I have a 98 jdm itr tranny with problems on 4th gear. At high speed it wont shift (sometimes it does) It all started one day...after making my LS >VTEC i started having problems with 3th gear not shifting at hifh speed (8800 - 9400rpms).
Some days later i found the slave cylinder haging by just one bolt! so we figure out it was that the problem...
It worked fine... and after another day at the track it started randomly doin it.
But it worked, now i made my car b20-vtec (216whp) and it started again worst.
It doesnt make any noise, no grinding, it feels just like when the slave cylinder was not applying whole pressure, since it was hagingg w just one bolt. I use ACT street Presure plate w/ exedy OEM disc.
We replaced whole clutch master cylinder + slave, new fluid, OEM tranny oil, act flywheel, etc...
i daily drive the car, It works fine; it just doesnt shift after around 8500rpm

ANY HELP??? Someone with same problem...
