Introduced in 2006, the 6L80 has become the most popular General Motors
transmission in production today. Millions are on roads around the
world, and the 6L series of transmissions has overtaken the 4L60E as the
most popular rebuild in the majority of transmission shops and
dealerships today.
Automatic transmissions are often seen as mysterious and overly
complicated, but much of the guesswork has been simplified to its basic
elements in this easy-to-follow guide. This book covers the
identification process, operation, diagnostic pointers, common failures,
and repair and rebuild procedures for the 6L80 transmission. Upgrades
that are available to make the 6L80 more robust are covered as well as
the companies that offer upgrades.
This detailed, step-by-step instructional manual is authored by
engineer, instructor, speaker, and author Steve Garrett. Meticulous
step-by-step photos of the rebuild process are featured along with
torque specifications and identification of all major and most minor
components.
