That's why I never answered..... There is no external test, beyond taking the car out and beating on it severely, and seeing whether you get any slippage... If it grabs a 1st-gear 3600rpm launch, and it holds 6th-gear firm under full-throttle.... Then it's fine... How LONG will it be fine??? No telling, beyond looking at your odometer, reflecting upon your driving skills, and forecasting from there...

Or, drop the tranny and look at the clutch... Which, by that point, you may as well drop in a new performance clutch while you're there.....
