General Motors Transmission Shudder With 6L80E, 6L90E, & 8L90E

The 6L80E, 6L90E, & 8L90E are a heavy-duty automatic transmission found in a variety of General Motors vehicles, including the Chevrolet Silverado, GMC Sierra, and Cadillac Escalade. Although it is a dependable transmission, it can develop issues over time. Shuddering, a vibration or shaking that happens as the gearbox shifts gears, is one of the most typical issues.

There are numerous factors that can make these transmissions shudder. A torque converter that is worn out or damaged is one common cause. The torque converter is a fluid coupling that transfers power from the engine to the transmission. It can produce shuddering or trembling as the transmission shifts gears if it is worn out or damaged.

Low levels of fluids are another frequent reason for transmission problems. The transmission fluid assists in cooling and lubricating the transmission. The transmission can shudder when changing gears if the fluid level is low.

Finally, shuddering can also be caused by a problem with the transmission control module (TCM). The TCM is a computer that controls the operation of the transmission. If it is faulty, it can cause shuddering when the transmission is shifting gears.

If you are experiencing shuddering in your 6L80E transmission, it is important to have it diagnosed by a qualified mechanic. The mechanic will be able to determine the cause of the shuddering and recommend the best course of action to repair the problem.
