extactly which redline ATF tranny oil do i need for a max with 45000 miles: high temp, dex III, d4, c+, racing?

 

I would say the D4 atf based on the info on their website. Why don't you consider Amsoil universal ATF? Amsoil will last 2-3 times longer than conventional atf.

Redline will not stand behind the product (based on filtration) beyond 30,000 miles or Nissan's recommended interval for service. Nissan is not clear on when to change the atf. Nissan says check atf every 30k; it never says definately change the atf in my owner's manual.

Redline is a great product, but the value proposition for Amsoil ATF is more compelling. Plus there are .org dealer that will give you a discount on Amsoil products. I would take 60,000+ miles versus 30,000 miles anyday.
