What gear should be used for the initial drive to warm up drive lines in cold conditions?

Using 3rd gear for the initial drive to warm up the drive lines in cold conditions strikes a balance between providing enough power to ensure proper warming while avoiding excessive strain on the vehicle components. In cold weather, fluids can be thick and sluggish, and starting in a higher gear helps to gradually increase engine and transmission temperatures without overwhelming the drivetrain.

This method promotes smoother operation and minimizes the risk of damaging the vehicle, as it allows for more controlled acceleration and helps ensure that all components reach optimal operational temperatures in a safe manner. Lower gears can engage the engine and drive line too aggressively in cold conditions, potentially leading to increased wear or even failure, while higher gears like 4th may not sufficiently engage the necessary components to warm them up effectively.
