I found instructions from turbo action it dose not look hard. And I recently replaced the transmission in my car it has an internal vibration so it came out to get fixed. it has the reverse valve body in it I do not know what brand it was in the car when I bought it and built by a guy in Oregon I can't find info on. I got a used tci transmission to put in while I fix the other transmission but the tci one i need a kickdown setup. I would like to put that reverse valve body in the tci 727 rather then spend the 100 plus on all the kickdown stuff.
