Thread: Disco 3/4 Automatic Transmission FAQ - 6 Speed

Do they have a filter inside the transmission, as most ZFs do? If so I strongly recommend regular filter changes, as failure to change it can lead to transmission failure and a big bill.

They do have a filter inside the pan. I've been looking into installing an extra filter up near the oil cooler that can be changed easily, and also a possible oil sample point as well while Im in there making extra lines etc...

This post I just found online explains it quit well.


Land Rover / Jaguar ZF transmission servicing and faults - Pickards Automotive | Car Service Centre | British and European Specilists | Melbourne

I was quoted 5000-6500 for a trans recon

After reading this I spoke to Michael and then had him service my D4 transmission. Very satisfied with the service and the cost of about $800/

So, pure and simple - 189,000km on the clock of my Disco4. Is it too late to do the pan & fluid change, and if so, any recommended shops near Oakleigh Vic to do it?

In case someone is interested, I got the conversion done at A&B Automotive Remanufacturing in Dandenong South. A very impressive facility anf their service was top notch. All up cost was $990.00.

You only tend to hear horror stories on the internet, often without getting all the real world facts.

I flushed my D4 transmission this week, first ever transmission service with 210k & all good. These are very well designed transmissions, can handle a huge amount of power & abuse. Yes, it is smoother & more positive now, but keep in mind the amount of folk who have no idea & keep driving while adhering to the Land Rover service schedule without major problems.

However, I do agree that regular 50k servicing is whats needed for a long transmission life. I don't want horror stories causing people to push for a rebuild when it is not required.

The trans cooler is under the forward most cover under the front of the vehicle, the nearside pipe is the one to remove & collect the old fluid when pumping out.
When changing the pan use the traditional 'allen key' type of torxs, this will allow access to all the screws without major issues.

Thanks Diesel. Report from A&B was all positive, saying no appreciable wear evident.

I plan to just take it back to them each 50,000km and get it serviced.

So ah, just wondering how many people have a new pair of these, and their car still vibrates between 1400-1800rpm, mostly under light load?

In saying that, I'd say they we're knackered anyway because it was shaking through the steering wheel at 100km/h too, and now doesn't.

Which leads me to my question, is a slight vibration okay or a sign of total failure imminent?

It also seems to bounce between 1400-1500rpm at 80km/h on a slight incline.

Thanks
