I would personally be more curious if it affects the lifespan of the motor, as all it really does is allow the motor to rev all the way to red line before shifting. Generally that would be tougher on the motor than the tranny.

Please correct me if im wrong, but thats what I always understood was the purpose of the switch.

I don't know. Definitely gives you worse gas mileage because the trans doesn't up shift as much.

The power button takes my engine to 4k-5k before shifting. I use the power button all of the time because it eliminates the hesitation of downshifting during acceleration.
