What Does Stall Mean?
1 Answers
Stall refers to the phenomenon where the output speed of the torque converter is zero while the engine is running, meaning the pump wheel rotates while the turbine remains stationary. Traditional automatic transmissions experience stalling, which is why the engine idles during gear shifts, leading to delayed shifting. Essentially, a car stall test involves placing the transmission in drive or reverse gear, fully depressing the brake pedal, and simultaneously pressing the accelerator pedal to the floor to measure the maximum engine speed achievable.
