Thread: Cooper LTZ Zion issues?

Hmm re the no low range.
I read a reprot by a bloke with a new Freelander who went up Mt Pinnibar . AFAIR it was on Exploroz.
Anyway he got to the top OK but he reported in passing sort of that his transmission overheat light had come on on the way up.

Now IMHO one of the functions of low range is to keep the transmission cooler than it would be in high range in slow going as there is less torque converter slip particlularly in sand on on very steep long hills.

Granted the new transmissions have a lower first but I doubt that it is as low as low first or second in a car with transfer box.

As many of us know, a transmission overheat light is not good and I wonder how many transmissions will be trashed by people without low range trying a bit too hard.

What pressure you use is so much a drivers decision which can change day to day depending on road conditions. Yes it also alters with different sidewall aspect ratio's.

Experience plays a big part of this decision.

Exactly. And therein lies the problem.

I think too much misinformation is spread regarding lowering tyre pressures - 4wd magazines and the like saying you must run at this pressure etc, which people treat as gospel. Look at the Coopers recommendation earlier. Just saying run the same pressure all round suggests they don't understand what's happening on the Disco. LR recommend higher pressures at the rear for a reason.

The simple fact is that different tyres, running under different loads, in different conditions need different pressures to work properly. With high profile tyres running at low speed you can get away with a lot more, but as the profiles lowers the pressure becomes more critical as your playing with less sidewall.

I did a trip with a FL 2 in Toolangi.

The first big hill in drive it had a transmission overheat light come on.

After this it was put into 2nd for steep hills and did not have a problem.

In fact I was very impressed by its ability.

The 8 speed Amarok auto with no transfer case is getting very good off road reviews.
