🔧 Versa - CVT Transmission Fluid Drain & Refill

On your Versa’s CVT (continuously variable transmission), fresh fluid helps the belt/pulleys and internal pump stay protected and operate smoothly. This is typically a drain-and-refill service (not a “power flush”), then you set the fluid level at the correct temperature.

Difficulty Level: Intermediate | Estimated Time: 1.5-3.0 hours

Assumption: Your Versa uses Nissan CVT fluid NS-3 and has a drain plug on the CVT pan.

⚠️ Safety & Precautions

• ⚠️ Work on a flat, level surface; support the car with jack stands, not the jack.
• ⚠️ CVT fluid level is temperature-sensitive; checking it cold can cause over/under-fill.
• ⚠️ Wear nitrile gloves and safety glasses; CVT fluid is slippery and can irritate skin.
• ⚠️ Let the exhaust and transmission cool if recently driven to avoid burns.
• ⚠️ Do not “flush” a CVT with a machine unless Nissan specifies it; drain-and-refill is the safe DIY method.

📋 Before You Begin

• 🅿️ Park on level ground, set the parking brake, and place wheel chocks at the rear wheels.
• 📏 You must keep the car level while checking/finalizing fluid level; raise the front evenly and support with jack stands.
• 🌡️ Your OBD2 scan tool with live data reads transmission fluid temperature (TFT/CVT fluid temp) so you can set the level correctly.
• 🧼 Lay out rags and a drain pan; CVT fluid spreads fast if spilled.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Warm the CVT fluid slightly

• Start the engine and let it idle 3–5 minutes, then shut it off.
• This helps the fluid drain more completely without getting dangerously hot.

Step 2: Raise and support the car level

• Place wheel chocks behind the rear tires.
• Use a floor jack (rated 2-ton minimum) to lift the front at the center jacking point.
• Set the car onto jack stands (rated 2-ton minimum) at the pinch welds or approved stand points.
• Give the car a gentle shake to confirm it is stable before going underneath.

Step 3: Remove the lower splash shield (if equipped)

• Use a trim clip remover to pop out plastic clips.
• Use a 10mm socket with a 3/8" drive ratchet to remove bolts.
• Set clips/bolts aside in a tray so you don’t lose them.

Step 4: Locate the CVT drain plug and prepare to drain

• Place a drain pan (10-quart minimum) under the CVT pan drain plug.
• Wipe dirt around the plug using shop rags so debris doesn’t enter the transmission.

Step 5: Drain the old CVT fluid

• Use the correct-size socket (commonly 12mm socket) with a 3/8" drive ratchet to loosen and remove the drain plug.
• Let the fluid drain until it slows to a drip (usually 10–20 minutes).
• Clean the drain plug with shop rags and a light spray of brake cleaner spray.
• Install a new CVT drain plug crush washer onto the drain plug.

Step 6: Reinstall and torque the drain plug

• Thread the drain plug in by hand first to avoid cross-threading.
• Use a 3/8" drive torque wrench (10-80 Nm range) to tighten the drain plug: Torque to 34 Nm (25 ft-lbs).
• If it doesn’t thread smoothly, stop and realign.

Step 7: Add new CVT fluid

• Refill method depends on your Versa’s fill point:
• If you have a dipstick tube/fill tube on top: use a long funnel to add fluid.
• If you have a fill plug: use a fluid transfer pump (specialty) to pump fluid into the fill port.
• Add roughly the same amount you drained (typical drain/refill is about 3–4 quarts), then you will fine-tune the level in the next steps.

Step 8: Circulate fluid through all ranges

• Start the engine with the brake pedal held firmly.
• Slowly shift through P-R-N-D-L, pausing ~3 seconds in each position.
• Return to P and leave the engine idling.

Step 9: Set the final CVT fluid level at the correct temperature

• Connect your OBD2 scan tool with live data (specialty) and monitor CVT fluid temperature (often shown as TFT or CVT Fluid Temp).
• Target a warm check range: 35–45°C (95–113°F) with the engine idling and the car level.
• Choose the correct level-check method for your Versa:
• Method A (Dipstick-equipped): Pull the dipstick, wipe it with shop rags, reinsert fully, then read. Add small amounts using a long funnel until it reaches the correct “HOT” range at temperature.
• Method B (Overflow/level plug style): With engine idling at the target temperature, carefully remove the level/overflow plug using the appropriate socket (commonly 10mm socket or 12mm socket). Add fluid using the fluid transfer pump (specialty) until it just begins to trickle from the level port, then reinstall and tighten the plug securely using a 3/8" drive torque wrench if a spec is available.
• Go slowly—small top-offs make a big difference.

Step 10: Reinstall the splash shield and lower the car

• Reinstall the splash shield using the 10mm socket and trim clip remover (for clips).
• Use the floor jack (rated 2-ton minimum) to lift slightly, remove jack stands, then lower the car.

✅ After Repair

• 🧪 Test drive 10–15 minutes with gentle acceleration; confirm no slipping, shuddering, or delayed engagement.
• 🔍 Park on clean pavement and look underneath for any fresh leaks around the drain plug and undertray.
• 🌡️ Recheck level the same way you set it (at temperature, car level) if you notice any odd shifting behavior.
• 🧴 Dispose of used CVT fluid properly at a recycling center or auto parts store.
