Slave cylinder question
 

Im having troubles putting my car into gear when the engine is on. However it shifts perfectly when the engine is off. My clutch pedal doesn't come back up when i press it in. Check all lines for leak and couldn't find any leaks. I went under my car and had someone press the clutch pedal for me and it looks like the slave cylinder is pushing out. My question is how far is the slave cylinder rod suppose to push out? Another question is i took off the slave cylinder, and the rod wiggles from side to side like a ball joint. Is it suppose to be like that? Already bled the lines and no bubbles. Fluid color looks gold. Car is 04 grand touring edition. Any ideas? Ohh yeah this all happened after i did a transmission+gear oil change. Don't know if that has anything to do with it.

Nothing?
