Instructions for changing the oil in a Mazda 3 automatic transmission:
1. Prepare the vehicle: Place the vehicle on a level surface and apply the parking brake. Allow the engine to cool.
2. Locate the drain plug: Look under the vehicle and locate the drain plug on the bottom of the transmission.
3. Drain the old oil: Place a container under the drain plug. Carefully unscrew the plug by hand or with a key. Allow the old oil to drain completely.
4. Remove the transmission pan: Place a shallow container under the transmission. Unscrew the bolts securing the pan and carefully remove it from the transmission housing. Residual oil may leak out.
5. Replace the gasket: Remove the old gasket from the pan and replace it with a new one.

7. Replace Transmission Filter (Optional): If your Mazda 3 is equipped with an external transmission filter, replace it with a new one.
8. Reinstall the pan: Apply sealant to the new gasket and reinstall the pan. Tighten the bolts in the order specified in the repair manual.
9. Install the drain plug: Replace the O-ring on the drain plug and screw the plug into place.
10. Fill with new oil: Using a funnel, fill the transmission with the required volume of new ATF. Check the fluid level using the dipstick or level indicator, if equipped.
11. Check the fluid level: Start the engine and let it idle. Move the gear selector to all positions, then return it to the park position. Check the fluid level using a dipstick or level indicator. Add liquid if necessary.
12. Reset the service counter: If your Mazda 3 is equipped with an electronically controlled automatic transmission system, you may need to reset the service counter according to the instructions in your repair manual.
