P1751 on Honda

Transmission code whose meaning differs: a hydraulic malfunction on Honda and Acura, a control relay fault on Mitsubishi

Severity: Severity not verified — if the car runs badly, have it inspected

The two meanings differ by make and the reports we read describe shifting trouble and an intermittent no-start, with no source that sets a safe driving limit.

It gets more serious if:

  • Inspect soon: The transmission shifts harshly, slips, shows warning lights or the vehicle intermittently will not start.
