Like ive said before, i went through about 4 gearstacks, 1 running an ACT Extreme PP w/ 6 puck sprunk disk and mobil 1 75w90, I went with a twin disk and broke one stack every month for the first 3 months, first stack i ran mobil 1 75w90, second stack, Redline MT90, 3rd stack Redline HD Shockproof, Put the 4th stack in with Valvoline conventional 85w140 and the stack went 9 months of abuse at even more power than the 3 previous stack saw. All stacks saw over 400whp daily, 500-550whp on race gas on some weekends and track runs. The trans is still being used in a buddy's car with over 350whp without issues. Again no changes to driving habit. The gears would always break on the street during hard quick shifts into 3rd or 4th, never just rolling onto the throttle in gear. I switched to the Valvoline and did multiple quick hard shifts on the street whereas before it would strip the teeth almost every time and it held up just fine to the torture. I use it in my 6 speed trans as well. Its a night and day difference over every other oil out there. Shifting is soo much smoother and especially at high rpm quick shifts. Trans is quieter during normal driving and you can just feel the cusion on the gears when you change gears and let the clutch back out. There is no banging or anything on the drivetrain whereas before you would always feel that jolt on the drivetrain.
So far everyone that ive gotten to switch to it has absolutely loved it and soo far not one broken stack. Coming from people that broke gears like it was cool before. Most all over 350-400whp, some in the 500whp range. So take it as you will but its been proven. Its not a gl-4 fluid either but it doesnt matter. Dont be worried about that. Its not gonna eat through syncros any time soon. Maybe over the period of 10 years you might have syncro wear from it but come on who cares.
