I know people do this oil change and report positive changes, but my understanding is that is sealed for life according to LR, so wonder why you state ‘well beyond recommended’. Interested in where this recommendation comes from as mine is a similar age, but under half the miles.
Thanks Gary

I've done so much reading on this.
From what I've found ZF themselves recommend an oil change around 75k and it seems from a lot of independent service companies that work on them say the same. Someone might correct me but Land Rover stated sealed for life so it wasn't there problem later on.

Understood. Thanks for sharing this. I’ve done less than 60k miles and the car is coming up to 9 years old. Gear changes still very smooth (that’s done it !). Gary

ZF never built any transmission with the recommendation "filled for life"

I spoke to ZF over 25 years ago and they told me then that this was a decision taken by car manufacturers themselves, and against the recommendations of ZF. I remember feeling very angry at the time about this seemingly deceptive advice from the car makers. Since then I completely ignore their service interval recommendations and form my own based on common sense and a lifetime of experience.

If I remember correctly the recommendation from ZF at that time was 60k to 80k miles for an oil and filter change, and every 40k miles thereafter for a long transmission lifespan. Thumbs Up yµ (idµ - eAµ) ψ=mψ
