It isn’t necessary to check the transmission fluid level. The only reason for the fluid loss is a transmission fluid leak. If a leak occurs, take the vehicle to your dealer and have it fixed as soon as possible. There’s a specific method for checking and changing the transmission fluid. Because this process is complicated, you should have it done at your local dealership instead of doing it yourself.

The 2019 Buick Cascada is powered by a 1.6-liter turbocharged four-cylinder engine with 200 horsepower and is paired to a six-speed automatic transmission. It’s underpowered and out of date, and when cornering, it produces a significant body roll that no one will enjoy on a Sunday drive. Although the Cascada’s starting price is significantly lower than its premium competition, it does not provide good value in the market. The Cascada will be discontinued after this model year in the United States.
