How to Replace the Transmission Oil for a Buick Excelle Manual Transmission?
2 Answers
Buick Excelle manual transmission oil replacement steps are: 1. Start the engine and warm it up to normal operating temperature; 2. Remove the drain bolt to let the transmission oil flow out; 3. After the old transmission oil is drained, screw the bolt back in; 4. Add new transmission oil; 5. Start the car and perform gear shifting operations; 6. Check if the transmission oil level is normal. The Buick Excelle has a length of 4468mm, width of 1765mm, height of 1469mm, a wheelbase of 2611mm, a body type of 4-door 5-seater sedan, a 5-speed manual transmission, and a top speed of 170 kilometers per hour.
I've changed the transmission oil several times myself and find the process not too complicated, but it requires some patience and tools. First, park the car on level ground and engage the handbrake. For safety, use a jack or stands to lift the front wheels. There's usually a drain plug under the transmission, located at the left rear or center of the chassis. Use a properly sized wrench or socket to loosen it and let the old oil drain slowly into a container. Once fully drained, tighten the plug back. The key to adding new oil is finding the fill hole, typically nearby, often marked by a small capped plug. Use a funnel to prevent spills when pouring, and fill until oil just starts to overflow—too much or too little can affect gear shifting. I prefer using manufacturer-recommended oils like 75W-90; after changing, the car feels much smoother. Having a measuring cup and oil catch pan is practical—the whole job takes about half an hour and saves on repair costs. Remember to test drive afterward to check for unusual noises and address any issues promptly.
