Many engine builders will tell you never downshift to slow a car down. Down shifting at a high speed puts a strain on the engine. It is better to use your brakes than use the engine/transmission to slow down. You’re not driving a race car with a disposable engine. The Corvette owners manual also states to use your brakes. Down shifting should be done at lower speeds to avoid lugging the engine. To each his own.
