You have to picture yourself going back and forth from paddle shifter to floor shifter. And even if your car is slow, you will probably hve some gears left over at the end of the quarter. And we haven't even begun to discuss the limitations of downshifting with a TH400/GV while trying to negotiate a corner.
I believe Jim (who just bought Shay's car) will be selling his TH400/GV to install a 4L80 so that he can take advantage of full electronic shifting (up and downshifting) The GV unit is not the problem. The problem is the slow hydro-mechanical slushbox TH400. A TH400 uses fluid flow logic designed 50-plus years ago (valve body). A 4L80 uses digital logic. That's the difference.

If you guys want to try it, I'll be happy to help in any way possible. Other than being able to claim six gears, I see no reason for a TH400/GV in a Pro-Touring car.

Remember that you could hook a gearvendors unit to a 4l60e transmission.. 8 speeds would give you a better range of gears..
