just hit 30k and changing tranny fluid which should i use?

probably a repost cant find it plz suggestions?

 

I would say switching to Redline Synthetic, but as they do not offer the oil in the weight and viscosity that our transmissions require you must mix 2 qts of Redline MTL: 70W-80 and 2 qts of Redline MT-90: 75W-85 to make the necessary 75W-85.

Transmission, I believe only takes 2.9L (or 3.25 US qt)

If you just want to use Nissan MT oil, get 75W-85 AND MAKE SURE IT IS API GL-4 **NOT** API GL-5

Knock yourself out. It's a long read.

Read through the entire thread before typing another post regarding transmission/differential fluid.

 

i ran royal purple and motul...i went back to nissan oem fluid, its synthetic and i change it every year or 30k miles so it works fine
