DIFF LOCK v ATC????

(1/2) > >>

Range Rover Ron:
Hello all,

I've got a 1994 RRC which has no diff lock, it has the automatic traction control system.
There is a pump on the brake system that allows the brakes to be operated when detectors see one wheel spining faster than the others, (at least that's how I think it works!)

My gearbox has a little argument with me when I shift from 1st to 2nd gear,
it also slips out of low 2nd gear when off road so I'm thinking of replacing it.

What I'm wondering is what would happen if I fitted a standard RRC/Disco gearbox that has a difflock on it?
When in the sticky stuff with both diff lock and ATC would I create an awesome off roader?
Would the two systems counter-act each other?
Has anyone done this?
Any side affects found or anticipated?

The later, non diff lock gear box is probably hard to come across so this might be the easiest way around my problem,
any ideas any fellow M-C'ers?

I have a 1998 Disco Td5 which initially only had TC fitted as standard.  Whilst it was good, it did still lack in certain situations.  As a result I retrofitted a CDL and tweaked the ECU's so that both would work together (unless I decide for them not to).

The upshot is that with both working it takes alot more to get the car stuck than it did before (although I can still do it with comsumate ease).

Obviously this applies to the Disco 2, but I can't see your situation being that different.  Go for it I'd say!!

I think what your talking about is the borg warner transfer box that has a viscous coupling fitted instead of a manual centre difflock.  When one wheel spins too fast, the liquid in the viscous coupling seizes up forcing drive to split to both axles.

Some models also have a version of traction control using the ABS components.

If your jumping out of gears, I'd suggest that's your gearbox at fault rather than transfer box or TC...?

Ron, he's right.  The '94 model was available with ABS, if this is fitted you could add ATC which only works on the back, if one wheel is spinning it will lock it up briefly.  The system will not run indefinietly as the brakes overheat.  It's no substitute for a locking diff.

Tiy centre diff is the viscous Borg-Warner unit, so it's already fully automatic.  Whilst there is some mileage in fitting a Disco style LT230 in there for pure off-roading it is not as good a unit on the road.
