I did a lot of searching on the subject with, initially, Ashcroft Transmissions telling me to use Castrol. I then actually contacted Castrol. Their reply " We do not make a fluid suitable for the Jatco Box"
Apart from Land Rover, several Japanese cars also have Jatco boxes and Jaguar have also used them, They all probably sell The N402 but it will be in their own branded pack as is the Rover Fluid.
I have heard that Jatco boxes operate at high temperatures. Whether this is true/different to others I don't know but i am informed that N402 has additives not present in other brands.
On reliability/cost/preventative grounds I intend to change every 30000 miles, not 60000. It is not prohibitively expensive. (about £40)
Unless you are completely happy that you can carry out the change as reccommended I would strongly suggest you take it to a GOOD auto specialist. The temperature on refilling is fairly critical.
When you say temperature on refilling do you mean engine temp or does the fluid need to be of a certain temp? I have read how to do it and it is easy to get to the drain plug so it should not be a long job once up on axle stands. I am not keen on specialist prices to be honest.

Can you explain what I have to do that is critical? I have read the how to pdf from here and have details from the workshop manual too.

Simon.
