I noticed my trans has a kickdown cable, but it is already as far up as it can on on the adjuster. I am putting a manual in it soon but for now I wish it would downshift a little easier.
It is not really a kickdown cable like on the old c-4s and such. Where on the old c-4s shifts are controlled by a vacuum line from the manifold to the trans the AODs are controlled by the TV cable(the kickdown cable you see). The transmission shifts off of throttle position vs vacuum. If you screw up the TV adjustment it can do some serious damage to an AOD.
If you go over to Click Click Racing and look in the auto trans forums there is a sticky that has several articles on how to adjust the TV cable.
