need to replace clutch cylinder, but caint get transmission out

Master or slave? Clutch cylinder removal doesn't require transmission removal.

then were is it located and how do u replace it

Master cylinder is located by the clutch pedal. Slave cylinder is on the side of the transmission. Look for the opening in the front of the transmission that should (hopefully) be covered with a rubber boot and has metal arm coming out of it. This is the clutch fork. There is a rod or bar on that fork. Follow it to the slave cylinder. There is a metal fluid line going to the clutch slave cylinder.
