One common problem is the failure of the transmission input drum. This drum connects the transmission to the engine and can fail due to excessive wear or a lack of lubrication. This can cause the transmission to slip or not engage properly.
Another common problem is the failure of the overdrive unit. This unit allows the transmission to shift into overdrive, which helps improve fuel economy. When the overdrive unit fails, the transmission will not be able to shift into overdrive, which can result in reduced fuel efficiency and performance.
Finally, the 4L60E transmission can also experience problems with the torque converter. The torque converter helps smooth out the power flow from the engine to the transmission. When the torque converter fails, it can cause the transmission to shudder or vibrate.
These are just some of the common transmission problems that can affect the 1997 Chevrolet Silverado. If you experience any of these problems, it is important to have your transmission inspected by a qualified mechanic.
