Agree with you re: the Fairlane. I guess it's how we each describe it!! Mine sure didn't stick to the speed limit down some steep hills, it would overrun and I'd need to check the brakes to keep it at the speed.N.T. wrote: Jer2000 your Dmax should not be running away down hill, if it is there is a fault. And I can also guarantee my 91 fairlane also did not run away down hill. With in exceptions of say 5-8 ks is O.K. but a complete free roll definitely not.
Some of my cars were better than others though. My wifes Captiva if in full auto mode, it tries to shuffle down the gears to keep the speed at check, but not always effective. When in tiptronic type mode (whatever the name for that is) it sticks to that gear and can run away faster.
As to my D-Max, as I said before, mine is a manual gearbox. My downhill speed control on cruise is limited to whatever engine braking the gear it's in can provide, and as such, can run away depending how steep the hill is! 4th gear may hold speed, whilst 5th gear may allow it to go over the speed limit unless I manually brake. I drive down a combination of the Snowy Mountains Highway and Monaro Highway each week, I now know which hills it will slowly slip away on, versus those it holds up well - and actually applies throttle on as it's a slight gradient!
