Useful checks before replacing parts
- Check pressure sensor D signal voltage, reference voltage, ground, connector condition, and continuity through the transmission case connector.
- Compare sensor D data with commanded gear, pressure-control commands, shift timing, slip, and fluid temperature.
- Inspect internal harness routing, fluid contamination at terminals, sensor mounting, and companion pressure or ratio codes.
