Why can't your Toyota Previa reverse?

If your Toyota Previa won't reverse, it could be due to several issues such as a malfunctioning transmission, low Transmission Fluid, or a faulty shift cable. Additionally, problems with the vehicle's brake system, such as a stuck brake pedal or issues with the brake light switch, could also prevent the car from engaging in reverse. It's advisable to have a qualified mechanic diagnose the problem to ensure proper repairs.
