I'm using a constant pressure valve body from tci so i don't have to worry as much about the correct setting of the shifting cable. I do have a scheme set out to create some bracketry that will actuate my cable off of my pedal movement which will work in shifting my tranny. But, when i go to set my cruise, my pedal won't be moving anymore, and the tranny won't be able to shift on hills and etc.. I know i can just change to a cable throttle body, but i'm determined to make this hard as possible with the DBW still there. Does anyone know if i can can splice into the output signal off of my TAC to the DBW throttle body and drive another servo out of the extra DBW throttle body i have in my garage? What i have in mind is just using another servo to control all the movement of the tranny cable rather than using the bracketry. Anybody got any insight to this? I'm thinking my voltage will hold up, but i'll lose my current and in turn lost correct actuation of both throttle body servos (ie. half the movement due to double the resistance). What say you?

Constant Pressure valve bodies are a BAD idea, You cant expect a 700R4 front pump to handle max line pressure ALL the time, It flat out does not work! Even if you keep putting pumps in it......The firm shifts all of the time at part throttle WILL break something.
From a safety stand point....Messing with the DBW/TAC is not a good idea either, The good thing it will most likely go into "limp" mode & not actuate the throttle very much.
Why are you "stuck" with a 700R4? 4L60E & 4L65E are great transmissions when built right & are based on the 700R4, So i dont see what your gaining besides a headache.
