MERCON(R) automatic Transmission Fluid is being replaced by MERCON(R) V as a service fluid, as per TSB 06-14-4.

NOTE: Always use the fluid level indicator to check and set the correct level of transmission fluid.

The above fluid capacities are approximate dry fill capacity and include fluid coolers and fluid cooler tubes. The fluid level indicator should be used to determine actual fluid requirement and fluid specifications. Check level at operating temperature. DO NOT OVERFILL.
The transmission fluid should be changed every 30,000 miles (48,000 km) regardless of normal or special operating conditions.
Once the vehicle is equipped with the inline transmission fluid filter, a new filter should be installed every 30,000 miles (48,000 km). A new inline transmission fluid filter should also be installed during any transmission overhaul, exchange, repair or if internal contamination is present. If the vehicle is equipped with an inline transmission fluid filter a new filter only needs to be installed. If the vehicle is not equipped with an inline transmission fluid filter, a new inline transmission fluid filter kit should be installed.
