Diagnostic boundary
A diagnostic trouble code reports that a monitored test failed. It does not prove one specific part is bad, and manufacturer logic can add vehicle-specific conditions.
Do not replace hydraulic parts until the shift solenoid B circuit has been tested for opens, shorts, and connector problems.
Useful checks before replacing parts
- Check solenoid B power feed, control circuit, connector condition, internal harness, case connector, and terminal fit.
- Measure resistance or current using the transmission service procedure and compare with known-good circuits.
- Inspect for shared feed issues if multiple solenoid electrical codes are stored together.
