hI i have a 1994 3kgt and I have the common tranny probs. it goes into 1 reverse adn third. I replaced the filter and fluid, checked the pan for metal and there wa nothing. I have no engine light coming up and i scanned it and it came up with 3rd and fourht gears not synchronized. this sounds like TCU PLEASE HELP!!!!!!!!!!!!

It most likely is the TCU, I have the same problem. On hot days itll make your engine overheat a little bit and you will get sh*tty mileage. It might be your wiring harness to, or the wires to and from the TCU. Get it checked out, its a bit hard to find TCUs online so you might want to get it rebuilt. It will just cost a bit more.

did you change the ECU (engine control unit) or the TCU (transmission control unit)?

as for the Diamante transmission, check the transmission code on that with the code on your 3000GT transmission. here is where you would find the transmission ID. (note: this is a pic of an AWD transmission)
