I just replaced the clutch and the slave cylinder. Bled the slave cylinder and the vehicle will not slip in to gear when clutch is applied. Will start in gear but moves forward with clutch applied and pressing on the brakes while turning it over. Could this transmission or clutch problems? If anyone can help that would be great! If this is not enough information please feel free to tell me.

Did you purge all air from the hydraulic clutch system? It sounds like the clutch is not retracting enough to shift gears, which may be a function of air in the system.
