Torque Converter

The torque converter consists of a turbine, stator pump,
impeller and a lock-up damper and piston assembly.
As in conventional torque converters, the impeller is
attached to the converter cover, the turbine is splined
to the input shaft and the stator is mounted on the
pump housing via a one way clutch (sprag).

The addition of the damper and piston assembly en-
ables the torque converter to lock-up under favorable
conditions. Lock-up is only permitted to occur in third
and fourth gears under specified throttle and vehicle
speed conditions.

Lock-up is achieved by applying hydraulic pressure
to the damper and piston assembly which couples the
turbine to the converter cover, locking-up the converter
and eliminating unwanted slippage. Whenever lock-
up occurs, improved fuel consumption is achieved.
Torsional damper springs are provided in the damper
and piston assembly to absorb any engine torque
fluctuations during lock-up.

Clutch Packs

There are four clutch packs. All clutch packs are com-
posed of multiple steel and friction plates.

C1 CLUTCH: When applied, this clutch pack allows
the input shaft to drive the planet carrier. This occurs
in third and fourth gears.

C2 CLUTCH: When applied this clutch pack allows
the input shaft to drive the forward sun gear via the 3-
4 OWC. This occurs in all forward gears.

C3 CLUTCH: When applied this clutch pack allows
the input shaft to drive the reverse sun gear. This only
occurs in reverse gear.

C4 CLUTCH: When applied this clutch provides engine
braking on overrun. This occurs in Manual 1, 2 and 3
and also Drive 2 and Drive 3 to prevent objectionable
free wheel coasting.

Bands

The transmission utilizes two bands, the B1 band
(sometimes known as the 2-4 band), and the B2 band
(sometimes known as the low-reverse band).

The B1 band is a flexible band which is engaged by
the front servo piston. B1 is activated in second and
fourth gear. When activated B1 prevents the reverse
sun gear from rotating by holding the C3 clutch
assembly stationary. In second gear only the outer

area of the apply piston is utilized. In fourth gear both
areas are utilized for greater clamping force.

The B2 band is a solid band which is engaged by the
rear servo piston. B2 is activated in Park, Reverse,
Neutral and Manual 1. When activated B2 prevents
the planet carrier assembly from rotating. In Manual 1
only the inner area of the apply piston is utilized. In
Park, Reverse and Neutral, both areas are utilized for
greater clamping force.

One Way Clutches

The transmission uses two OWCs, the 1-2 OWC and
the 3-4 OWC. (Note that a third OWC is located in the
torque converter, also known as a sprag.)

The 1-2 OWC is located between the planetary carrier
assembly and the center support. This allows the carrier
to rotate around the center support in one direction
only. The one way clutch is engaged only in Drive 1.

This 3-4 OWC is located between the C4 and the C2
clutch assemblies. This allows the C2 clutch to drive
the forward sun gear in first, second and third gears
but unlocks in fourth gear and during overrun.

Planetary Gear Set

The planetary gear set used in the transmission is a
conventional six pinion Ravigneaux compound gear
set.

Parking Mechanism

When Park is selected the manual lever extends the
park rod rearwards to engage the parking pawl. The
pawl will engage the external teeth on the ring gear
thus locking the output shaft to the transmission case.
When Park is not selected a return spring holds the
parking pawl clear of the output shaft, preventing
accidental engagement of Park.
