I had a B&M electronic shift enhancer on my 94 F150 w/E40d. I'm just wondering if anyone makes one for the newer automatics, (like in my 97)?

 

B&M makes one for the '97 4R70W. I don't personally feel comfortable with an electronic shift kit though. A mechanical shift kit is safer than simply increasing presure electronically.

This is very informative info.

Valve bodies are available through LENTECH and Performance Automatic. There are also mechanical shift kits form TransGo, Level Ten, Superior Transmission, Fairbanks, Baumann Engineering.....

If you have the 4R100, then there is the Factory Tech valve body.
