Buying Guide for 4L60E Transmission Rear Seal

Understanding the 4L60E Transmission

When I first started working on my vehicle, I quickly learned that the 4L60E transmission is one of the most common automatic transmissions used in various GM vehicles. It’s essential to understand how it functions, as this knowledge helps in identifying issues, including leaks that may occur at the rear seal.

Why the Rear Seal Matters

Over time, I noticed that the rear seal can wear out due to heat and pressure, leading to fluid leaks.
