Useful checks before replacing parts
- Compare commanded pressure, actual pressure if available, pressure-control solenoid command, slip, gear ratio, and fluid temperature.
- Inspect fluid level and condition, filter restriction, pump operation, valve-body function, pressure sensor data, and related solenoid codes.
- Identify whether symptoms are harsh shifts, delayed engagement, flare, limp mode, or pressure faults only under load.
