It did take some getting used to when it comes to putting it in reverse and park from drive but its easy for me now. For the 6 speed 4L80 you would need a transmission controller.

As for valve bodies. A TH400 doesn't come with a manual valve body, it comes with an automatic one. I bought my 4L80 with an aftermarket manual shift valve body. Its not bad, but doing it over again i would have liked to have a 4L80E with the full electronics. Having the electronic valve body would make daily driving much more comfortable.

I have a 3.73:1 ford 9" rear end in mine and 315/35R17 tires on the back. Now that i know what kind of torque i have, i easily could have gotten away with a 3.50:1 or similar rear. I do rev pretty high on the highway. My thoughts are the same with the six speed, i would run a 3.50:1 3.42:1 depending on the make of your rear end, becase 6th gear is 0.75 which is the same as 4th gear in a 4L80.

The downfall is the price, the six speeds 4L80 and 6L80 are both close to $7000, where as my 4L80 was closer to $5000.
