i just rebuilt my trans and i put MT-90 in it, shifting was amazing, smooth as butter, then all of the sudden shifting gets really hard, sometimes doesnt want to go into gear unless i pump the clutch a bit, even still its still stiff. So i pop the hood and was low on clutch fluid and i also saw the hard clutch line from the trans to the slave cylinder was leaking, so i tightened it up and it stopped leaking, re-bled the clutch system. worked fine smooth again. Now all of the sudden its hard again, no fluid leaks. I re-bleed it and it was smooth for about 10 mins, wtf is going on ?? ? ? this is getting annoying.
i have new slave cylinder, clutch master cylinder, Good ridge braided clutch line, clutch, fulcrum ball & clutch fork.
