Common problems with Chevrolet Cobalt automatic transmission:
* Gear Slip: Gear slip occurs when the automatic transmission is unable to efficiently transfer power from the engine to the wheels, resulting in loss of power and reduced acceleration.
* Shock when shifting gears: Severe knocks when shifting gears indicate problems with the shift valves or valve body of the automatic transmission.
*Lagging Shift: A delayed shift indicates a problem with the torque converter or valve body.
*Transmission Fluid Leak: Transmission fluid leaks can be caused by damaged seals or hoses, which can result in low fluid levels and damage to the transmission.
* Overheating: Overheating of the automatic transmission can be caused by a lack of transmission fluid, clogged oil filters or a faulty transmission fluid cooler.
