Low range climbing issue

[silverfox1111]

Gday all.
Had an unusual issue when climbing steep hills in low range recently.
Was climbing up the hills to get into & out of Bendethra camping area (duea national park) which has long steep climbs with pinches up to erosion mounds. Had the jeep in low range & first gear. The jeep would continuly bog down then rev up again & spin the tyres. Tried in "auto" & "rock" settings but no difference.
Thought it might have been loosing traction first then traction control coming in, but i dropped some more tyre pressure out & it made no difference.
Anyone else experienced this? I've climbed hills nearly this steep before but didn't experience this.
Thanks

take it out of low range and see the difference . remember low range you can only do 40

I doubt it could of been done in high. Had about 1.6T of camper trailer on on the way in. Did try the hills without the camper & was the same. Would of been doing no more than 20km/h then it bogged down to about 10km/h then would rev up again, then repeat till i got over that climb.
Are you sure about the 40km/h limit in low? I don't think there is a limit for low range, unless you run out of revs.

i had the exact issue in sand dunes climbing steep hills . took it out of low range and kept it in sand mode and had no issues

Not sure about the 8 speed but every other 4wd I have had ran out of puff at about 40-50km/h in low range. Would be interesting to see in Jeep.

Silverfox1111 have you dealt with traction control in a new vehicle much before. Gone are the days of once you spin a wheel you loose tractions. You need to get the wheels spinning to get the traction control to work to push you over those bits. You need to stay on the accelerator and keep spinning. Kind of backwards thinking from past as you would think that would start to chew the ruts out even more spinning the tyres all the time but that seems to be the way to do it.

Out of a matter of interest did you try it in 2nd gear low?

There is a speed limiter in low range set at 40kmh. I had similar hesitation issues early on but these went away after some software updates

I've had the traction control come in at other times & know that you need to keep your foot into it & let the computer sort it out.
On the way in i thought maybe i was loosing traction & the braking part of tracion control wasn't enough so the computer took away engine power to get traction back. But i doubt that was actually happening cause i didnt hear the noises that happen when the traction control usually comes in & on the way out i dropped an extra 4 psi out of all the tyres to give more traction but it atill happened.
What it felt like was going up a steep hill in, say, 2nd low, the hill is to steep for that gear so the car slows down then changes back to 1st low. Only i was in 1st low already. The Jeep would speed up then it would happen all over again.
By the way it's a 5 speed.
