paddle shifters????

nope. The auto tranny is run on a "tune" based on a couple of factors.
RPM being the main. second being throttle position.
Its just a computer program. You can not add paddle shifters.
Just put it in L when u need to launch or w.e

as far as the paddle shift system goes, it is used on other cars with the 4t45e, however its a computer function. the paddles are hooked to the pcm and the programming in the pcm is what commands the solonoids on or off inside the transmission. when the pcm receives the upshift or downshift command through the data bus signal (its not a simple voltage, the signal actualy goes to the bcm and then through data bus to the pcm) it will ensure its in the correct parameters for the commanded shift, and then it will complete the shift.
as far as adding that system, i dont think the programming for it is in the pcm, and it is going to be a lot of work to try and make it function, if at all possible. the only "easy" option (easy is a relitive term) is to run a stand along transmission controller with a paddle shift kit.

its actualy a lot more complex than that. your transmission shift points and firmness are based on coolant temp, mass air flow, manifold pressure, throttle position, transmission input and output speed sensors, and transmission fluid temp. its not quite as simple as it used to be in the early 90s with the first computer controlled transmissions.
