It can't be done on the Mitsu automatic.(jump start) As Dan said you need a "rear pump" and what that is is a hydraulic pump that is driven by the rear driveshaft. Early dodge/chrysler automatics had them, along with Several models of Mercedes and the Porsche 928 automatics. That is all of the automatics that actually came with a rear pump to my experience.
