The 4L60-E transmission is typically rated to handle around 350 to 400 horsepower in stock form. However, with upgrades such as stronger clutches, better torque converters, and improved cooling systems, it can manage up to 500 horsepower or more. It's important to note that exceeding these limits can lead to premature failure, especially under heavy loads or aggressive driving conditions. Proper maintenance and tuning also play a crucial role in the longevity of the transmission.
