I had mine fail last December at 51,000 miles. Dropping the transmission to replace it wasn't overly complicated (just busted my knuckles a few times trying to get the bellhousing bolts off!), but I'd definitely consider changing the clutch while you have the transmission down. Z1 Motorsports makes a beefed up CSC and they also have a CSC delete kit. I went with the beefed up CSC and the clutch definitely feels firmer with a slightly lower engagement point.
