🔧 Malibu - Transmission Fluid Drain and Fill

This procedure replaces part of the automatic transmission fluid in your Malibu. The 6-speed transmission has no dipstick, so the final fluid level must be checked through the level plug while the engine is running and the fluid is within the specified temperature range.

Difficulty Level: Advanced | Estimated Time: 1.5-2.5 hours

Assumption: This procedure applies to the stock 6-speed automatic transmission fitted with the 1.5L turbo engine.

⚠️ Safety & Precautions

• ⚠️ The Malibu must remain level while raised. Never work beneath a vehicle supported only by a jack.
• ⚠️ The final level check is performed with the engine running. Keep hands, clothing, and tools away from moving and hot components.
• ⚠️ Transmission fluid near the checking temperature can cause burns. Wear gloves and safety glasses.
• ⚠️ Do not remove the level plug with the engine off during the final check. Excess fluid may escape and produce an incorrect level.
• ⚠️ Do not use universal ATF, CVT fluid, or DEXRON-HP fluid. This transmission requires licensed DEXRON-VI automatic transmission fluid.
• ⚠️ Do not perform a pressurized flush. A measured drain and fill is the safer DIY service.
• 🔋 Battery disconnection is not required.

🔩 Required Parts

HowToo sells all the parts you need for this repair:

• Licensed DEXRON-VI automatic transmission fluid - Qty: 6 quarts
• Transmission drain-plug sealing washer - Qty: 1
• Transmission level-plug sealing washer - Qty: 1

A normal drain usually removes approximately 4-5 quarts, but the measured amount can vary. The transmission filter is internal and is not replaced during a routine drain and fill.

📋 Before You Begin

• 🚗 Park your Malibu on firm, level ground. Apply the parking brake and chock the rear wheels.
• 🌡️ Begin with the transmission cool enough to handle safely. The final fluid-level check requires a scan tool that displays transmission fluid temperature, abbreviated TFT.
• 📏 Raise and support all four corners at equal height. Use a digital level on a flat body or underbody reference surface to verify the vehicle is level front-to-rear and side-to-side.
• 🧰 A fluid transfer pump moves fluid through a hose when normal funnel access is restricted.
• 📱 No infotainment service mode or battery registration is required.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Warm and circulate the old fluid

• Drive your Malibu gently for approximately 10 minutes, then park on the prepared level surface.
• Move the shifter through Reverse, Neutral, and Drive for about three seconds in each position. Return it to Park.
• Switch off the engine and allow hot exhaust parts to cool before working underneath.

Step 2: Raise and level the vehicle

• Use the hydraulic floor jack at the approved lifting points and place all four jack stands beneath the approved support points.
• Use the digital level to confirm the Malibu is level in both directions.
• Push the vehicle gently before going underneath. It must remain completely stable.
• Level support is essential for an accurate fill.

Step 3: Remove the lower splash shield if equipped

• Use the 10mm socket, extension, and 3/8-inch-drive ratchet to remove any fasteners blocking access to the transmission drain plug.
• Support the shield with one hand while removing its final fastener.
• Set the fasteners aside in their original positions.

Step 4: Verify the fill cap can be opened

• From above, locate the transmission-fluid fill cap on top of the transmission case beneath the hood.
• Clean around the cap with shop towels so dirt cannot fall inside.
• Loosen the cap by hand before draining the transmission. Do not continue if the cap cannot be opened.

Step 5: Drain the old transmission fluid

• Place the graduated drain pan directly beneath the transmission drain plug.
• Use the 11mm 6-point socket and 3/8-inch-drive ratchet to remove the drain plug carefully.
• Allow the fluid to drain until it slows to an occasional drip.
• Measure and record exactly how much fluid came out. Inspect it for metallic particles, heavy black debris, or a strong burned odor.
• A thin gray paste is less concerning than chips.

Step 6: Reinstall the drain plug

• Clean the drain plug with shop towels and install a new sealing washer.
• Thread the plug into the transmission by hand to avoid damaging the aluminum case.
• Use the 11mm socket and torque wrench to tighten the drain plug to 12 Nm (106 in-lbs).
• Do not overtighten the plug.

Step 7: Add the measured replacement fluid

• Remove the loosened fill cap by hand.
• Use the long-neck transmission funnel, or the fluid transfer pump if access is restricted, to add the same amount of new DEXRON-VI fluid that was drained.
• Pour slowly to prevent the fill opening from overflowing.
• Install the fill cap by hand until fully seated.

Step 8: Connect the scan tool

• Connect the automotive scan tool to the diagnostic connector below the driver-side dashboard.
• Select the transmission control module data and display Transmission Fluid Temperature.
• Keep the scan tool connected throughout the level-setting procedure.

Step 9: Circulate the new fluid

• Start the engine and keep your foot firmly on the brake pedal.
• Move the shifter through Reverse, Neutral, and Drive, pausing about three seconds in each position. Repeat once and return the shifter to Park.
• Leave the engine idling. Do not raise engine speed during the level check.
• Use the shop light to check the drain plug for leakage.

Step 10: Bring the fluid to checking temperature

• Watch transmission fluid temperature on the automotive scan tool.
• Allow the fluid to reach 85-95°C (185-203°F) while the engine idles.
• If the temperature exceeds the range before the level is corrected, install the level plug, switch off the engine, and let the transmission cool before trying again.

Step 11: Set the transmission-fluid level

• Keep the engine running, the shifter in Park, and the Malibu level on all four jack stands.
• Place the graduated drain pan beneath the transmission level plug on the transmission case.
• Use the 11mm socket, extension, and 3/8-inch-drive ratchet to remove the level plug carefully.
• If fluid runs out in a steady stream, allow it to drain until it becomes a thin trickle or slow drip.
• If no fluid comes out, use the long-neck funnel or fluid transfer pump to add DEXRON-VI through the upper fill opening in small amounts until fluid begins to trickle from the level opening.
• Install a new sealing washer and thread the level plug in by hand while fluid is reduced to a thin trickle.
• Use the 11mm socket and torque wrench to tighten the level plug to 12 Nm (106 in-lbs).

Step 12: Reassemble and lower the vehicle

• Switch off the engine and remove the automotive scan tool.
• Use the 10mm socket, extension, and 3/8-inch-drive ratchet to reinstall the lower splash shield and its original fasteners. Tighten the small shield fasteners snugly without stripping them.
• Use the hydraulic floor jack to remove each jack stand and lower the Malibu carefully.
• Remove the wheel chocks.

✅ After Repair

• ✅ Start the engine and verify that Reverse and Drive engage normally without unusual delay.
• 🚗 Road-test your Malibu for 10-15 minutes using gentle acceleration. Confirm that shifts are smooth and no warning message appears.
• 🔍 Park on a clean, level surface and inspect the drain and level-plug areas for leaks.
• 🧰 Check the scan tool for transmission-related diagnostic trouble codes if a warning light, slipping, harsh shifting, or delayed engagement occurs.
• ⚠️ If the old fluid contained metal chips, smelled severely burned, or the transmission already slips, stop driving and have the transmission professionally diagnosed.
• ♻️ Take the used automatic transmission fluid to an authorized recycling center. Do not pour it onto the ground or into a drain.
