Q: What does code P1733 mean?

3-4 Shift Malfunction. P1733 on a Ford vehicle means the powertrain control module (PCM) commanded a 3-4 upshift and the transmission did not achieve the expected gear ratio within its calibrated time window. The PCM monitors input shaft speed versus output shaft speed during the shift and flags this code when the calculated slip or ratio error exceeds the threshold for that shift.
