I think some older autos had a switch (not a solenoid) under the pedal, but the SVX doesn't.

The gear is selected on the basis of Throttle and Speed. The best way to adjust it is by reprogramming the chip in the TCU. But nobody knows how to do that yet. Unless you're a computer geek then you're out of luck.

Another option would be to try and fool the system by putting a potentiometer between the TPS and the TCU. So it thinks the thottle is more or less open than it really is. But to be honest you are probably going create a whole load of drivability issues.

Just install a power mode switch and you will be happy enough.
