An instructional video on how to replace the automatic transmission fluid, filter and pan gasket on a Toyota Camry with a V6 engine.
Procedure is similar to many other cars that use a transmission filter (and not just a screen).
The fluid is drained via 10mm hex bolt, then 17 10mm bolts are removed to drop the pan. The filter is held in by 3 10mm bolts.
Keep the work area clean, as this can quickly become a messy job. A drain and fill of the transmission fluid will replace 1/3rd of the transmission fluid, as the rest is inside the torque converter. Frequent drain and fills over a period of time are recommended to keep the transmission oil fresh and clean. A fluid flush through the cooler lines is not recommended for older vehicles, due to the possibility of clogging a passage with debris.
The fluid was brown after an unknown amount of miles, and the filter had some small particles on its screen. The magnets were full of a magnetic sludge.
Once everything was cleaned it was reinstalled to 69in-lb of torque, and the drain bolt to 36 lb-ft of torque.
The transmission was refilled with Castrol Domestic ATF, which is Dextron III compatible.
