Adjusting the kickdown cable

[theholycow]

I found this recently but I don't think I posted it here, and I don't think I've seen it here:

That article describes adjusting the cable that goes from the throttle body to the transmission so that it will more readily downshift when you step on the gas pedal. However, if you adjust it in the other direction, you should be able to use wider throttle openings (for reduced pumping losses) without your transmission downshifting.

Can this help anyone here? I am pretty sure my truck doesn't have that cable and is entirely electronic.
