One, or a combination of selective washers are used be-
tween the input shaft flange and the number 4 bearing to
control the transmission end float. This arrangement al-
lows for extensive subassembly testing and simplistic fi-
nal assembly during production.
A general description of the operation of the Power Train
System is detailed below.
First gear is engaged by applying the C2 clutch and lock-
ing the 1-2 One Way Clutch (1-2 OWC). The 1-2 shift is
accomplished by applying the B1 band and overrunning
the 1-2 OWC. The 2-3 shift is accomplished by applying
the C1 clutch and releasing the B1 band. The 3-4 shift is

accomplished by re-applying the B1 band and overrun-
ning the 3-4 OWC. Reverse gear is engaged by applying
the C3 clutch and the B2 band.
The C4 clutch is applied in the Manual 1, 2 and 3 ranges
to provide engine braking. In addition, the C4 clutch is
also applied in the Drive range for second and third gears
to eliminate objectionable freewheel coasting.
The B2 band is also applied in the Manual 1 range to ac-
complish the low-overrun shift.
Both the front and rear servos are dual area designs to
allow accurate friction element matching without the need
for secondary regulator valves. All the friction elements
have been designed to provide low shift energies and high
static capacities when used with the new low static co-
efficient transmission fluids. Non-asbestos friction materi-
als are used throughout.
