To ensure there is sufficient transmission fluid to run the vehicle, at what temperature range should the fluid be when checking the level?

• A. 60°F to 120°F
• B. -25°F to 25°F
• C. 160°F to 200°F
• D. -22°F

Answer: (A)

Temperature affects how much transmission fluid appears on the dipstick. ATF expands when it gets hot and contracts when it’s cold, so the level reading depends on the fluid’s temperature. The marks on the dipstick are calibrated for a specific temperature window, and readings taken within that window are the most reliable indicators of how much fluid is actually in the system. Choosing a range of 60°F to 120°F means the fluid is warm enough to flow properly but not overheated, which would push the level higher due to expansion and potentially hide a low condition. Reading within this moderate temperature range gives an accurate picture of whether there is sufficient fluid to run the vehicle. If you check colder or hotter than this window, the reading can be misleading.
