Useful checks before replacing parts
- Compare shift solenoid A command, circuit feedback, current draw if available, actual gear ratio, shift timing, and fluid temperature.
- Inspect solenoid A wiring, case connector terminals, internal harness condition, valve-body connector fit, and voltage drop under load.
- Check whether the range/performance fault follows one shift, hot operation, low system voltage, or a related pressure-control issue.
