Have a 2004 RX8 . i rencently started having trouble shifting the gears. It seemed like they were getting very hard . realized a had a little leak going on on the " Master Clutch" so i replaced it and it got a little soft for about a day and then they started getting hard again. Now I have to turn car off to put in first gear and then when i try to start the car it seems like it wants to take off with the clutch pressed all the way down. Any suggestions on what this could be. I recently changed my clutch and pressure plate about 2 months ago, this problem started about 2 weeks ago.

 

Have you bled your Clutch Hydraulics?, at the Slave Cylinder bleeder nipple?, next or close to your OE Oil Filter location...

Could also be the Slave Cylinder itself needing renewal.

 

^^^ What he said, and check your clutch pedal while you're at it.

 

Yeah clutch pedal broke bout 1 month ago. Removed it and welded it and reinstalled it. Seems to be working good.
