Does it move when you put it into 1 on the selector?

Possible problems:

Seals or piston damaged
Clutch worn, missing, misassembled or damaged
Check ball not seating
Cylinder assembly outer diameter/case bore damaged, leaking



Would help if you can get codes pulled too. There more then likely is codes stored in it if it's slipping.

Take pan off check the check ball make sure its not plugged.. if it's not that then i think your into a transmission..
the piston can be removed from the side cap and inspected. if the break band is burnt then your screwed.
