Does Stomping on the Accelerator in an Automatic Transmission Damage the Car?

[MacAlexa]

Stomping on the accelerator can indeed damage the car. Here are the potential harms of stomping on the accelerator: 1. Stomping on the accelerator causes the automatic transmission to immediately force a downshift, as the transmission performs a "forced downshift." This can easily lead to excessively high engine RPM, increasing wear on the friction plates in the automatic transmission and raising the temperature of the transmission fluid. As a result, it can harm your transmission and damage the car. 2. The acceleration gained from stomping on the accelerator often involves some degree of engine revving without proportional power delivery, as inertia cancels out much of the force. In terms of efficiency, this is not very cost-effective, and rapid acceleration further accelerates tire wear. 3. When releasing the accelerator, the car's engine also experiences a sudden, significant drop in RPM, repeatedly pulling back against the car's momentum. This is similar to how downshifting to slow down is better than coasting in neutral—traction force turns into resistance.
