REDLINE ATF or D4 ATF??? In a T-5???

[cjhenry01]

What should I use in my stock T-5 tranny? I called the Redline's Techline and they said to use the regular ATF and not the D4. I know some members use the D4 ATF. What is your take on this?

I have the D4 atf in my car, whats the difference between that and regular Redline atf? I thought they were the same.
