I know this has been discussed before and I've done a search, however I've struggled to find a conclusive answer.
I've noticed the ATF fluid is below minimum on the Rover. It is due for a LONG drive over the next week and a half (France, Switzerland, Italy, Germany) including mountain roads, as such, I'd like it in as good as health as possible.
Don't intend to drain and refill, just top up - which shall I use? I know it is stated if the wrong fluid is used - the gearbox will explode causing death, destruction and likely to precipitate WW3. I would not like that responsibility on my shoulders.
(The difficulty is of course, knowing what is in there already).
