Why does my car jump gears from drive to parking

Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. I'm sorry to hear you're having trouble with your 740i. It sounds like there may be an issue with your car's transmission or the shift linkage. Sometimes, a malfunctioning transmission control module (TCM) or issues with the shift linkage can cause the vehicle to shift into park unexpectedly. Another possibility is a problem with the transmission's internal components, such as the parking pawl, which locks the transmission in place when in park, or low transmission fluid, which can affect gear shifting. A malfunction in the electronic control system or a failure in the transmission can lead to erratic shifting. I recommend having the transmission fluid levels checked and scanning the car's computer for any error codes related to the transmission system. If you need more advice, have any other questions about your vehicle, or would like to get connected to a RepairPal Certified shop near you, we have you covered.
