The GM 6T30 / 6T40 / 6T45 / 6T50 Transmission Rebuild Manual, published by ATSG, is a great educational tool for getting a firm handle on the six speed, fully automated tranny. First introduced in 2007 as part of the Chevy Captiva, everyone was impressed with the electronically controlled, all wheel drive manufacturing and its clutch to clutch shifting.

This thorough transmission rebuild resource is the place to turn to for management of wiring schematics, disassembly and reassembly of the 3-5-reverse, electronic component operation, trouble code diagnostic, trans disassembly and check ball location. This ATSG manual is the place for differentiating the unit's five variations, learning how to effectively check for excessive valve clearance and why you don't want to use cloth or paper towels to clean valve parts.

These Hydra-matic trannys quickly became a go-to for the small crossover, mid-size and compact vehicles. The 6T30 and 6T40 are also a favorite for hybrids. Known as the GF6, this series consists primarily of four element torque converters, five clutch packs, three planetary gear sets, a hydraulic pressure and control system, and a mechanical one way clutch. The TCM monitors electronic sensor inputs, translating information so that the transmission shifts at optimum moments. Through the TCM, gear change ratios are fully automated.

The GM 6T30 / 6T40 / 6T45 / 6T50 Transmission Rebuild Manual is a library of comprehensive and focused procedures for diagnosing, overhauling and maintaining GM's 6T30/40/45/50 transmission from the perspective of professional technicians. It's going to give every tech a new perspective on the best ways to save money and time on the production of these trannys.
