Hey Peoples,
Recently (like the last 4 trips I have had) while driving up the Kuranda range when nearing the top I my speedo has began to go nuts. The car gets quite warm running up the hill as it is under constant load for maybe 10 minutes. Temp gauge rises above half way to mid A (in NORMAL). Voltmeter displays 14.5 as it should and taco works normally too.
In the worste case my speedo was swinging like crazy and displaying a speed of around 20km less than i was doing. Once clearing the top of the hill (just after symptoms begin) the car runs quite cool drifting down the other side yet the needle does not compose itself. After finishing the range I usually have to stop at one set of lights before coming home. At this point gear box seems to be getting quite dazzled (with it falling into limp home mode on one occasion).
Any ideas what the problem could be?
