What all does it take to replace my c4 with a 4R70W, besides $$$. How do you control the solenoids? I’m sure you will have to shift it manually all the time w/out the computer? What about OD, can you install a manual switch? Is there an adaptor to go from the 4R70w to the Dana 20. Last question, I’m assuming the 4R70W is longer and the front and rear drive shafts needs fabrication?.
