Do you have to push in the clutch for it to go into gear or does it grind if the clutch is out and you try to put it in gear? <--- if you don't have to push in pedal then clutch / pressure plate is bad and the clutch isnt engaging with flywheel.
Can you start the car in gear with the clutch pedal up and does it jerk while trying to start? <--- if it doesn't jerk then clutch disk / pressure plate it bad and the clutch is not disengaging from flywheel, but doesnt seem to be your problem
If it jerks and starts then try and push in clutch and shift. <--- if you can't shift then clutch / pressure plate is bad. Again flywheel isn't disengaging from clutch disk.
Is there any clutch pedal? <--- if you can't feel any resistance then clutch / pressure plate problems
Can you put the car in gear and then try to push it with engine off? <---- if it moves then clutch isn't engaging
Try those in every gear to make sure the gears in tranny aren't stripped out.
It sounds to me like you did something with the clutch or pressure plate and the disc isn't engaging the flywheel for some reason. If no liquid is pouring out then you shouldn't have a problem with internal transmission work.
If you pull the tranny and the clutch / pressure plate are OK then you may have busted the tranny internals and might want to crack it open and check it out.
