Ok. So I have a 95na auto supra. I bought and had installed a aristo 2jzgte vvti and the auto trans it came with. We are unable to get the trans to shift properly. It will not go into overdrive. Any help would be great. Has anyone ever done this exact swap before? And I'm using the aristo vvti ecu with it.

I haven't come across it yet...and I don't think the Aristo Shift box assembly fits... Assuredly that Aristo ECU needs the shifter position from "shift selector ECU", which located on the bottom of the Aristo shifter box.

Supra... the O/D is just a button on the shifter... the PRND21 shift gate is straight, up and down.

Aristo O/D would be the "D" position on the shift gate... Aristo shifter also shifts left /right to engage manual mode. this is probably the Shifter Position input you're missing..:dunno:. maybe wire the Supra OD button to perform the Aristo L/R switch. A Lexus GS300/400/430 shift assembly will have the same setup.
