Thread: Decisions, decisions, which Disco do I choose?

Nope, that's when you accelerate down hill although rear diff locks are also nice

Even on the steepest ring clenching decents I have never had the truck run away in first low in the manual. I have in my auto, and have seen D2 autos do it. Autos are better uphill, they are better in sand (as long as they dont overheat!!) but sorry for my money I will take a manual in low first downhill any day over an auto. They are simply slower and dont run at all. The only time I have HDC come on on hills so steep I cant walk up them is where the truck falls into a hole on the way down - one wheel and it senses a speed difference and gives a very quick brake grab and thats it.

Each to their own I suppose. 90% of D2's sold here would likely be autos so I dont expect many people on here would have experienced the down hill joy of a manual D2.

No but the d2 auto with the torque converter locked in 1st low in M mode doesn't run away either like I said, I've used it on hills so steep you had to actually drive down them or the back started slipping out. Had that in manuals too that said, its handy to just leave a manual in a lower gear.
I don't use hdc anyway

If a D2 auto is running away on a butt clenching downhill descent then it's being driven wrong!

Put it in low range. Does NOT work in high range. Lock the centre diff (if your off the tar). Engage "M" mode (Sport/Manual button). Put the stick in position "1". Torque Converter locks up when the engine revs rise to 2000rpm (raised to 2000rpm by the wheels driving the gearbox, driving the torque converter, to drag the engine rpm up to 2000rpm). Once the engine revs reach 2000rpm the torque converter locks up (and it ONLY locks up in low range on over-run, never under throttle) the drivetrain acts exactly the same as a manual gearbox with a clutch ... solid. No slip. If you touch the throttle, the torque converter will unlock. You CAN use brakes to aid in slowing the descent without the torque converter unlocking.

No HDC required. But you can add HDC ontop of the above if you wish (it is after all just the brakes being applied to maintain a given target speed).

Here endeth, the lesson

I don't like it. Sounds like a pain to get it locked up....the manual is at idle revs straight off and What happens if you have to accelerate for a split second?

Cheers

Sounds complex but in practice is quick and painless. If I'm driving that sort of terrain I'm already in low with M mode engaged driving it like a manual anyway (M mode low range stays in whatever gear you select regardless, so you can lope along in a high gear with low engine revs). From a standing start if I'm in 3rd, it will go 1st very briefly, then straight to 3rd and stay there until you come to an almost standstill.

If I have to apply so right foot downhill ? ... Got me there, have never had to do it !

I've been a manual dude all my life and the D2 was my 1st auto ... under duress I might add ... quickly learnt I preferred it to the manual off-road due to being electronically controlled which gives me much more control of what the box is doing, unlike the older style hydraulically controlled boxes of yesteryear, so I made it a mission to learn how to drive it properly and adapt. Glad I did.

I've been out with others driving D2's who didn't know/listen and following them on the big downhill runs they stayed in high range with the stick at D, riding the brakes all the way, slipping and sliding and looking very out of control (very dangerous in some spots) while I drove setup like outlined in my previous post, and just walked down without touching the brakes once ... They got to the bottom quicker I got there safer with less risk to the vehicle and occupants

... just wish it was a 5 speed !
