Have recently purchased myself a My16.5 Discovery 4, and slowly going through replacing fluids etc. It had an oil change the day before I picked it up, and from the service history, I would suggest that most other oils should be changed.
Looking at the filter/pan for the auto transmission has got me into a tail spin.
There are so many options with sooo many different suppliers.
I know Repco did a Ryco one, is there going to be anything wrong with this filter/pan?
Is there a recommended filter/pan?

I plan on using LG8 as the fluid, unless anyone could suggest something that is on par or better?

I plan on doing Transfer case, and diffs at the same time.
Just out of curiosity, does Royal Purple do something I can use in the diff and transfer case? (Transfer case I was going to use their syncromax that i've seen other using)
Open to other alternatives if they'll save a few dollars, but not opposed to spending some money to keep this beast running nicely.
