I'm a new fan of Spectro 6-speed tranny fluid. I was running Redline and after reading a few threads posted by Glider, I decided to try Spectro this time. SO MUCH smoother and quieter. BTW....it's in a 5-speed. The GL-5 fluid is not over-kill in a 5-speed. It makes it that much better. Glider, thanks for the threads of wisdom.
