Yeah, pretty neat stuff. Here is a link to 6XD: [Only registered and activated users can see links. Click Here To Register...]
CNC machined case, and the dog rings are machined so they are not part of the gear(s), so when you round off the teeth on the dog rings you just replace them and not the gear set. I chose a very close ratio with 1-to-1 5th gear and a .885 sixth gear which gets me to 175 mph @ 7000 rpm. The shifts drop me from 7000 rpm to between 5800 and 5900 rpm, with my peak torque occurring at 5850. My motor is so far back that their best option for shifter placement was still too far back, so they are providing me the C6 linkage that has a shift rod running back to the C6 transaxle mounted gearbox. All I will have to do is shorten the shaft and fab a mount for the shifter where it puts the stick right next to the steering wheel for easy bump shifts. It will take some chassis dyno time to tune the MoTec ECU for proper ignition cut and auto-blip, and you can do that for each gear separately if desired. I'll be damned if I am going to let those pesky DCT-equipped Porsche GT-3s outshift me on the straights like they do to my Viper. LOL Not having to heel-toe in a cramped foot box is a nice side benefit.
