What vehicles have a 4l80e transmission?

The 4L80E transmission has been used in a wide variety of vehicles, primarily larger, heavier vehicles needing high torque capacity. It's not easy to give an exhaustive list, as different model years and trim levels may or may not include it, but here are some examples of vehicle types and brands that commonly used (or use) the 4L80E:

* Chevrolet: Suburban, Tahoe, Yukon, Silverado, Avalanche, Express vans (particularly heavier duty models)

* GMC: Yukon, Sierra, Savana vans (again, heavier duty models)

* Cadillac: Escalade

* Hummer: H2

* Various other GM vehicles: Many other large trucks, SUVs and vans built by GM (and some non-GM vehicles using GM powertrains) over the years could feature the 4L80E.

It's important to note that this transmission was often available as an option, and some models came with other transmissions. To be absolutely certain if a specific vehicle has a 4L80E, you should check the vehicle's specifications or the transmission identification tag located on the transmission itself.
