It was designed for compact FWD applications and is part of GMs family of technologically advanced, fuel-saving six-speed automatic transmissions. Shared traits between the 6TXX family and other Hydra-Matic six-speeds is to reduce complexity, size and mass, including clutch-to-clutch operation that enables the six-speed to be packaged into approximately the same space as a four-speed automatic. Sixth gear, however, is an overdrive ratio, which keeps the engine revolutions lower for highway cruising, reducing engine friction losses and optimizing fuel economy. The advantages of this layout enables a shorter overall vehicle length, more interior room and lower powertrain height. Freewheeling mechanisms allow accurate timing between shifts, but also take up more space and add more components to the transmission. Through electronic controls, the clutch-to-clutch concept of the 6T30 delivers optimal shift timing. The first-to-second upshift, however, is a freewheeling action, where the second gear clutch engages while the first gear one-way clutch spins freely. This allows a greater degree of smoothness at lower vehicle speeds. This takes advantage of engine braking to prevent unwanted acceleration. Gm 6T30 Transmission Driver To BrakeThis reduces the number of brake applies for the driver to brake during a hill descent. The control module receives input that monitors brake pedal usage, vehicle acceleration rate, throttle position, and even whether a trailer is connected to the vehicle. This design reduces the thickness of the torque converter, reducing the space it needs and keeping the overall width of the engine and transmission as narrow as possible for packaging advantages. The single-plate converter clutch uses GMs electronically controlled capacity clutch (ECCC) technology to help reduce engine vibrations and ensure smooth operation. The pump features an IX gear (DriveDriven) with a machined crescent in the pocket to reduce internal leakage and optimizes hydraulic efficiency. The inlet jet nozzle feature in the IX gear-type pump provides increased pump suction velocity, which helps optimize noise and vibration characteristics. With closer tolerances, the gears are less prone to characteristic whining or humming, allowing the transmission to operate with exceptional quietness.
