I know this is SERIOUSLY

But in getting ready to do a clutch in my LT4, I've been getting everything together in my head, and asked a few buddies about fluids.

Here is my thought. I hear positive and negative about TWS, and judging by the owners car's, it seems most of the positive comes from black tag guys, and the negs from blue's.

Wanted to get a larger cross section on this theory, and MAYBE, put an end to the debate ...




for this week.

the Black tag = German made... shorter tooth gears.. makes more of a whine... but stronger
450lb rating
the Blue tag US made longer tooth gears... makes less noise.. weaker 400lb rating
same clutch... Different Through Out Bearing....

black tag owner here who doesn't like TWS. Maybe it's the other way around?
