4R100 Automatic Transmission

Fluid Capacity





1 Actual quantities will vary a few ounces based on applications. Always use the fluid level indicator for setting the correct level.

Caution: Using a transmission fluid that indicates a dual usage MERCON and MERCON V in a transmission application requiring MERCON may cause transmission damage. Use of any fluid other than the recommended fluid may cause transmission damage.

MERCON ATF is being replaced by MERCON V ATF as a service fluid, per TSB 06-14-4..

Note:Refer to the transmission fluid level indicator and the owners Guide for the type of transmission fluid required. Some fluid labels may indicate dual usage such as MERCON and MERCON V. These dual-usage fluids are not to be in transmissions that use only the MERCON type fluid. These dual-usage fluids may be used in transmissions that require MERCON V use.

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

The above fluid capacities are approximate dry fill capacity and include fluid coolers and fluid cooler tubes.Fluid level indicators 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 (48,000 km). A new inline transmission fluid filter should also be installed during any overhaul,exchanges or when internal contamination is present. If the vehicle is equipped with an inline transmission fluid filter,the filter only needs to be installed. If the vehicle is not one equipped with an inline transmission fluid filter, a new transmission fluid filter kit must be installed.
