Anybody have one laying around by chance? I finally got my SOHC 91 Galant 4g63 motor rebuilt and running, but the auto trans is in limp mode...took apart the TCU and had the good ol leaky capacitors, and it looks like the processor has overheated..I can get a rebuilt unit for around 220 bucks, but I figured I would try here first..Also took apart the main engine ECU, and found 2 leaky caps there, but it still worked, the only thing that was happening was the tell tale "clicking" of the underdash MPI relay..I'll prob be stuck buying the new TCU, but I can save the ECU with some new caps..haha I've been putting in too much damn money in this car for a winter beater..damn Mitsubishi :)

Your best bet would be Ebay. The SOHC 4G63 isn't a DSM engine and not really popular among Mitsu enthusiasts. :)
