Well, I know, I KNOW that 3900 bones is a LOT of money for a tranny, but I wanted to throw this out there. Paddle shift cars, or should I say, paddle shift high performance cars are still fun because they have as many gears, if not more, than manual vehicles. The transmissions that you are talking about are 4 speeds. Why not six? O.K., 3900 bones! Thats hard for me to swallow too.
But I think that if this tranny would bolt up, it would be AWESOME for this type of application. The GM 6T75. Link here -->
http://www.importperformanc...roduct_detail&p=4338 I'm a manual guy myself because it's sorta cheaper, but not really. I'm going to install the F40 6-speed in my Fiero, that means I'll need Archie's kit, so 525 bucks gets the tranny on e-bay, 3300 for Archie's master kit. In total, I'd be spending as much as you once I'm done. You'd get 6 gears forward and it'd be kinda like being behind the wheel of a Ferrari, cough, cough, minus one gear.
Your original question, I'm a manual guy so I don't really know. I'm guessing you'll need a shift kit. I'd think the best bet is to contact the guys over at FastFieros, I know they sell the Twist Machine paddle shifter for $650 and probably anything else you'll need, like something for your computer. Sounds like the difference between the 4T40 and the 4T45 is the hp/tq rating. But with the 6T75 rated at 315hp/300tq, which we all know is a low ball figure, probably will work with anything you throw at it.
One more thing, kinda out there to MstangsBware, that was a G6 with paddle shifting you drove? If it was anything like that new Camaro I drove, that was not real paddle shifting. That was, you can kinda control your shift in a cheap GM kinda way. A real paddle shift car, like a Ferrari or Lambo, the shifts are crisp, clean, and with virtually no lag time. You'd never get a shift denied message, if you wanted to, you could start in 6th gear, the car would do that, probably stall if you didn't have the power. In built for paddle shifting transmission you can even skip shift. To do the conversion right, you have to look at every aspect of it. Will the transmission shift without me telling it to, in other words, will it continue to act like an automatic transmission. If it does, then that needs to be fixed, it's only fun if you are in control. With that Camaro I drove, those paddles were just for looks, and yeah, no wonder you don't use them on your G6.
