox oil. The shift lever bolts to and connects inside the transfer case in the GTR gearbox. So when you filled the 'gearbox' through the shift lever hole, you actually only filled the transfer case....and it would have been waaaaaaay overfilled, thus the cause of the leaks, not to mention using the wrong oil.

In fact, the filler plug for the gearbox is on it's side, accessed from the underneath the car. For the transfer case, the filler plug is at the back of the case and also accessed from below.

Suggest you get hold of a workshop manual.

      The wiring diagram for the R33 RB25 is freely available, and is essentially the same same as most other RBs (just with differences as to which pin # does which job). To get the ECU to power up, you just need to provide power to the ECCS relay, and have the other power feeds that come in from the top left of the wiring diagram (wrt the ECU) that give perma power to the fuel pump relay, the ECU itself, etc etc, all connected. When you put power on all these it will just come to life. It's pretty clear from the diagram what needs to happen. Just follow the lines from the 12V + supply stuff in the top left over towards the ECU. I've even posted snips of such diagrams (not for vanilla 25, I think for Neo and 26) to various threads here in the last few months, talking about what it takes to get the fuel pump and FPCM up and going. Search these up and they will help get you started on doing the same with the vanilla 25 diagram. Hell, for all I know, I've done the same with that one in years past and have forgotten.

      Yep...so unless someone posts up the answer you will need to probe from the ECU connector to the dash plug with a multi meter in continuity mode to trace the wires.  Note the ECU has multiple - and + (and across different key settings - Battery, IGN and Start) and most likely the power is fed from the connector(s) that is normally near the left hand headlight.

      Thanks Duncan, I am actually just trying to get the Rb turning and running with the RB25DET S2 original loom itself  I am just trying to get it going outside the body and not thinking about the S15 or trying to match anything to the S15 loom at all I am only trying to see if anyone has done this and what pin they found to be the ignition trigger and ECU+/- on the dash connector, that's about it. Thanks

      Hi Guys, Does anyone know any aftermarket part numbers for a starter motor to suit the VQ25DET? I can find lots of alternative part number for the VQ35DE, which I assume would fit, but there is a lot of conflicting information out there. Thanks..

      I don't understand how this hasn't boiled down to - Upgrade the turbo when you have everything required. ECU, injectors, fuel pump, turbo, etc. Do it all at once.  If you don't have everything required, just enjoy the car as it is and keep saving up your pennies.
