Disco3 experts?

[F.J.]

Since starting my new job and only having one place of work to drive to rather than covering the uk, I decided to treat myself and bought an auto 08 plate disco 3. It's a cracking motor but has since developed a transmission problem (I believe) as it hunts and the revs raise and lower as if there is friction/no friction along with a change in tone of the engine.
I took out a warranty on it as after all it is a Land Rover but I doubt this will be covered as the gearbox will be seen as a serviceable item??
I have it booked in at Land Ranger in Atherton next weekend for a check up and I will also get them to do a full service and gearbox flush.
Anybody with experience of such beasts Who may have an idea of said problem?

Thanks

Common problem, torque converter lock up issue. Gearbox flush may cure it depending on how bad it is. Putting some Dr Tranny can sometimes be a temporary fix and is worth putting in when the flush is done. Are they actually doing a flush or changing the oil? A flush involves linking into the oil lines between the cooler and gearbox and will replace 95%+ of the fluid. Make sure they use the correct spec fluid. Flushing at home is possible, I built a set up with a pump. Be aware depending on the mileage/condition of the box then sometimes a flush can actually make things worse as the new fluid disturbs the debri. Depends on who your warranty is with, some will pay out on torque converters.

As already said torque converter make sure you catch it now or it will take the gearbox with it

A normal gearbox drain will only change about half the fluid it needs to be done by a specialist land rover garage that knows the trucks

I'd suggest changing the sump for the type with a removable filter at the same time

I was just about to say is there a filter in it.

There is a filter but that won't fix the issue and the reality is there rarely any stuff to be concerned about in the filter. It's common to swap the sump for a metal one used on BMWs but I don't see the point. The main reason for doing it that you can remove it without take the crossmember out.

This site is very helpful for D3 problems. I have a look to see what goes wrong with them since getting a D3 but haven't had too much of a problem with it yet.
