My clutch started slipping 42k on it 32k making lots of tq on is20 swap 357wtq to be exact. Lot of brake boosting, racing agressive driving. I’m going southbend stg 3 daily kit. Sucks your trans is having issues. Synco failure seems like issue from hard shifting and stuff from track events, if you have those bits floating around in there, that could of easily scartched a seal and caused it to pour. Hopefully its just a seal. But i’ll update when I do clutch kit. 700$ for soutbend kit with all new hardware throwout bearing, clutch disc, pressure plate, and 19 lb steel flywheel seem like a pretty good price.
