Question

Quizplus · Accepted Answer

The correct procedure for checking the automatic transmission fluid (ATF) level in most vehicles is when the transmission is at operating temperature and the engine is running. This ensures accurate measurement since the fluid expands when warm and the pump, which operates only when the engine is running, affects the fluid level in the transmission.
