I know the 340 has been out about a year now, but was wondering specifically about the 6MT platform (tranny and clutch) and whether or not any owners who've gone the JB4 route have observed clutches or gearbox problems?

Coming from the Subaru world, the Cobb stage 1 tunes were pretty safe on both the WRX and the Legacy GT platforms, but on Stage 2, the Legacy GTs were commonly observing clutch slip under WOT.

Didn't know if there were a lot of 6MT owners out there with significant miles on the JB4 yet?

Thanks!
