Final answer:
To check the fluid level in a vehicle transmission/transaxle without a dipstick, you would remove a plug. This plug allows you to access the transmission fluid for the purpose of checking or adding fluid, with the correct fluid level typically at the bottom edge of the fill plug hole.
Step-by-step explanation:
When a vehicle transmission/transaxle does not have a dipstick to check the fluid level, a plug would typically be removed to check or fill the transmission fluid. Unlike a dipstick, where you can directly measure the level, sealed transmission systems often have a specific fill plug that must be accessed to assess the fluid level or to add more fluid. The correct fluid level is usually at the bottom edge of the fill plug hole, and in some cases, a special procedure may be required to accurately check the fluid level, which often includes running the vehicle until it reaches operating temperature.
