🔧 Transmission Fluid - Drain and Refill

This service removes old automatic transmission fluid and replaces it with fresh fluid. Your Equinox uses a sealed-style transmission, so the final level has to be set correctly with the vehicle level and the fluid at the proper temperature.

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

⚠️ Safety & Precautions

• Work on a completely level surface. A wrong angle can give a wrong fluid level.
• Exhaust and transmission fluid can be hot. Let the vehicle cool before starting.
• Use jack stands. Never rely on a floor jack alone.
• This transmission level check requires the fluid temperature to be monitored with a scan tool.
• Do not overfill. Too much fluid can cause shifting problems and leaks.
• No battery disconnect is normally required for this service.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Raise and support the vehicle

• Use a floor jack to raise the vehicle on level ground.
• Place jack stands under the proper support points.
• Make sure the vehicle is level before draining.

Step 2: Remove the splash shield

• Use an 8mm socket to remove the lower splash shield fasteners.
• Set the shield and hardware aside.

Step 3: Drain the transmission fluid

• Place a drain pan under the transmission pan.
• Use the correct socket or ratcheting wrench to remove the drain plug.
• Let the fluid drain fully.
• Inspect the fluid for metal debris or a burned smell.
• Install a new drain plug seal if equipped.
• Torque the drain plug to 24 Nm (18 ft-lbs).

Step 4: Remove and replace the pan gasket if servicing the pan

• Use a 10mm socket to remove the transmission pan bolts.
• Lower the pan carefully. A little fluid may still be trapped inside.
• Clean the pan and magnet with clean shop towels.
• Install the new pan gasket.
• Reinstall the pan and start all bolts by hand.
• Torque the pan bolts to 11 Nm (97 in-lbs).

Step 5: Refill with fresh fluid

• Locate the transmission fill port.
• Use a fluid pump with hose to add DEXRON-VI fluid.
• Add fluid slowly.
• Start with about 4-5 quarts, then continue during the level check.
• Do not guess the final level.

Step 6: Warm the transmission and check the level

• Start the engine and keep the vehicle level.
• Use the scan tool to watch transmission fluid temperature.
• With the engine running, move the shifter through each gear position, pausing briefly in each one.
• Return to Park.
• At the specified fluid temperature range, remove the level check plug.
• If fluid dribbles out, the level is close. If nothing comes out, add fluid until it does.
• If fluid pours out strongly, let it drain until it reduces to a steady drip.
• Reinstall the level plug and torque it to 12 Nm (106 in-lbs).

Step 7: Reinstall the splash shield

• Use the 8mm socket to reinstall the shield fasteners.
• Make sure all clips and screws are secure.
