That I'm not sure of. Isn't that the trans that comes with the N* engine?

Another option might be the F40 from a G6. I belive its a 6 speed manual

I looked on G6 forums about the F40 before and it seems they have just as much likeliness to bomb as the 4t65e

The F40 is only good for a light car. Generally, the "rule" for a manual transmission is you don't use it on a heavy car. Semis, trucks, vans etc are different. I guess you could build up a manual to haul a Bonneville with V8 power, but the gears would be loud and the clutch alone would cost over $1000.

The 4T65E-HD was used on another forum'* 536 WHP Grand Prix for two years before finally it broke the hardened input shaft on a track run attempt. They have since rebuilt it and are planning for 900 WHP with Porsche axles, some crazy input shaft, etc. You can do anything if you put your mind up to it. If you want, you can build a 4T65E like the GP guy did and drive it for two years until you tear the input shaft in half. Or start with an even stronger one since I believe today'* input shaft metallurgy has changed for the better.

Anything is possible, as you can see in that it is possible to have a whole thread about people warning you about having more than 300 horsepower at the crank. I might be biased because I badly want to see this done, so please weigh your options and make a sound decision (and then post pictures of the swap!)

Pontiac Jeff has a 4t80 mated up to his twin charged L67. The cadi trans is an option.

The more I think about this idea the more I want to do it.. Now how about getting the paddle shifters from the gxp or comp g gps? The six speed is tempting but I want to drive the car everyday and my left ankle is basically ruined for driving a manual everyday..and believe me, I would love to do that.... the the tap shift on the gps is kinda intriguing.
