6T30 Automatic Transmission Service Manual
This series of transmissions is also known as the GF6. It consists primarily of a four element torque converter, three planetary gear sets, five clutch packs, one mechanical one-way clutch and a hydraulic pressurization and control system. Three planetary gear sets provide the six forward gear ratios and reverse. Changing gear ratios is fully automatic and is accomplished through the use of a Transmission Control Module (TCM) that is located within the transmission. The TCM receives and monitors various electronic sensor inputs, and uses this information to shift the transmission at the optimum time. The TCM commands shift solenoids and Clutch Pressure Control (CPC) solenoids within the transmission to control shift timing. The TCM controls shift feel through the CPC solenoids. The TCM also controls the apply and release of the torque converter clutch which allows the engine to deliver the maximum fuel efficiency without sacrificing vehicle performance.
This automatic transmission service group manual contains the procedures necessary to diagnose, overhaul and-or repair the 6T30, 6T40, 6T45, 6T50, 6 Speed, GEN 1 and GEN 2 transmissions from General Motors.
