Apply Components
Overdrive (4R44E)/Front (5R55E) Band
Hydraulic pressure is applied to the front side of the front servo.
-
This pressure causes the servo to stroke and apply force to the band.
-
This action causes the front brake and coast clutch drum to be held.
-
4R44E: The front band holds the overdrive/front brake and coast clutch drum to the case in 4th gear.
-
5R55E: The front band holds the front brake and coast clutch drum to the case in 2nd and 5th gears.
-
This causes the front sun gear to be held stationary through the coast clutch adapter and the front brake and coast clutch drum.
