Shifting Question: no downshift/kickdown

Situation: 1999 RR 4.0 Gems with 190k miles.
I recently did new head gaskets (myself!) and all went well. But, since then, the transmission does not want to shift down to a lower gear when I want to accelerate. Obviously something I did, or forgot to do. But what?

Can anyone tell me: is this function mechanical, electronic, vacuum-assisted, or what? Once I know this, I should be able to trace back to the problem. Thanks for the help in advance,

WHy no answers? SImple question...

Should be an easy one. Is everyone away on summer holiday or what?
Still need more info - trans downshift problem

Thanks for taking a shot, but I'm sure someone out there knows how the Kickdown function works and can just tell me to save time. Thanks, KO.
MIsunderstood ...

I apologize for not being clearer. I know someone here can tell me what it is on a '99 P38 that makes the transmission shift down when I depress the pedal to accelerate. There are 2 cables going to the intake, I've tried randomly loosening / tightening each and both, no result. There is a vacuum tube from the intake right next to where the throttle cable reaches the intake, and it goes to a round black cylinder thingy - can't see how this relates to shifting. Wires - can't see any electrical anything near the throttle or intake. So? If someone can just tell me what controls downshifting, I can solve it. Is this super-secret restricted information? CIA? NSA? Whistleblower fears? Range Rover owners are a strange crowd.
Other news: I put in the front of the axle tie rod last week, just picked up the behind-the-axle tie rod today (called track rod), putting it in tomorrow. With the new (used) tires, I should be in great shape!
Also: this summer I took out the headliner which was sagging and put in a new one. Hardest part - finding fabric the is more than the standard 54 inches. RR's require 56 inches minimum. 10 trips to Jo-Ann fabrics, but finally found it!
Also: Hurricane wheels are beautiful but damnably difficult to clean.
Thanks for listening. :wave:

Thanks RoverGuy, now I know where to look.

Much appreciated. I'll check and see what I can find.
