(always wear protective safety goggles and gloves before work begins)

Step 9 of 14. Changing Transmission Filter

Most automatic transmissions have a filter that is located in the transmission pan. Some filters are secured to the transmission with bolts or clips. The transmission filter in this photo is held in by a o-ring seal at the front of the filter. Grasp the transmission filter firmly and twist slightly to remove, fluid will be present in the filter.

Step 10 of 14. Identify Internal Transmission Parts

Before reinstalling transmission pan; clean the gasket sealing surface with a shop towel. This enables a secure seal to the new gasket when the pan is reinstalled. While the transmission pan is remove you can inspect the electrical connection to the shift control solenoids. The control solenoids determine what gear the transmission is operating in and are housed in the valve body. All electrical connectors inside the transmission should be secure for a good electrical connection.

Step 11 of 14. Re-install New Transmission Filter

Always replace the seal for the transmission filter. Like with most seals, it is important that this seal does not leak. If the transmission filter seal leaks it can cause the transmission to ingest air causing low transmission hydraulic pressure, allowing the clutch disc's to slip and cause premature failure. Re-install filter in it's proper location, re-bolt or re-clip as needed.

Step 12 of 14. Re-Install Pan

Carefully reinstall the transmission pan, do not damage the gasket on reassembly or transmission fluid could leak. Reinstall bolt and tighten them in sequence one away from the other and continue until all pan bolts are snug. (note: do not over tighten, pan gasket could flatten out and leak)
