Yes they do. Most companies you want to shy away from because there have been problems with the shift kits in the 4R70W. The best companies to go with are Baumann, Art Carr, and Trans-Go. There may be others that are good, but those seem to be the most reputible. Rather than a shift kit, it would probably be best to get a whole new valvebody. You can get those from Fordchip, Art Carr, and Baumann.

The other way to go, is to do the Jerry Mod. Jerry is one of the designers of the 4R70W for Ford. He gives detailed instructions on TCCOA.com how by simply removing the stock valvebody, and drilling a few holes and removing a spring (I think) will do the same as a shift kit, if not better. I would recommend that, and will be doing it myself shortly. Check it out in the tech articles under transmission on tccoa.com. If you have questions you can ask A-train on TCCOA.
