What Kind Of Transmission Fluid Does a Buick Lacrosse Take?
The 2019 Buick LaCrosse has a 9-speed automatic gearbox that requires Dexron VI transmission fluid. The vehicle’s capacity is 10 quarts for the total fill.
Transmission fluid is essential for gear shifts, transmission cooling, and lubrication of moving parts. The transmission has an expected lifespan of around 150,000 miles. It’s a good idea to change the fluid every 45,000 miles or so. Fluid replacement costs between $8 and $13 per quart, depending on the brand. The labor charge for changing the fluid at a mechanic ranges from $50 to $60, as well as any additional parts fees.
