In cold weather, it is important to warm up not only the engine but also the transmission, and a seasoned driving expert explains how to do this safely and effectively.
A traditional automatic transmission, often a hydromechanical system, is particularly vulnerable when temperatures drop. The thickened transmission fluid struggles to generate the pressure needed to compress the clutch packs, which can lead to slipping. The same issue can also affect the torque converter, reducing its efficiency and potentially increasing wear. Automotive guidance emphasizes that warming the engine alone does not guarantee the transmission is ready for operation. Until the transmission fluid reaches an appropriate temperature, sudden acceleration should be avoided to protect the drivetrain. This perspective has been highlighted by the driving expert, who notes that a cautious warming process minimizes stress on internal components and extends transmission life.
To reduce risk, start the warming process with the gear selector in Drive or Reverse rather than Park or Neutral, and allow the vehicle to idle gently. The choice between Drive and Reverse depends on the vehicle’s parking position and surroundings. If the car is resting with its rear wheels on a curb, engaging Reverse and applying the handbrake is advisable. It is safest not to exit the vehicle during warm-up, given the possibility of surprises on the road or in traffic. Once the engine temperature reaches approximately 80 degrees Celsius, the transmission can be considered ready for regular operation, though drivers should still progress with smooth, progressive inputs and avoid aggressive throttle use during the initial minutes of driving.
