A leaking cylinder will definetly cause a problem. You should notice the problem more in 1st or revese. Be sure the trans is full of the CORRECT fluid. 2nd gear should offer no problems at all once the vehicle is moving. Is the problem going into 2nd when you are shifting from 1st. or are you taking off in 2nd? That trans can be easily shifted without the use of the clutch once the vehicle is moving if you time the speed and rpm's if you know how. If it gives problems with or without the clutch you might have internal trans problems.
