For example, the first digit signifies the year (e.g., 4 = 2004), the second digit denotes the model, and the sixth to seventh digits represent the Julian date or day of the year. These tags contain information such as the model year, assembly number, and production date. Observing this difference can help in identification.Ĭase Tags: Another useful method to identify a 4L60E transmission is by deciphering the case tags. The earlier versions (1993-1997) had a one-piece case, while later models (1998 and up) featured a two-piece case.

Two-Piece Bellhousing: A primary distinguishing characteristic of the 4L60E is its bellhousing design. To correctly identify a 4L60E transmission, there are several key features to look for. The 4L60E transmission is a popular choice in many vehicles due to its versatility and performance. They all are shifted by the vehicles ECM.They can be purple or green, depending on the year ALL 4L60E transmissions have a 12-pin connector from the harness.Here are a few characteristics that all years share These eras are easy to identify from the outside of the transmission. The 4L60E bellhousing can bolt to either engine, although you may need an adapter to get a Gen III transmission to bolt to Gens I and II and vice versa.įor the purposes of easy identification, we have broken the 4L60E into four distinct eras. When it was introduced, the original small-block Chevy engine was still in production, and it was retained for the LS Gen III line of engines. The 4L80E was used for heavier-duty trucks.

The 4L60E was utilized in cars and light-duty trucks. the “E” at the end of 4L60 indicates that it is electronically controlled.ĤL60E Identification can be quite a chore since the transmission has been in production for so long. The 4L60E transmission has been in production for over twenty years, even longer if you consider the fact that it came from the 4L60 (700R4). If you’re looking to tell the 4L60E model year, read on… If you’re trying to figure out whether or not the transmission you are looking at is a 4L60E, this pan identification guide will be enough.
