How can you identify a 4L65E?

Answer 1

The 4L65E transmission can be identified by its distinctive features, including a metal identification tag typically located on the passenger side of the transmission case. It has a rectangular shape with a separate bellhousing, and the case is made from aluminum. Additionally, it has a 4-speed design with an electronic control system. You can also recognize it by the presence of a 30-spline output shaft, which differentiates it from similar models like the 4L60E.
