How long did general motors use the 4l60e transmissions?

General Motors used the 4L60E transmission for a remarkably long time, roughly from 1990 to 2006. However, it's important to note that this is a generalization. Different variations and iterations of the 4L60E were used throughout those years, and its application varied by vehicle and model year. Some vehicles may have transitioned to a different transmission before 2006, while others continued using updated versions of the 4L60E even later.
