Pan to catch fluid

Steps:

**1. Diagnosis:

Identify the specific issue with the automatic transmission. Common problems include slipping, delayed or rough shifting, or unusual noises.

**2. Check Transmission Fluid:

Ensure the transmission fluid level is correct. Low or dirty fluid can lead to transmission issues. If necessary, perform a fluid flush and replace with the manufacturer-recommended fluid.

**3. Inspect for Leaks:

Check for any signs of transmission fluid leaks. Leaks can be a common cause of low fluid levels and subsequent transmission problems.

**4. Scan for Error Codes:

Use an OBD-II scanner to check for any error codes related to the transmission. This can provide additional insights into the specific problem.

**5. Drop the Transmission Pan:

Lift the vehicle using a jack and secure it with jack stands. Remove the transmission pan to access the transmission filter and fluid.

**6. Replace Filter and Gasket:

Replace the transmission filter and gasket. This is a crucial step to ensure proper fluid flow and filtration within the transmission.

**7. Inspect Solenoids and Sensors:

Inspect the transmission solenoids and sensors for any signs of wear or damage. These components play a key role in the transmission’s performance.

**8. Check Clutch Packs:

If your Nissan Patrol has a traditional automatic transmission with clutch packs, inspect them for wear. Worn clutch packs can lead to slipping.

**9. Torque Converter Inspection:

Check the torque converter for any issues. Problems with the torque converter can result in poor transmission performance.

**10. Reassembly:

Reinstall the transmission pan with a new gasket, ensuring proper torque specifications. Refill the transmission with the correct amount and type of fluid.

**11. Test Drive and Monitor:

Take the vehicle for a test drive to ensure the transmission shifts smoothly and operates correctly. Monitor for any abnormal behavior.

**12. Professional Assistance:

If the issue persists or if you’re uncertain about the repair process, seek professional assistance from a qualified mechanic or a Nissan service center.

Transmission repairs can be complex, and proper diagnosis is crucial. If you’re not experienced with transmission work, it’s advisable to consult a professional for accurate identification and resolution of the issue.
