Thanks Jason did you try to used the column shifter or did you go with the rachet, I was able to fab up some brackerery for the stock cable but I think the spread between the gears might be alittle diff, I got the tranny in but the converter is way to high for my dailt driver, as for the speed sensor where is the write up on the conversion I would like to find out about the wires I had to take the control off the side of the 4l60e and plug the wires but in so I could drive it home.

03 2500hd 4×4
Help!!!!!!! 2003 Silverado 2500hd 4×4 6.0L with 4l80e transmission just had our 3rd tranny go out so I wanted to know if the turbo 400 will bolt up to the transfer case or what parts are needed to do so...

This should answer a question of yours.
You can think of this trans as basically a TH400 with a 25 percent overdrive tacked on. The 4L80E transmission was mostly used in 3⁄4- and 1-ton trucks and larger SUV applications beginning in 1991. The “E” means that it must use an electronic ECU for control, as it will not function without it. The trans has experienced multiple minor upgrades over the years, with the newer boxes being a bit more attractive, but all the versions can be made to work well in a performance application. The addition of electronic control and overdrive adds roughly 50 pounds and a slight amount of width over a TH400, but for the most part, any floorpan that can accommodate a TH400 can also fit a 4L80E. Also, the 4L80E transmission is typically about 4 inches longer than a TH400 (depending on the length of the extension housing), but the trans mount is located roughly 11⁄2 inches rearward.

I'm doing the TH400 swap now. The neutral safety switch and reverse lights can be wired through the shifter. I'm using a b&m pro ratchet.
I had a vss sensor put in the tail housing. I have to swap the plug but it should work fine.
For the cross member I would recommend looking here:
