Wow. That's bizarre. My transmission kicks down well before the pedal even gets close to the switch.

Wonder why the switch is needed when the computer can calculate the kick down from parameters like throttle position, speed, rpm, and current gear?

Maybe it is a last resort...if the computer's shift algorithm fails to send a downshift signal to the trans when the pedal is 99% floored, then the switch actuation at the last 1% finally sends the message.

Oh, and I need to get that darn service manual...I bet it isn't cheap!
