🔧 QX60 - CVT Transmission Fluid Drain & Refill

This service replaces a portion of the CVT fluid by draining the pan and refilling with the correct fluid, then setting the level at the correct temperature. It helps protect the CVT from wear, overheating, and shudder.

Difficulty Level: Intermediate | Estimated Time: 1.5-3 hours

Assumption: Your QX60 uses Nissan/INFINITI NS-3 CVT fluid and the factory level-check method (temperature-based overflow/level plug).

⚠️ Safety & Precautions

• ⚠️ Work on level ground and support the vehicle on jack stands before going underneath.
• ⚠️ CVT fluid can be hot; let the drivetrain cool and wear gloves and safety glasses.
• ⚠️ Keep the engine running only when instructed; stay clear of belts/fans and moving parts.
• ⚠️ Use ONLY NS-3 CVT fluid; the wrong fluid can damage the CVT.
• ⚠️ Do not rely on a jack alone; always use jack stands.

📋 Before You Begin

• Park on a level surface, set the parking brake, and place wheel chocks behind the rear wheels.
• Gather a drain pan and enough NS-3 CVT fluid before opening anything.
• Have a way to read CVT fluid temperature using a scan tool (a scan tool is a plug-in device that reads live data from the vehicle computer).
• If your QX60 has been driving, let it cool so the fluid is warm, not scorching hot.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Raise and support the QX60

• Use a floor jack (rated 3-ton minimum) to lift the front of the vehicle at the approved front lift point.
• Set it down on jack stands (rated 3-ton minimum) and gently shake the vehicle to confirm it’s stable.
• Keep the vehicle as level as possible (level matters for fluid level checking).

Step 2: Remove the lower splash shield

• Use a trim clip remover and flathead screwdriver to remove plastic clips.
• Use your socket set (8mm-19mm) and 3/8" drive ratchet to remove any small bolts holding the shield.
• Set the shield and fasteners aside in a tray.

Step 3: Locate the CVT drain plug and fill plug

• Place a drain pan (10-quart minimum) under the CVT.
• Identify the fill plug first (important: you want to know you can refill before you drain).
• Clean around both plugs using shop rags and brake cleaner spray.

Step 4: Drain the CVT fluid

• Use a socket set (8mm-19mm) and 3/8" drive ratchet to remove the CVT drain plug.
• Let fluid drain until it becomes a slow drip (this may take 10-20 minutes).
• Remove and replace the drain plug crush washer with the new one.

Step 5: Reinstall the drain plug

• Thread the drain plug in by hand first to avoid cross-threading.
• Use a torque wrench (10-100 Nm range) to tighten the drain plug: Torque to 34 Nm (25 ft-lbs).
• Hand-thread first; cross-threads are expensive.

Step 6: Refill with NS-3 CVT fluid

• Remove the CVT fill plug using your socket set (8mm-19mm) and 3/8" drive ratchet.
• Install a new fill plug crush washer on the fill plug.
• Use a fluid transfer pump (specialty) to pump in NS-3 CVT fluid.
• Add approximately the same amount you drained (typical drain-and-fill is about 4-6 quarts, but measure what came out).

Step 7: Circulate fluid and bring it to the level-check temperature

• With the vehicle still safely on jack stands, start the engine and keep your foot on the brake.
• Move the shifter slowly through P-R-N-D and back to P, pausing 3 seconds in each position.
• Connect your scan tool with CVT fluid temp data (specialty) and monitor CVT fluid temperature.
• Bring the CVT fluid to the level-check range: 35°C-45°C (95°F-113°F).

Step 8: Set the CVT fluid level (overflow/level method)

• With the engine idling and CVT temp in range, remove the CVT level/overflow plug (if equipped) using your socket set (8mm-19mm) and 3/8" drive ratchet.
• If fluid does not dribble out, use the fluid transfer pump (specialty) to add NS-3 until it just begins to flow/dribble.
• Let it dribble until it becomes a thin stream/drip, then reinstall the level/overflow plug.
• Use a torque wrench (10-100 Nm range) to tighten plugs to factory specification.

Step 9: Reinstall the splash shield

• Reinstall the shield using your socket set (8mm-19mm), 3/8" drive ratchet, and any lower engine splash shield clips needed.
• Make sure no shield edges touch the exhaust or spinning parts.

Step 10: Lower the vehicle

• Use the floor jack (rated 3-ton minimum) to lift slightly, remove jack stands, and lower the vehicle.
• Wipe any spilled fluid using shop rags and brake cleaner spray.

✅ After Repair

• Start the engine and check underneath for leaks around the drain/fill/level plugs.
• Test drive 10-15 minutes with gentle acceleration; confirm no shudder, flare, or warning lights.
• Recheck for leaks after the drive.
• If you have a scan tool, check for stored CVT-related codes and clear only if appropriate.
• Dispose of used fluid at a recycling center.
