How to check transmission fluid level 2013 Ford Mustang V6

If the installation of a new transmission fluid cooler or transmission fluid cooler tubes has been carried out, the vehicle must be driven to get the transmission fluid to a temperature of 88°C (190°F) in order to purge the air from the transmission fluid cooling system.

1. With the engine running, place the transmission selector lever in each gear position and hold approximately 5 seconds. Place the transmission selector lever in PARK.
2. With the engine idling (600-750 rpm) in PARK, position it on a hoist.
3. Remove the transmission fluid fill plug and transmission fluid level indicator assembly, located on the passenger side front portion of the transmission case.

4. Separate the transmission fluid level indicator from the transmission fluid fill plug.

5. Wipe the transmission fluid level indicator clean. Reinstall only the transmission fluid level indicator back into the transmission fluid fill plug hole to check the transmission fluid level.

6. The transmission fluid level indicator has 2 areas for the fluid level, a crosshatched (labeled A) area and a dotted (labeled B) area. Use the crosshatched area when checking the transmission fluid level. The correct transmission fluid level is at the upper level of the crosshatch marks on the transmission fluid level indicator.

Using the scan tool, verify that the Transmission Fluid Temperature (TFT) is between 80°C-85°C (176°F-185°F). Do not overfill the transmission. The transmission fluid level must be at the upper level of the crosshatch mark.

7. If the transmission fluid is not at the correct level, follow the steps for Adding Additional Transmission Fluid or Removing Transmission Fluid. Install the transmission fluid fill plug.
