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 continue driving aggressively with multiple-gears-engaged behavior; it can cause severe transmission damage.

Useful checks before replacing parts

Review commanded gear, actual ratio, input speed, output speed, solenoid states, and pressure-control data at the fault event.
Check fluid condition, valve-body sticking, solenoid command, clutch apply logic, and companion ratio or solenoid codes.
Identify whether the condition is electrical command related, hydraulic cross-leak related, or mechanical clutch related.
