Ford Mustang (2005-2014) Owners Manual: Transmission fluid check

Checking Automatic Transmission Fluid

Note: Transmission fluid should be checked and, if required, added by an authorized dealer.

The automatic transmission does not have a transmission fluid dipstick.

See your Scheduled Maintenance Information for scheduled intervals for fluid checks and changes. Your transmission does not consume fluid.

However, the fluid level should be checked if the transmission is not working properly, (i.e., if the transmission slips or shifts slowly) or if you notice some sign of fluid leakage.

Do not use supplemental transmission fluid additives, treatments or cleaning agents. The use of these materials may affect transmission operation and result in damage to internal transmission components.

Checking and Adding Manual Transmission Fluid (if equipped)

1. Clean the filler plug. It is located on the passenger side of the transmission.
2. Remove the filler plug and inspect the fluid level.
3. For vehicles equipped with a V6 engine, the correct manual transmission fill level is at the lower edge of the filler hole. For vehicles equipped with a V8 engine, the correct manual transmission fill level is 1/2 in (1.3 cm) below the edge of the filler hole.
4. Add enough fluid through the filler opening to bring the fluid up to the recommended levels.

5. Install and tighten the fill plug securely.
Use only fluid that meets Ford specifications. See the technical specifications chart in the Capacities and Specifications chapter.
