What does code P2786 mean?

Q: What does code P2786 mean?

Gear Shift Actuator Temperature Too High. P2786 means the transmission control module has detected that the gear shift actuator has exceeded its safe operating temperature, typically due to excessive current draw or mechanical binding. The computer sets this code when the actuator's internal temperature sensor or a calculated thermal model reports an over-temperature condition, often after repeated or prolonged shift attempts.
