How many liters of transmission fluid does the Excelle require?
2 Answers
The Buick Excelle's automatic transmission fluid capacity is 8.2L, but typically only 4L is needed during replacement. The manual transmission fluid capacity is 1.8L, with approximately 2L required for replacement. The dual-clutch transmission fluid capacity is 2.45L. Functions of transmission fluid: Transmission fluid primarily maintains the cleanliness of the gear system and provides lubrication to the transmission components to extend their service life. Transmission fluid replacement methods: Gravity drain: Using tools to loosen the drain plug, allowing the transmission fluid to flow out naturally under gravity. Machine flush: The flush machine connects to the transmission's fluid circuit, using hydraulic pressure to push out the old fluid with new fluid.
Last time I helped my friend maintain his Buick Excelle, we talked a lot about transmission fluid. Generally, automatic transmission fluid capacity is around 5 to 6 liters, while manual transmissions require less, probably 3 to 4 liters. But remember, the exact amount depends on the model year and transmission type - newer models might have more fuel-efficient designs. During inspection, I also noticed that overfilling can cause leaks or overheating, while low levels may damage gears. That's why I always recommend checking the owner's manual first or visiting a professional shop for precise measurement with proper tools. Don't delay fluid changes beyond 40,000 km to prevent carbon buildup clogging the system. Overall, DIY fluid changes can save hundreds, but first-timers often make mistakes, so it's safer to visit certified repair shops.
