    A '91 camaro shouldnt have any electronic components involved with the trans. You will need to get a cable bracket and a kickdown cable though.

    700R4's have a Throttle valve cable not a kickdown cable it controls shift pattern line pressures.
    I'm a black ninja motherfucker!

    they operate completely different.

    on a th350 the kick-down cable does just that, kicks the trans down a gear when hard on the throttle. on a th350 the vacuum modulator control part throttle shift points and line pressure

    on a 700r4 the TV or throttle valve cable adjusts the line pressure inside the trans. it makes the trans shift softer at lower throttle input and makes it shift harder at higher throttle inputs. if memory serves me correctly it also changes the part throttle shift RPM. it also acts like a kickdown cable and makes the trans downshift when going from low to high throttle input.

    Yes your right, although it doesnt change shift rpm thats the governor.. I had to go back and re-remember myself lol. Been a while since I messed with a trans.

    yes and no. i should have been a bit more clear but i figured most people would not understand anyways.

    the modulator in conjunction with the governor controls part throttle shifts.

    True but to actually change the shift points you have to change the weights. But technically yes it does control the shift points
