DESCRIPTION
The C6 transmission is a three speed unit Capable of
providing automatic upshifts and downshifts through
the three forward gear ratios. The transmission Is also
capable of providing manual selection of first and
second gears.
Fig. 1 shows the location of the converter, front pump,
clutches, gear train and most of the Internal parts used
in the C6 transmission. The identification tag (Fig. 2),
is attached to the intermediate servo lower front cover
bolt. The first line On the tag shows the transmission
model prefix and suffix. A number appearing after the
suffix indicates that the internal parts in the
transmission have been changed after initial
production start-up. For example, a PGD-BN model
transmission that has been changed internally would
read PGD-BN1. Both transmissions are basically the
same, but some service parts in the PGN-BN
transmission are slightly different than the PGD-BN1
transmission. Therefore, it is important that the
codes on the transmission identification tag be
checked when ordering parts or making inquiries
about the transmission.
The hydraulic control system schematic is shown in
Fig. 3. The converter housing and the fixed splines
which engage the splined outside diameter of the low-
22
reverse clutch steel plates, are both cast integrally
23
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.
