Hi mate.

Now-to explain a couple of things about the box you have and the shift box from MV.

The shift box converts the Auto to a full manual set-up.

ie-it does not make to box self shift AT ALL. It allows you to run the normally computer controlled toyota box as a full manually shifted unit.

(Once you have it hooked up the trans is fully stand alone unit from the ECU and you can change to a Wolf, Autronic etc engine ECU.)

In the box there are 3 solenoids. Only solenoids 1 and 2 control the gear position, and number 3 solenoid activates the converter lock up.

The wires for the shift and lockup solenoids come out of the box on the RHS.

There should also be a bundle of wires from the neutral start switch, as well as a speed sensor lot coming from the extension housing (only two there)

There should also be a mechanical cable coming out of the box (line pressure cable) that connects to the throttle bracket on the throttle body. This controls line pressure-ie increases it as you put your foot down for harder shifts.

HOWEVER, as you have a JZ box, you will probably have an extra two wires. This is because the JZ trans does not have the line pressure cable like the M series trans. It uses 2 extra solenoids. One for accumulator pressure and one for line pressure.

To control the line pressure electronically you really need to get the ECU to trans connection working (I've no real experience with that bit-sounds like Sideshow knows what he's doing there), otherwise change to mechanical line pressure box (A340 from a 7M vehicle or similar-and maybe that Volvo box-it's the same as an A340) and use the manual shift box.

Don't get too panicked-you'll get it sorted.
