4Low Lock in Auto Box
Good day

Some advise from you that have driven these vehicles for many years

I recently bought a 2004 GLX, 3.2 Auto

So far I am very pleased with the vehicle, enjoy the ride quality, even the consumption is above par I hope, 9.4km/l, then 9.7km/l, and then 10.1km/l

What I would like to ask. Coming from manual boxes, I know that, when going down a steep hill in 4wd, and low-range engaged, the engine will assist to brake the vehicle, but what to do with the auto box now. I tried to leave in in the "D" mode, and this caused the vehicle to pick-up-speed. This I can understand

But when I moved it over into the "split" section, and "locked" it into 1st gear, it still happened

Do I miss some special gadget that I have not found as yet, or is this normal, and I just need to get used to having my foot on the brake more?

Many thanks for the advise

Regards

Hi Andries,

Pajero's don't have "Hill assist" or any of those gadgets, but selecting 1st gear in low range should definitely cause the vehicle to run against engine compression. You should see the revs climbing on a downhill, especially on a steep downhill, and you would have to use brakes to assist. If the vehicle picks up speed without picking up the revs you may have a problem. Hope this helps.

The Pajero low range reduction is only 1.9. Most other 4x4's have a lower reduction so of you're comparing to other 4x4s then you will notice a difference.

Hi Andries

I experienced the exact same thing as you did, when I did my first downhill.
it was a :o experience and I ended up tapping the brakes all too often....

However, with this being my first Automatic 4x4 vehicle I ended up re-reading a portion of the manual and realised that I had not successfully locked the vehicle in 4LLC

When transitioning from 2H to 4H you can simply reduce speed a bit and then push from 2H to 4H.

I believe you can do the same when moving from 4H to 4HLC, though I normally stop completely.

When you then transition to 4LLC , you need to stop the vehicle completely and put the main box into "N" before making the shift.

If you then "hold" the vehicle in 1st or 2nd Low gears you can clearly feel the difference as the vehicle runs against it's engine compression.
Re: 4Low Lock in Auto Box
Light "feathering" of the brake is usually enough for me going down steep downhills when in tip tornic 1st.
If in "D" it will pick some serious speed in to 3rd gear then you will have some fun on loose stones

Also on uphills I usually stick in in 2nd or 3rd depending on the incline because the gearbox likes to go sit in 3rd when in low range and then you might lose momentum on the up hill.

Very good explanation.

Re: 4Low Lock in Auto Box
Thank you to all that have responded

I will make sure next time that 4LLC is completely engaged, and as you mentioned, the vehicle must be in N to be able to do this

Wishing you all the very best for the holidays, travel safely
Re: 4Low Lock in Auto Box
Even then, I would start to practice feathering your brakes. I have never been able to go slow enough with engine braking to not use the brakes.

Agreed.
But there's a huge difference between running "freely" downhill and running against engine compression...

:lol:
Re: 4Low Lock in Auto Box
I can confirm that everything works 100%

Previously my dad never engaged 4LLC, stil had it in 4HLC :lol:

Now, he is smiling all the way, power and torque galore

I agree, you still need to have your foot on the brakes when going downhill, just to keep the speed down, but there is some engin braking taking place

We experienced some wheel spin going up-hill over a bit of axle-bending. We did not force the issue, just rolled back slightly, and tried again

The question I would like to pose, does this Gen 3 have some sort of traction control, and would brake the spinning wheel, or would the wheel-spin continue as long as I should have my foot on the accelerator?

Thank you again
