Turbo 350 Transmission Kickdown Adjustment

[81GMCSierra1500]

Hi geezer,

Here are a couple photos of my throttle cable/kickdown bracket, in the photo where the kickdown cable is visible, the cable itself appears to be very slack, as it bends in between the housing and valve assy. The upper one and spring are not the worry (they're the throttle cable & return spring), but the problem is, I couldn't really get my fingers in the space where the button could be, and when I did, I couldn't feel any sort of "adjustment button." I've attached a photo of the trans too, so you guys can judge what kind of trans it is, I know the photo isn't great, I never got a "full view," but my original had a cruise control option, and the replacement was identical, minus the CC. (I was told it was a Turbo 350.

This just in... Did some research, I have a 700R4 Transmission, not a 350. If that is judge-able just be looking at the kickdown cable. At least that's sorted! Now, same adjustment procedure?
