How do you check fluid level on a 2000 ford mustang transmission that has no dip stick?

To check the fluid level on a 2000 Ford Mustang transmission without a dipstick, first, ensure the vehicle is on a level surface and the engine is warmed up. Locate the Transmission Fluid filler plug on the side of the transmission; it typically requires a 3/8-inch drive ratchet to remove. With the engine running, remove the plug; the fluid should be at the bottom of the opening. If fluid drips out, the level is adequate; if not, you'll need to add transmission fluid until it begins to seep from the hole.
