Clutch packs
▶
There are four clutch packs. All clutch packs
are composed 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.
