Installation (Setup)

Installation of a transmission filter requires specific tools and knowledge of automotive systems. If you are not experienced with automotive repair, it is highly recommended to seek professional assistance.

General Installation Steps (Consult Vehicle Service Manual for specifics):

1. Safety First: Ensure the vehicle is safely lifted and supported on jack stands. Allow the transmission to cool to prevent burns from hot fluid.
2. Drain Fluid: Place a drain pan under the transmission. Carefully loosen and remove the transmission pan bolts, starting from one end and working your way around, leaving a few bolts on one side to allow the pan to tilt and drain gradually.
3. Remove Pan: Once most of the fluid has drained, remove the remaining bolts and carefully lower the transmission pan. Be prepared for additional fluid spillage.
4. Remove Old Filter: Locate and remove the old transmission filter. This usually involves pulling it down or removing a few retaining bolts. Note its orientation.
5. Clean Pan: Thoroughly clean the transmission pan, removing all old gasket material and any metal shavings or debris. Clean the pan magnet if present.
6. Install New Filter: Install the new Purolator P1240 filter in the same orientation as the old one. Ensure it is securely seated.
7. Install New Gasket: Place the new gasket onto the clean transmission pan.
8. Reinstall Pan: Carefully lift the pan with the new gasket into place and start threading the pan bolts by hand. Tighten the bolts evenly in a crisscross pattern to the torque specifications provided in your vehicle's service manual. Overtightening can damage the gasket or pan.
9. Refill Fluid: Lower the vehicle. Refill the transmission with the correct type and amount of transmission fluid specified by your vehicle manufacturer. Check the fluid level according to the vehicle's service manual (usually with the engine running and transmission warm).
10. Check for Leaks: Start the engine, shift through all gears, and then recheck the fluid level and inspect for any leaks around the pan.

Function (Operating)

The Purolator P1240 Transmission Filter functions by filtering the transmission fluid as it circulates through the automatic transmission system. Its primary role is to remove contaminants such as metal wear particles, clutch material debris, and other impurities that can accumulate over time. By maintaining clean fluid, the filter helps to:

• Prevent wear on internal transmission components.
• Ensure proper hydraulic pressure and smooth gear changes.
• Extend the overall lifespan of the transmission.

The filter operates continuously whenever the transmission fluid is circulating.

Maintenance

Regular maintenance of your transmission filter is critical for vehicle longevity. Purolator recommends changing your transmission fluid and filter every two years or 24,000 miles, or as specified in your vehicle's owner's manual. Factors such as heavy towing, frequent stop-and-go driving, or extreme temperatures may necessitate more frequent changes.

Always use the correct type of transmission fluid recommended by your vehicle manufacturer when performing a fluid and filter change.

Troubleshooting

A properly functioning transmission filter is essential. If you experience any of the following symptoms, it may indicate an issue with your transmission filter or fluid, and professional inspection is recommended:

• Delayed or Rough Shifting: Transmission takes longer to engage gears or shifts harshly.
• Slipping Gears: Engine RPM increases without a corresponding increase in vehicle speed.
• Unusual Noises: Whining, clunking, or humming sounds from the transmission.
• Overheating Transmission: Indicated by a warning light or a burning smell.
• Contaminated Fluid: Transmission fluid appears dark, cloudy, or has a burnt smell.

These symptoms can also indicate other transmission problems, so a thorough diagnosis by a qualified mechanic is advised.
