Matt,
The valve is designed for use on an AOD transmission and is avalible in three different calibrations (I'm using #2). Here is a link to the valvebody page from Lentech's website, click on the AOD Street Terminator. It list for $399 and worth every penny.

To install, you pull the transmission pan, unbolt the existing filter and valve body. Bolt the Lentech valvebody on and drill one small hole in the upper portion of the transmission case, as described in the supplied instructions (can be drilled from the bottom). Run one wire thru the hole and attach it to the solenoid on the valve body.
Put a dab of silicone around the wire going thru hole to prevent contamination from getting in transmission or transmission fluid from splashing out. Attach the wire to a 12 volt power supply with a switch inside the car (mine is on console) and protect the circut with the proper size fuse. Bolt a new filter onto the valvebody and install the pan using a new gasket. Refill with transmission fluid.
You don't need to wire the OD delete function for the valve body to work, but it's very useful at the track or on the dyno. All other functions of the valve body will work with out power to the solenoid. I know that drilling the hole sounds scary, but it's really no big deal.
Since your B&M shift kit is installed into your existing valve body, you can easily sell it for a little more than the price of a new shift kit to someone looking for an easy install. I sold mine with the trans-go kit installed for $125 two years ago.
Unless you switch to a non-locking or higher stall converter your existing cooling should be okay. If you want to make it good enough to run a non locking converter with stock stall, all you need is a 24K GVW B&M stack plate cooler (kit about $50 from Summit) bolted in front of the AC condensor and plumbed in line after the existing transmission cooler. More cooling is always a good idea to extend transmission life.
