Redline 75W140ns fluid; yay or nay?

[AlphaAssault]

I just got some Redline 75W140ns synthetic transmission fluid, and was wondering if anyone has any input on weather or not this stuff is any good. i know its a little on the heavy side, but i prefer heavier trans fluid; im more curious about whether or not it is compatible with our SYNCROS or not. has anyone tried this fluid, and how was your experience with it?

The weight isn't what makes it incompatable with the syncros. GL-4 is what you need. GL-5 is bad. It isn't formulated to be used with yellow metals (aka. our brass syncros)

oh. i thought synthetic fluids, even if GL5 rated, didnt contain the stuff (sulfur) that corrodes our syncros. only the old dyno GL5 eats our syncros, i thought.

I used Mobil 1 and it was very crappy after a few months. Used it in winter bc it was 'lighter blend'. Before that I think I used BG2 and a bit of RL HD?
Now I'm using AMSOIL - Synthetic Manual Transmission and Transaxle Gear Lube 75W-90 (MTG)
Seems to work fine, but I haven't raced the car or taken it to the track, plus I am not really driving the car.
