Symptoms of P0933
- 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 P0933
- 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
- Compare pressure sensor readings with pump command, pressure unit cycling, shift events, fluid temperature, and actual pressure if available.
- Inspect sensor reference and ground stability, connector condition, fluid condition, hydraulic restrictions, and pressure-control behavior.
- Check whether the fault appears during pressure build, engagement, hot operation, or rapid actuator movement.
