i'm thinking since you got the new clutch that grabs like a mo-fo, they will blame it on that and not warranty the parts since they aren't OEM. Good luck man.
ie. "your clutch(aftermarket) is so high performance/grabs so hard that when you jumped into second it broke something(stock transmission)"
in their eyes: aftermkt clutch--->breakage of tranny--->not their problem...
good luck man
