2000 Isuzu Rodeo clutch problem

First I was experiencing the pedal having way to much play and after bleeding the slave cylinder the problem would come back the next day. I have replaced the slave cylinder and bled it, everything is great. Great pressure in the pedal. Now the problem is that when I am in gear and stepping on the gas the engines RPM's rev high as it is excelerating. If I am acting as a sunday driver everything is good. Prior to the replacement if I was in the wrong gear it would just creep up in speed, now it rev's high as it creeps. Even if I am in the right gear and stepping on the gas for a quick acceleration it the rpm's race as the engine gets to the speed I need. Is there something I need to adjust?
