Automatic Transmission Car Rolls in Park
What is the Problem?
When you put your automatic transmission car in park, the transmission is supposed to lock the output shaft of the transmission, preventing the car from moving. However, in some cases, the car may still roll in park. This can be a dangerous problem, as it can cause the car to move unexpectedly and cause an accident.
What Causes the Problem?
There are several different things that can cause an automatic transmission car to roll in park. Some of the most common causes include:
* Low transmission fluid: If the transmission fluid level is low, it can cause the transmission to slip, which can allow the car to roll in park.
* Worn transmission bands: The transmission bands are responsible for locking the output shaft of the transmission. If the bands are worn, they may not be able to hold the car in place.
* Faulty transmission valve body: The transmission valve body controls the flow of transmission fluid. If the valve body is faulty, it can cause the transmission to shift out of park into another gear.
* Damaged parking pawl: The parking pawl is a small metal lever that locks the transmission in park. If the parking pawl is damaged, it may not be able to hold the car in place.
