P0893 Multiple Gears Engaged

P0893 indicates multiple gears engaged. The transmission controller sees speed or hydraulic behavior suggesting more than one gear path is applied.

Code details

Generic OBD-II · P0

System: Transmission
Code type: Generic (SAE / ISO controlled)
Standard: SAE J2012 / ISO 15031-6

Diagnostic boundary

A diagnostic trouble code reports that a monitored test failed. It does not prove one specific part is bad, and manufacturer logic can add vehicle-specific conditions.

Do not continue driving aggressively with multiple-gears-engaged behavior; it can cause severe transmission damage.

Symptoms of P0893

Harsh, delayed, or slipping shifts, or being stuck in one gear.
Check-engine light, sometimes with limp-home mode.
Flaring RPM or a shudder under load.

Common causes of P0893

Low or degraded transmission fluid.
A failing speed sensor, shift solenoid, or pressure-control circuit.
Wiring, connector, or internal hydraulic/mechanical faults.

Useful checks before replacing parts

Review commanded gear, actual ratio, input speed, output speed, solenoid states, and pressure-control data at the fault event.
Check fluid condition, valve-body sticking, solenoid command, clutch apply logic, and companion ratio or solenoid codes.
Identify whether the condition is electrical command related, hydraulic cross-leak related, or mechanical clutch related.
