Second gear can be declared stuck after repeated neutral requests

Third-gear disengagement uses a different fork-feedback branch

Fourth-gear stuck diagnosis follows the shift toward neutral

a CVT ratio fails despite reaching control limits

First-gear ratio checks require a stable commanded gear

Second-gear ratio errors need timing and repeat-count context

Third-gear ratio disagreement is a comparison, not a component verdict

Fourth-gear ratio verification must include the end of the shift

Fifth-gear ratio evidence must be separated from engagement evidence

Reverse needs its own diagnostic scope rather than a forward-gear threshold
