Exploded View Of C6 Transmission, (Part 3 Of 3):

As shown in the Exploded View Of C6 Transmission, the transmission consists essentially of a torque converter, a compound planetary gear train controlled by one band, three disc clutches and a one-way clutch, and a hydraulic control system.

OPERATION
The normal automatic driving range is D. In this range, the car starts off in first gear and gives the best combination of automatic gear shifts to provide for economy and full power starts. As the accelerator is depressed and the car picks up speed, automatic shifts to second and high gear will occur. The transmission will automatically downshift as speed decreases. Forced downshifts in drive are made in the same manner as with earlier models.

Second Gear Hold
With the shift lever in 2, the car will start off in first gear and shift to second gear. The transmission will remain in second gear, regardless of throttle opening or road speed. When engine braking is required and the selector lever is moved from D to 2, the transmission will downshift to second gear. The second gear range is not a cruising range in the usual sense of the term.

1, LOW
The 1 range is identical in operation to manual low range. This range is especially useful for starting the car on icy pavements or other slippery surfaces. The automatic shift from intermediate to low gear will occur at 15-25 mph.
