Transfer Case Query

[doogs911]

Changing from high to low and locking the diff in my '97 disco seems to require a bit of braun and I'll have to put the transmission (auto) into drive and reverse and back into neutral to get the load off the transmission. Only recently has the vehicle started to be used off road because prior to me inheriting it, all such duties were left up to our '77 rangie, so could this simply be the result of lack of use or is it perfectly normal?

Thanks.

Check the vehicle handbook for the correct method of tfr case engage/disengage before you take any drastic action.

I think your experience is "normal". Auto changes the way you do it!

If it's been in high range non diff lock all it's life it will be a bit stiff. You'll probably find it will loosen up the more you put it into the other positions. Even then they can be a bit temperamental.
Don't force it you'll only break or bend something.

[doogs911]

It's not so much the fact that it's stiff that annoys me but the fact that I'll pretty much always have to change into drive and reverse etc before the lever will go anywhere.

I agree with WayneP, I think that it's just due to lack of use. In time it should become less problemmatic.

Mine was the same as it had a pampered life before I bought it and never left the bitumen. It has loosened up over the last year but every now and then it will need to be slotted into drive to get it to engage.

Rightio, thanks.

ahh sluge boxes... try this...

just before you stop select nuetral and let the vehicle come to a halt while you maintain effort on the tcase selection lever that should quickly sort out the low high thing... ITs not the right way to do it but so long as you keep the main transmission in nuetral and only do it at only just moving speeds you will be fine so long as you dont overdo it. Once it frees up move back to doing it properly.

[doogs911]

Will do. Thanks.

in a manual it was much easier to just slightly release the clutch,

sounds like your auto might need it too
(though mine shifts fine,,)


i put something about this in The Good Oil,,
I think,,,

Maybe different vehicles require a different technique.

When I first bought mine at 112k, I'm pretty sure it had had little offroad use and certainly no serious 4WDing.

I tried all sorts of things to get an effortless shift to and from low range, like easing the clutch out.

What works best for me is to try to organise it so that I drive the vehicle a few cms either forward or back so that it will rock back when I hit the clutch.

If I nudge the lever in that split second when there is no load on the transmission, it is almost like the proverbial hot knife through butter. The only resistance is obviously just the ball and spring that locates it in each position.

It works even better since I tightened up the screw I had trouble with here http://www.aulro.com/afvb/technical-chatter/65595-transfer-case-problem.html#post834983

I'm convinced that on mine what works is ensuring there is no load at all on the transmission.

Of course, as I'm sure Blknight.aus would be keen to point out, having a slush box instead of something you have direct control over, might require a different technique.:p

[doogs911]

Yeah Blknite.aus I tried what you suggested and it worked like a treat.:) Hopefully it starts to loosen up with more use.

That is the way I have always done it and I learnt the technique from the driver's handbook ;)
