Symptoms of P0796
- 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 P0796
- 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 commanded pressure, actual pressure if available, slip, shift timing, and solenoid C duty cycle during the fault.
- Inspect fluid level and condition, valve-body sticking, solenoid operation, internal harness, and pressure-related companion codes.
- Determine whether the concern is harsh engagement, flare, delayed shift, limp mode, or pressure remaining too low.
