The C6 transmission is a three

speed unit capable of providing auto-

matic upshifts and downshifts through

the three forward gear ratios, and also

capable of providing manual selection

of first and second gears. The hydrau-

lic control system schematic is shown

in Figure 3. The converter housing

and the fixed splines which engage the

splined OD of the low-reverse clutch

steel plates, are both cast integrally

into the case.

Only one (intermediate) band is

used in the C6 transmission. This

along with the forward clutch is used

to obtain intermediate gear.

The only adjustment on the trans-

mission proper is the intermediate

band.

The fluid is drained from the trans-

mission by loosening the pan bolts

and allowing it to drain. Finally, to

allow the pan to drain more thorough-

ly, remove all bolts except the two

from the front.procarmanuals.com
