Product Overview
This is the DOWNLOAD link for The new Hydra-matic 6T70/75 (6 Speed) TechTran. The 6T70/75 is a fully automatic, six speed, front wheel drive, electronicallycontrolled transmission that features clutch to clutch shifting. It is also all-wheel drive capable. It was first introduced in the 2007 model year in several different models, as shown in Figure 1. It consists primarily of a fourelement torque converter, three planetary gear sets, five clutch packs, one mechanical one-way clutch and ahydraulic pressurization and control system. Three planetary gear sets provide the six forward gear ratios andreverse. Changing gear ratios is fully automatic and is accomplished through the use of a Transmission ControlModule (TCM), that is located within the transmission. The TCM receives and monitors various electronic sensorinputs, and uses this information to shift the transmission at the optimum time. The TCM commands shift solenoidsand variable bleed Clutch Pressure Control (CPC) solenoids within the transmission to control shift timing. TheTCM controls shift feel through the CPC solenoids. The TCM also controls the apply and release of the torqueconverter clutch which allows the engine to deliver the maximum fuel efficiency without sacrificing vehicleperformance. This manual contains the procedures necessary to diagnose, overhaul and/or repair the new 6T70/75(6 Speed) transmission from General Motors.
