I have a 1984 Corvette with Crossfire Injection and a 700R4 auto trans. Does anyone know how this TCC is controlled? I think its electronic but not sure if it goes through the ECU or not. I am afraid it will not lockup anymore at higheway speeds after i scrap the EFI. I am leaving the ECU in place to control my Digi-dash so thats no problem. Can someone clarify this for me? Thanks.
