My clutch works perfectly normal until i am on an uphill incline and push the clutch in. At that time there is no pressure about 3/4 of the way down. It gets stiff at the bottom 1/4 which is just enough to release the clutch. I started noticing this when i would go up an incline so i could back up to turn around. So i go up incline and go to push the clutch in and it almost goes to the floor before there is any pressure and it will swing back and forth like its just hanging there. I go in reverse get back to where the jeep level and the clutch is back to normal. Fluid is fine and it has a new slave cylinder.
