yes, go to a dealer and trade for either a 350 rancher or 500 foreman.
seriously, if by manual transmission you mean a 5 speed gearbox, then the answer is no. the AT has sensors and an ECM to tell the tranny when to shift that would not be needed on a manual tranny machine. even if you installed a 350 rancher motor in the frame, the wire harness and electronics would all have to be changed to work w/ the different tranny.
