Thread: For the automatic fans

I am not an expert on auto trans by any means but l think it goes like this:
Run away is caused due to slip in the fluid coupling. This presents a problem if the surface is slippery, using the brakes will quickly provoke wheel slip and result in loss of streeing control.
As described above, the fix is:
Select low range first gear on the flat, left foot brake and apply throttle with your right as normal until the engine is balanced at about 1500rpm or there abouts against a resonable degree of braking force.
When the descent begins, keep your throttle where it is and modulate your left foot braking to maintain the 1500rpm you set on the flat. keep an eye on the tacho and one on the trackahead. The extra engine torque makes it harder to lock the wheels under braking. If the wheels do lock, reduce brake pressure until steering control is regained.
Yes, you will be going a bit faster than normal.

I may be wrong here so feel free to correct me if thats the case.
P.S. I drive a manual

cheers

Can't say but the later D1 has the same box and T/Case, LT230.

What truth are you referring to? As to the facts, you have presented us with very few.

How good were the tread on his tyres? Were they caked in mud (maybe more so than the others?) Did he take the same line as the previous driver? Did he try steering down a rut? Was he trying to use left-foot-braking? Did something distract him at a crucial moment?

So far we have been presented with very little facts and when we offered possible explanations as to why it happened we were accused of living in a dreamworld.

Next time I won't bother trying to help or offer advice, obviously it's not needed and anyone who posts such a topic is obviously baiting.

Thought I'd give my uninformed opinion.

Rangieman, your mate has, you say, years of experience with Series Landies. So I'm guessing manual? As a driver of a manual vehicle, what I've taken out of this discussion is that the techniques required for auto driving are quite different. It's no criticism of him to say he may not have known the correct techniques.

On the speed front, as a kid in PNG the locals always ran down hills rather than walked - they said you slip too much if you take it slow. If you think about gravity it makes sense - the slow vehicle is actually being accelerated (by friction) vertically. The faster (or strictly, accelerating) vehicle is placing less force on the ground.

Would be interested in a head-to-head, also ABS Vs non-ABS.

Just a question, not an argument

I'd suspect competition vehicles would be running somewhat modified diff and/or tranfer ratios which would help counter the effects of the auto.

At the end of the day I think all the suggestions on how to drive around the downfalls of an auto are the key answer.
A manual is almost as idiot proof as putting it in low-low and feet off everything - almost - whereas the auto requires somewhat more technique.

Whos trying to bait who now dont accuse me when you dont know me
and for the facts there was plenty of advice given by the pro auto mob on that SO little facts
i didnt accuse any one of living in a dream world if you took it that way im sorry
some of you guys realy want to push it that little bit further
we are supposed to be adults here so lets act it and cease the blame and shame game

his tyres were a chunky AT he did sit in the rut as i advised him and the braking thing i will contact him and find out

as i said in the earlier post he has owned this car for 6 years and has done many a trip i have never been in the situation to watch him come down a hill befor
so maybe he is aware of it and it doesnt worry him i dont know but with 5 people watching him they all said no way to auto,s

Not saying I'm about to buy one, either, rangieman. Maybe when I could afford a D3 though ...
