My 86 RX7 Na, sometimes when I shift (its not gear specfic) I press down on the clutch and it won't shift. I raise my foot off the clutch and push again it shift's. What could be causing this problem? Clutch master and slave replaced 9 mos ago with aftermaket parts. Shifter bushing replaced over a year ago with oem parts.

 

Wrong section, but most likely the pilot bearing

 

lol... wrong section indeed...

i agree with post above... pilot bearing.
