I am about to change my trans oil and rear diff. What kind of oil do you guys suggest and what grade of oil?

I use Redline gear oil and it works very well. Use Redline 75w90NS in the gearbox and Redline 75w90 in the rear diff.

I used red line also. Works like a dream. I have about 7k miles on it since it changed it and it still looks new.
