Tranny Kick-down Question

[Zilverado]

Hi Guys,

Well, now that I have the engine running better (clean fuel filter), I do have another question - this one about the tranny kick-down. The tranny is a 700R4.

When driving down the highway (or up hills under load), the tranny does not respond very quickly to a pedal to the floor. It feels like it should kick down, but it seems to take a while or not at all, until the engine really starts to lug.

How is this kick-down controlled? I can recall reading stuff on this (and will do a search when I get a second), but can someone shed some quick light on this, or at least pont my nose in the right direction?

Thanks.

There should be a vacuum switch on the firewall that is part of the control for disengaging the lock up torque converter. They can be wired several different ways inside the transmission. They can be setup where the lock up only happens in 4th gear or 3rd and 4th. More than likely yours is setup where it is only in 4th. A pressure switch is used in the transmission
The tv cable (kickdown or throttle valve) may only need adjusted. Unlatch the lock where the cable connects to the bracket beside the carb. Make the cable longer by 1 notch and see how that feels. If still not right move it one more notch.
