Useful checks before replacing parts
- Compare commanded pressure build, actual pressure data, pump operation, relay command, cycling interval, and hydraulic temperature.
- Inspect fluid level, leaks, accumulator function, pressure unit seals, pump output, pressure sensor plausibility, and related actuator faults.
- Identify whether pressure loss occurs during engagement, repeated shifts, hot operation, or after sitting.
