A service technician says drivers are damaging their car’s transmission by not using the parking brake regularly. The warning came from a viral TikTok post by John Hiester Automotive Group, and it matters because transmission repairs cost a lot of money. The dealer employee asked a mechanic if drivers should always use their parking brake.
According to Motor1, The mechanic explained why you need to use the brake every time you park. Not using it causes long-term damage to your car’s expensive parts. When you skip this step, all the pressure goes straight to your transmission, hitting a small but important piece called the parking pawl.
