Hello Everyone, forgive if this has been covered elsewhere; I did not see anything in a search.
I have been having a strange problem with the functionality of the cruise control and the subsequent shifting of the transmission. My dealer service dep't. claims it is normal and Land Rover corporate does, too. Here is an excerpt of the letter I sent to corporate.
... Secondly, (but of most importance), the transmission operation while using cruise control is SIMPLY NOT RIGHT!! As briefly as possible -- During normal driving (without using cruise) the transmission shifts through all six gears while attaining highway speed. When a grade is encountered, the transmission might downshift from sixth to fifth or even fourth, but then goes back to sixth soon after the terrain levels out. When using cruise control; however, it's a different story! The transmission will downshift normally when going up a grade or when passing, etc., but WILL NOT then upshift to sixth gear like it should. It will resolutely stay in fifth gear unless/until the vehicle goes DOWN a grade or we "tap down" the cruise control a couple of miles-per-hour. Only then will the transmission shift into sixth gear ...
Does anyone else have this problem? My LR3 (2006 HSE V8) does this all the time. Several times while trying to sort this out I have waited as long as 2 miles after the downshift while traveling on level ground, but the LR3 won't upshift to 6th unless I "tap-down" or go down an incline. Doesn't matter if I am in Sport mode or Normal. Doesn't matter if the LR3 is cold or has been driven for many miles and warmed up. The transmission functions fine in this regard when NOT using cruise (either in sport or normal modes.)
Also, I have the "transmission jerks when almost coming to a stop and then going" condition reported here elsewhere, but that is a separate issue I guess.
Thanks for any responses - they are much appreciated as I continue to argue with the dealer and Land Rover North America.
