Does a 1990 gm truck have 4l60e transmission?

While the 4L60E transmission was introduced in 1990, not all 1990 GM trucks used it. The 4L60E was becoming more common in that year but wasn't universally adopted across all models and engines. Whether a specific 1990 GM truck had a 4L60E depends on the:

* Model of the truck: Larger trucks might have used a heavier-duty transmission.

* Engine size: The transmission was paired with specific engines.

* Specific trim level: Some options might have included different transmission choices.

To know for sure if *your* 1990 GM truck has a 4L60E, you need to check the vehicle's identification number (VIN) or look at the transmission identification tag on the transmission itself.
