How to Deal with MG 3 Transmission Failure?
2 Answers
Here is the relevant introduction about the causes and solutions for MG 3 transmission failure: 1. Transmission contamination: The damage to the transmission valve body is mostly caused by the transmission oil inside being too dirty, leading to valve body damage. It is necessary to check whether the valve body is damaged. If the inspection reveals damage, a new transmission valve body needs to be replaced. Solution: Regularly replace the transmission oil to avoid transmission failure. 2. Bearing damage: The wear of the transmission bearing causes the output shaft to move non-concentrically, changing the chamfer of the transmission's output and input. Sometimes, there may be phenomena like gear biting or gear slipping, which can lead to the transmission braking or getting stuck. Solution: A brand-new transmission bearing needs to be replaced.
I've been driving a MG 3 for several years and encountered transmission issues a few times. If the warning light comes on or you feel gear shifting is rough, never continue driving, especially when sudden problems occur on highways - it's extremely dangerous. First, pull over safely, engage the handbrake and turn on hazard lights, then check the dashboard for error codes like P0700 which commonly indicates electronic control system issues. If there are no obvious warnings, simply inspect the transmission fluid - low level or darkened fluid often causes malfunctions. I recommend searching for nearby repair shops on your phone, contacting professional technicians for on-site inspection or arranging a tow truck. The MG 3 uses an AMT transmission, where minor issues like weak sensor signals can lead to major problems. Timely handling saves big money, and changing fluids more frequently during next maintenance will significantly help.
