DESCRIPTION AND OPERATION
Transmission Description
The 4R70W has the following features:
zWide ratio gears
z Four speeds
z Rear wheel drive
z Automatic
z Electronic shift
z Torque converter clutch control
z Line pressure controls
The transmission uses Ravigneaux- style double-pinion gearset with two bands, one one- way roller
clutch, one mechanical diode and four friction clutches to produce four forward gears and Reverse.

z
Apply and release of the torque converter clutch.
z Maximum fuel economy during normal operation.
Second Position
This position provides:
zSecond gear start and hold.
z The torque converter clutch can apply and release.
z Improved traction and engine braking on slippery roads.
z Engine braking for descending steep grades.
First Position
If this position is selected at normal road speeds, the transmission will shift into second gear, then into
first when the vehicle reaches a speed below approximately 45 km/h (28 mph).
This position provides:
zFirst gear operation only.
z Engine braking for descending steep grades. Klj . 2 ba

DESCRIPTION AND OPERATION
Shift Patterns
Upshifts
Transmission upshifting is controlled by the powertrain control module (PCM). The PCM receives
inputs from various engine or vehicle sensors and driver demands to control shift scheduling, shift feel
and torque converter clutch (TCC) operation.
Downshifts
Under certain conditions the transmission will downshift automatically to a lower gear range (without
moving the gearshift lever). There are three categories of automatic downshifts; Coastdown, Torque
Demand and Forced or Kickdown shifts.
Coastdown
The coastdown downshift occurs when the vehicle is coasting down to a stop.
Torque Demand
The torque demand downshift occurs (automatically) during part throttle acceleration when the
demand for torque is greater than the engine can provide at that gear ratio. If applied, the transmission
will disengage the TCC to provide added acceleration.
Kickdown
For maximum acceleration, the driver can force a downshift by pressing the accelerator pedal to the
floor. A forced downshift into a lower gear is possible below calibrated speeds. Specifications for
downshift speeds are subject to variations due to tire size, engine and transmission calibration
requirements.
