To check fluid level on a automatic transmission equipped with a fluid level instead of a dipstick, a technician would use a/an

• A. Dipstick
• B. Scan tool
• C. Hydrometer
• D. Multimeter

Answer: (B)

In this situation the level is read electronically through the vehicle’s transmission sensor system, so a diagnostic scan tool is used to access the transmission control module and display the fluid level. Modern automatics with an electronic level indicator rely on sensors and ECU data rather than a physical dipstick, and the scan tool communicates with that system to show whether the fluid is at the correct level for the current temperature and operating state. A dipstick wouldn’t be used because there’s no traditional dipstick to pull; a hydrometer measures fluid density, not how much fluid is in the transmission; and a multimeter only measures electrical properties, not fluid levels.
