While driving home I noticed that the RR's transmission doesn't want to kickdown into a lower gear. It only does this at speed and in overdrive. It seems to be worse under load on a grade. I have had no prior problems with the transmission. Any suggestions?
Thanks,
Len

It sounds like the kickdown cable. I had the exact same problem.
The part is pretty inexpensive, but the labor can get a bit high because of what is involved in replacing it. I had a local shop do it, cost was around $400.
If you don't want to spend the $, you can always manually shift into the gears.

Good luck,

How do you check/adjust the kickdown cable?

I pulled on the kickdown cable from the top and it has tension because it snaps back. It should be connected at the transmission, right? How do you adjust the cable?
Thanks,

It is NOT a "Kick Down Cable" , its a throttle pressure cable. If its maladjusted it can and will shorten the life of your trans. Just a slight adjustment in tension should be fine to see if it helps your issue , just dont go nuts with it..

Transmission cable...........

Kyle,
Thanks for the reply. Excuse me for the improper terminology. Every automatic transmission equipped vehicle that I have owned has had a "kick down cable". I assumed that it was called the same thing on a Range Rover. Is the cable in question adjusted from the top or the bottom? Do you just remove the slack?
Thanks,
Len

Actually none of them were ever technically "Kick Down" cables. They are all throttle pressue cables that connect to the throttle valve in the trans. YOu adjust it up top and just give it a turn or two on the nut to see if its doing what you need. Just dont go nuts adjusting it.

I am telling you what it is and what its connected to. Its not connected to a kick down valve.... It is there to sense throttle pressure and send that "Signal" to the throttle valve..... Kinda like "Aint" not being a word I guess.....

I suppose I should elaborate on why the terminology is important. If you are just thinking its a "Kickdown cable" then you are also thinking you simply adjust it till you get the desired shifts. Thats not exactly the case though as you are adjusting pressure in the trans when you do this , the valve that the cable controls does indeed raise and lower internal pressure and therefore can cause bad shit to happen if its maladjusted. Ofcourse I doubt you would lunch the trans all together right out of the gate unless you went hog wild with the adjuster but you can bet it will shorten its life by being maladjusted... When I say maladjusted I mean either way. Too loose or too tight.. Either is not good for it..

I had a similiar issue with my 1995 Range Rover SWB. I adjusted the "cable", but there was no change. I even cross checked the "cable" adjustment dimension and performance against a friends Range Rover that was working right.

I checked my ignition system and found that the only problem I had was a bad vacuum advance module. I replaced the vacuum advance module and the issue was resolved.

Hope this helps.

Update...........

Sorry for the late reply. I adjusted the throttle and kickdown cables with little effect on Friday. I then changed the trans fluid and added some Lucas additive. Still no real effect. I then decided to move on to other projects. I had planned to Seafoam the engine. So, I disconnected the vacuum advance line and I then noticed that the vacuum advance unit was loose. I tightened the allen screws securing the vacuum unit and the kickdown problem went away. Who would have thought? I guess the kickdown cable was kicking down properly the whole time. It's kicking down great now. Jim, you nailed the problem!
Thanks for kicking this around,
Len

lol , if you think about it the whole term is pretty much meaningless. What is getting kicked down by the cable ?
