I did my fluids on my 2008 LR3 a while back at around 80,000 miles.
The old fluids looked fine as well, but I just didn't want to risk it.
A transmission failure on this truck would immediately mean I'd need to sell it, and I'd lose loads of money. There's no way I'm willing to put a $6000 - $7000 transmission replacement in this truck. I love the rig, but no way would I put that into a failed part repair. These trucks just don't hold their value well, and I don't know that I trust the vehicle to last me another 160k or whatever I would expect from the new transmission.
I did not pay a shop to do the work, I did it myself at my buddy's shop (he's an ASE certified tech), so that was a huge bonus for me.
Moral of my story: Better safe than sorry was my motivation, and I'm glad I did it. If nothing else, I now KNOW that my trans fluids and filter are good to go for at least the next 90k miles.
