What to Do About Slow Automatic Upshifting?

[VonCameron]

If the automatic transmission is slow to upshift, it may be due to a malfunctioning shift solenoid valve. You can have it repaired at a 4S shop. Below is relevant information about automatic transmissions: Definition of Automatic Transmission: An automatic transmission typically refers to a car's automatic gear-shifting mechanism. While driving, the automatic transmission's control system selects the appropriate gear based on the engine's speed and load, replacing the driver's subjective judgment of timing and shifting operations. Principle of Automatic Transmission: An automatic transmission uses planetary gear mechanisms to change gears. It automatically shifts gears based on the degree of throttle pedal input and changes in vehicle speed. The driver only needs to control the speed by operating the accelerator pedal.
