I bought a 1991 4dr non turbo rwd with a bad tranny. I have installed a replacement transmission but am now having trouble getting overdrive 4th to work and it also feels like it is starting off in second (really slow!). I have tested sensors and solenoids and all test good. The tcm is my question. I can’t get the power light in the dash to come on to test it. Won’t come in when you turn the key or when pressing the button. I can’t find and pinout or wiring schematic anywhere for it. It is a 48 pin plug. Ecu has no codes.either. I did get the power button light to come on with the last transmission but it was intermittent.

The R32 GTR manual has everything you need. Yes, including the TCU wiring for non-GTR autos. Because it also covers GTS4s, including autos. The AWD and RWD turbo and NA autos are all similar enough wrt the power button and TCU interface.

You should consider getting it to a mechanic who has a good diagnostic scanner and find out what codes the TCU might be suffering with.

      It is an absolute lottery. They can and have died at stock boost with low usage at all. The turbos are now anywhere up to 36 years old!

      Huh, wonder why it blew then. I never really beat on the car THAT hard lol I dailyed it and the turbo blew after 6 months

      That's odd, it works fine here. Try loading it on a different device or browser? It's Jack Phillips JDM, a Skyline wrecker in Victoria. Not the cheapest, but I have found them helpful to find obscure parts in AU. https://jpjdm.com/shop/index.php

      R34 GTT RB rough idle problem with weird RPM gauge fluctuations

      By GTSBoy · Posted

      Yeah. I second all of the above. The only way to see that sort of voltage is if something is generating it as a side effect of being f**ked up. The other thing you could do would be to put a load onto that 30V terminal, something like a brakelamp globe. See if it pulls the voltage away comepletely or if some or all of it stays there while loaded. Will give you something of an idea about how much danger it could cause.

      I would say, you've got one hell of an underlying issue there. You're saying, coils were fully unplugged, and the fuse to that circuit was unplugged, and you measured 30v? Either something is giving you some WILD EMI, and that's an induced voltage, OR something is managing to backfeed, AND that something has problems. It could be something like the ECU if it takes power from there, and also gets power from another source IF there's an internal issue in the ECU. The way to check would be pull that fuse, unplug the coils, and then probe the ECU pins. However it could be something else doing it. Additionally, if it is something wired in, and that something is pulsing, IE a PWM circuit and it's an inductive load and doesnt have proper flyback protection, that would also do it. A possibility would be if you have something like a PWM fuel pump, it might be giving flyback voltages (dangerous to stuff!). I'd put the circuit back into its "broken" state, confirm the weird voltage is back, and then one by one unplug devices until that voltage disappears. That's a quick way to find an associated device. Otherwise I'd need to look at the wiring diagrams, and then understand any electrical mods done.   But you really should not be seeing the above issue, and really, it's indicating something is failing, and possibly why the fuse blew to begin with.
