Check Fluid Level and Condition

WARNING: This page is about a different car, the 2009 Ford Mustang. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION: The vehicle should not be driven if the fluid level is low or damage may occur.
CAUTION: Excessive temperatures may break down the transmission lubricant. If there is reason to believe that the transmission has been subjected to temperatures exceeding 135°C (275°F), change the lubricant immediately.

An incorrect level may affect the transmission operation and can result in transmission damage. To correctly check and add fluid to the transmission, refer to SPECIFICATIONS .

A low fluid level can result in poor transmission shifting, engagement or damage. It can also indicate a leak in one of the transmission seals or gaskets.

  1. Check the fluid condition.
    • Observe the color and the odor of the fluid. Allow the fluid to drip onto a white cloth and examine the stain. Check the fluid for contamination or metal particles.
      • Fluid should appear reddish in color.
