Nissan Navara D40 Automatic Transmission Fluid Change

Need to change the automatic transmission oil in your Nissan Navara D40? Follow this easy guide to ensure proper maintenance and performance.

Regular maintenance of your Nissan Navara D40 automatic transmission is essential to ensure smooth and efficient operation. One crucial aspect of this maintenance is changing the Automatic Transmission Fluid (ATF) at recommended intervals. In this article, we will walk you through a step-by-step procedure on how to change ATF, highlighting the precautions you should take and the benefits of using Genuine Nissan ATF Matic Fluid J.

Why Change Automatic Transmission Oil?

The ATF in your Nissan Navara serves multiple purposes, including lubricating moving parts, providing hydraulic pressure, and dissipating heat generated during operation. Over time, the ATF can degrade, leading to diminished performance and potential damage to the transmission. Regularly changing the ATF helps maintain the transmission's optimal function, prolonging its lifespan and ensuring smooth gear shifts.

Preparation and Safety

Before you begin, gather the necessary tools and materials:

• Genuine Nissan ATF Matic Fluid J (Fluid Capacity: 10.3 liters)
• Drain pan
• Wrench or socket set
• Torque wrench

Safety Precautions:

Preparation and Safety

• Always perform ATF changes on a level surface.
• Ensure the vehicle is safely parked with the engine turned off.
• Use caution when working with hot ATF to avoid burns.
• Follow the manufacturer's guidelines and use only the recommended ATF to prevent damage to the transmission.

Step-by-Step Procedure in Changing A/T Fluid

Step-1. Warm Up ATF. Start the vehicle and let it run for approximately 10 minutes to warm up the ATF. Warm ATF flows more easily, facilitating its complete drainage.

Step-2. Stop the Engine. Once the ATF is warmed up, park the vehicle on a level surface and turn off the engine.

Step-3. Loosen the Level Gauge Bolt. Locate the A/T fluid level gauge bolt and use a wrench or socket set to loosen it.

Step-4. Remove the A/T Fluid Level Gauge. Gently remove the A/T fluid level gauge from its position. Take care not to damage the gauge during removal.

Step-5. Drain the Old ATF. Position a drain pan beneath the vehicle to catch the draining ATF. Remove the drain plug located at the oil pan to drain the old ATF completely.

Step-6. Replace the Drain Plug Gasket. Before reinstalling the drain plug, replace the gasket with a new one. Never reuse the old gasket as it may lead to leaks.

Step-7. Install the Drain Plug. Insert the drain plug back into the oil pan and tighten it to the specified torque using a torque wrench. Drain Plug Tightening Torque: 34 N-m (0.81 kg-m, 70 ft-Ib).

Step-8. Refill with New ATF. Refill the transmission with Genuine Nissan ATF Matic Fluid J through the A/T fluid charging pipe. Keep the engine idling during this process.

The amount of new ATF to use should be 30 to 50% increase in the specified amount. Use Genuine Nissan ATF Matic J for automatic transmission, the ATF capacity is 10.3 liter (9-1/8 imp qt).
