The 4L60E transmission, also known by the 4L60 transmission, was first introduced in 1992 to replace the 700R4 transmission. They were largely identical, however the main difference was the change from hydraulically to electronically controlled transmissions.

This transmission was developed and produced by General Motors/Hydramatic.

The 4L60E transmission was widely accessible in a wide range of GM truck, van, and SUV applications, as well as in rear-wheel drive car applications. Some of the most sought-after car models were the Chevrolet Corvette, Camaro, Caprice and Impala just to mention just a few. You will get more info about 4L60E transmission by visiting our site.

Although a variety of distinctions exist, the easiest to spot externally is that the bell-housing is movable for the Late 4L60E transmissions.

Although the replacement was initiated in 1996, it wasn't fully completed until 1998. The transmission isn't as widespread as it used to be however there are still uses for this transmission. The transmission is found in light-duty van applications and also in the overseas market in the Holden Commodore.

The reason for its popularity was several features that carry over, such as the ability to run at low speeds and strong fuel economy performance, while the introduction of electronic control also significantly improved the performance of this transmission.

One of the most common issues with this transmission is that it is unable to reverse gear, commonly caused by the buildup of debris.
