Which option correctly identifies the three broad areas of transmission failures?

• A. Diagnostic
• B. Electronic
• C. Technical
• D. Chemical

Answer: (B)

The main idea here is that modern transmissions are heavily controlled by electronic systems. Faults in these systems—such as issues with the transmission control unit, wiring, sensors, solenoids, or actuators—constitute a broad area of transmission failures. When electronic controls aren’t communicating correctly or aren’t receiving accurate signals, shifts can become harsh, delayed, or fail to occur, even if the mechanical parts are sound. That makes the electronic category a distinct and common source of transmission problems in today’s vehicles. The other options don’t describe a area where failures occur. Diagnostic refers to the process used to find faults, not a type of failure itself. Technical is too vague to describe a failure domain, and chemical isn’t relevant to transmission fault categories.
