RepairPal Certified shops can diagnose and repair your 1997 Saturn SW1. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
P0733 indicates that the computer has detected and incorrect 3rd gear ratio. If you have that code than you have an internal transmission problem. It sounds like the shifting is faulty so I'm not surprised by the code. You could get it checked out by a transmission shop.
