Mine uses the TPS for kick-downs as well, but there's also an "on-off" switch mounted on the throttle cable where it comes through the firewall. It is switched on when the pedal is completely floored. It requires the tranny to make a mandatory downshift to the lowest possible gear it can make without overreving the engine. For instance at speeds less than ~75mph it will do an instantaneous 4 to 2 downshift (skipping third). It also shuts down the A/C compressor (I think, unless this feature is controlled by the TPS). It's a kind of "holy $%*&, lets go!" switch. There is a distinct "click" when you floor it enough and it meets with some resistance. I think it's Volvo's way of making you think before you invoke it. There's kind of two positions on my pedal...floored and floooooored.
