New transmissions were built by General Motors for the 1991 year of production. This included the 4L80E and smaller gear ratio designs. Different trucks and SUV platforms have used the four-speed automatic transmissions to achieve a balance of power. This website provides the place to buy used Chevy Avalanche 4L80E transmission inventory for close to a wholesale price online.
The internal code for all 4L80E gearboxes is M1. The exact gear rating can be different for each model produced although there are a total of five gears counting reverse. The manufacturing plant in Michigan has been the location GM has used to produce its updated turbo-hydramatic technology gearboxes for its fleet of motor vehicles.
Reliable Four-Speed Used Transmissions
Regardless of the published GM specs, current owners of the 4L80E transmissions know how useful these units are during vehicle operation. Chevrolet vehicles are not the only types that depend on the electronic torque system. The Hummer, Jaguar, Bentley and HD trucks built in the early 2000s have promoted the 4L gearboxes across the globe.

Buying a certified used gearbox is the only way to ensure an uninterrupted usage period.
