Dave, the dealer replaced my fluid ONLY about a year or so ago (just under 100k miles)....when would you suggest replacing everything? Can I wait until 150k and then do fluid and filter/pan? Or should I do it sooner?

 

ZF (the manufacturer of the transmission) sent a letter out to many of the shops that service them, indicating that they (ZF) recommend you service your transmission every 60,000 miles.

A fluid change will only give issue with an already existing failing transmission. A healthy transmission will benefit from the fresh fluid.

 

You'll be fine to wait til ~150k. Just be sure to keep an eye on it for leaks, and any shifting issues until then. When you have the pan changed, replace the connector sleeve with the new style, even if yours isn't leaking right then.

 

I corresponded with a technician at ZF UK and was sent several documents confirming their new recommended service intervals. One of the documents is called "Accelerate Bulletin".

They state:

"ZF recommends oil and filter changes after 50,000 to 75,000 miles to ensure optimum performance."

 

Interesting, who sells that stuff? I might try it, i've got a transmission just in case!

I'm glad they finally took my advice, i've been saying 60-75 for at least 2 years or more.

 

I had the transmission fluid, transfer case fluid and differential fluids changed on Thursday.

My Land Rover authorized dealer, MCL Motor Cars, discouraged me from performing the service so I took it to a private Land Rover enthusiast shop that appears to be much more capable and better informed than the authorized Land Rover dealer.

The service is transformative!

Vehicle shifts are silky smooth. The gear hunting/surging is gone. Fuel economy is better. When climbing hills at highway speeds the vehicle shifts far easier into appropriate gears.

Simply a completely different vehicle to drive.

 

yes! My lr3 v8 has 130000 km so yesterday i changed my transmition oil 9.5l i put motul mult atf synthetic by flushing i not changed filter, ill change next time, my car is great and better soft! Tomorrrow ill change oils of gear box and diffs also.

 

I have a 2007 LR3 with 91,000 miles I just completed the transmission oil service my transmission is now slipping and ruined this was not happening before the service I highly recommend not doing this.

haveQUOTE=ghtaylor;407326]I have a 2005 LR3 HSE with approx. 60,000 miles.

After reading the many posts about flushing and changing the transmission fluid I asked my LR dealer if I should do this.

I was told that they don't recommend it and they say that LR does not either.

They informed me that doing this can cause the transmission to prematurely fail.

They said that the particulates in the transmission that gather over time from normal wear and tear actually assist the clutches to engage properly and that the computer adapts to the accumulated particulates.

By removing these the clutches will not engage as well causing slippage and gear change difficulties.

Are there any seasoned LR Technicians ( Dave ) that can offer me some advice/guidance?

I was about to have this done now I am afraid to.[/QUOTE]

 

[/QUOTE]If it is 91,000 of city miles and the first tranny oil change since new 13 years ago, then yes, clean oil might show up the wear.
At the same time, all might be fine but delay another couple of years, and not so.

ZF recommends every five years and I believe it is not just so they can sell oil. You might note my previous post #2 where I make some comments about oi changes.

I now have about 230,000 miles (370,000 km) and am still on my first tranny but about my forth or fifth oil and filter change - and I do not like paying for it as it is not cheap.

One does not get the LR dealer to do the oil change - they do not know how, and yes, it never works for them either as the techs do not ever get the experience required.

You have to go to some greasy dirty place most often found in the East end of town where their yard is filled with dead Mercedes, BMW and Audi's. These guys are usually not afraid of ZF transmissions. Also there are now Ford shops that understand our ZF as the trannys in their newer pickups are license built ZF units.

The link below is to a number of files on the ZF tranny we have in our LR3s. I note one of the files has over five thousand views - not many for YouTube but alot for Land Rover.

buyer - Its been established that Motorcraft Mercon SP XT-6-QSP is the same spec as LG6. 12 quarts is about $90 USD. And since a full change is not usually possible with DIY, you usually use just 6 to 6.5 quarts.

14TMoney - It actually sounds like you are short on fluid. You should have added about 6 quarts. I just did my transmission this year and just a couple weeks ago I did my neighbors. No issues with either. Mine had about 150,000 miles and his has 180,000. The procedure is to replace the filter/pan/etc. Whatever work needs to be done. Then open the fill plug on the passenger side with the vehicle on very level ground. Then you add about 2.5/3 quarts slowly until it drops out. Then you start it up to bring it up to temp while adding another 3 quarts. It should start to flow out slowly until you get a drop every couple seconds or so. With the vehicle still running, of course, you reinstall the fill plug.
