This S-A BOOKS manual walks through the complete GM 6L80 transmission rebuild from teardown to reassembly, written for technicians and hands-on builders who want to service or upgrade the six-speed automatic found behind countless GM truck and performance applications. Author Steve Garrett, an engineer and instructor, covers identification, operation, diagnostics, common failure points, and the upgrade paths that make the 6L80 hold up under more power. Across 144 pages, the book reads like a shop reference rather than a marketing piece, giving you the procedures and torque values needed to rebuild a 6L80 transmission correctly the first time.
The manual runs 144 pages in an 8.5 x 11 inch paperback format and includes 346 color photos that document the step-by-step rebuild process, component identification, and torque specifications throughout. Published by CarTech Inc in 2022, it identifies all major and most minor components so you can sort good cores from worn ones during inspection. Diagnostic sections point to the symptoms behind slipping, harsh shifts, and converter issues before you ever pull the unit. The upgrade chapters cover the parts and modifications that improve durability under added torque, which matters if you are pairing the trans with an LS or LT swap. For broader powertrain reading, TSA stocks related titles in our how-to books section.
Anyone diagnosing a failing 6L80, planning a rebuild on the bench, or building a transmission to survive a higher-output engine will get use out of this reference. The photo-driven layout makes it practical to keep open at the workbench while you work through each stage. If you are building a complete drivetrain, pair it with our other transmission manuals or browse the full books, videos, and software catalog at TSA for engine and chassis titles that round out the project.
