Landrover Discovery 2 TD5 automatic

[LewMac13]

Hi all, I’m new to the Landrover scene.

I have a Landrover Discovery 2 TD5 automatic (1998)

I was driving on a normal road in wet conditions and went through a puddle on the road, about a mile down the road I noticed that my clutch was slipping, the revs where going high and the car wasn’t moving, has anyone got any ideas to help? Thank you in advance

Sounds dumb, but when I picked mine up from the seller, on the drive home, I moved the gear selector to change down and exactly the same thing happened, no drive to the wheels. After a while I realised the Transfer box lever had jumped out of gear. As soon as I put it back into high I was moving again.
So simple but it took a while to notice it, especially as I had not had an auto 4x4 before.

...about a mile down the road I noticed that my clutch was slipping, the revs where going high and the car wasn’t moving,

I'm wondering how would the clutch slip on an auto? unless you mean clutch packs within the autobox but that would not give such sudden symptom and should trigger the M+S warnings... make sure that the transfer box didnt drop out in neutral

.. which is more or less what I thought might have happened, unless somehow his autobox has jumped into neutral. Assume he has tried to move off in all gears, low box, etc?

Thank you for the reply’s, I have done a stall test on the torque converter, that seems fine, it drives fine when I’m driving normal, when I go to put my footdown like joining a motorway or dual carriageway it gets over 2500 revs and then starts slipping, I have checked the gearbox oil lever that’s fine

I am okay with mechanics but not that confident with auto boxes

I am thinking the clutch pack but I’m not too sure with auto boxes

If it passed the stall test the autobox should be OK... so do you mean that at 2500rpm the rpm starts rising above 3000 and it doesnt accelerate? cos then it should have not passed the stall test... how does it start slipping... isnt rather a ''kangarooing"?

So, starting off it goes up normal so as the revs go up the the speed goes up, but say if I put my footdown the revs go like 3000 plus but the speed stays the same, also if I put is in sport mode I think it is so the green (S) comes on the dashboard it has no power, I have scanned the car through the OBD port and there are no fault codes

Thanks for the reply

I understand but in these conditions it should fail the stall test and give you theclutch slip rpm

This is what I followed, I got 2600 on my rev counter

I think there was more than 20*C outside so i'd say that it's very close to the clutch slip limit and according to the symptom i think you was spot on with that and your autobox is fubar

Fubar? Do you have any idea where I could get a clutch pack for a td5 autobox?

I'm dumb with pure mechanics so if you think that replacing the friction plates would help here you go https://www.ashcroft-transmissions.co.uk/diy-rebuild-kits/zf-rebuild-kits/zf-master-rebuild-kit.html

Buy another gearbox from a breaker like Heathy

Have you changed the auto box oil? Apparently it comes out black and burnt if the clutch pack has worn out and red and dirty if all is OK. I've not direct experience, but this is what I have been told.

Cheers.

Just a general auto box question. Would you also get clutch slip in "4th lockup", i.e. is the lockup only for the torque converter and the clutch pack would still slip, or does it lock "everything"?

If it is only the TC, do you still get clutch slip during lockup?

Cheers.

If your asking me this question I am not too sure

Where is the best place to get a disco td5 auto box from?

Sorry, no, not the first part, but maybe the second part, do you get clutch slip in lockup (lockup is generally over 50mph)?

Cheers.
