I have a 2003 mazda 6. Had to replace the transmission and clutch. I installed the new clutch and the transmission. When i had the car on jackstands i cranked it up. The car was in nuetrual and both wheels where turning. I tried to put it in gear. It wouldnt go into gear. When the car was off i put it into gear and the qheels still turned freely. I pushed the clutch pedal and can see the slave cylinder engage the fork. The wheels keep turning though. If i apply the brakes the car doesnt die. Any ideas. I jeep seeing that i might have put the disk in backwards. Any help would be appreciated. Im in the processes of pulling the transmission out again.
