tci makes a control that is pretty pricey and trans go makes a manual valve body shift kit.Im using the transgo kit and absouletly love it.You have to manually shift all the gears,but I have no problem with that in my truck.I went though several "built" 700r4s before decided to go with a real transmission.My truck only ran .1 second slower with the 80 vs the 700r4 and I got that back by removing the 3.73 gears installing 4.10 gears.
