Useful checks before replacing parts
- Compare pressure sensor D readings with commanded pressure, gear state, fluid temperature, slip, and shift events under load.
- Inspect the sensor, internal harness, valve-body pressure source, connector condition, and shared reference or ground circuits.
- Check whether the performance fault follows one gear, one shift, hot operation, or pressure-control command changes.
