What are the consequences of using D gear for climbing?

[Jocelyn]

Using D gear for climbing may lead to the following consequences: 1. The L gear is commonly found in CVT continuously variable transmissions. Unlike gear-type transmissions, CVT transmissions rely on steel belt drives, so there is no fixed gear ratio to amplify torque when climbing. In this case, an L gear (low gear) is needed to achieve low speed and high torque. If you directly switch from D gear to L gear at high RPM, it may cause the steel belt to slip, damaging internal transmission components. 2. Moreover, using D gear when the vehicle is heavily loaded and climbing a long slope can easily cause the CVT transmission to overheat. It is recommended to use L gear during continuous uphill driving to allow the engine to maintain maximum torque output for climbing. When using L gear for climbing, the transmission ratio continuously changes based on vehicle speed and torque conditions, with the variation limited to a small range.
