SENSOR-INPUT SPEED
DESCRIPTION
The Input (1) and Output (2) Speed Sensors are two-
wire magnetic pickup devices that generate AC signals
as rotation occurs. They are mounted in the left side
of the transmission case and are considered primary
inputs to the Transmission Control Module (TCM).
OPERATION
The Input Speed Sensor provides information on how fast the input shaft is rotating. As the teeth of the input clutch
hub pass by the sensor coil, an AC voltage is generated and sent to the TCM. The TCM interprets this information
as input shaft rpm.
The Output Speed Sensor generates an AC signal in a similar fashion, thoughitscoilisexcitedbyrotationofthe
rear planetary carrier lugs. The TCM interprets this information as outputshaftrpm.
The TCM compares the input and output speed signals to determine the following:
Transmission gear ratio
Speed ratio error detection
CVI calculation
The TCM also compares the input speed signal and the engine speed signal to determine the following:
Torque converter clutch slippage
Torque converter element speed ratio
REMOVAL
1. Raise vehicle.
2. Place a suitable fluid catch pan under the transmis-
sion.
3. Remove the wiring connector from the input speed
sensor.
NOTE: The speed sensor bolt has a sealing patch
applied from the factory. Be sure to reuse the
same bolt.
4. Remove the bolt holding the input speed sensor to
the transmission case.
5. Remove the input speed sensor from the transmis-
sion case.

INSTALLATION
1. Install the input speed sensor (1) into the transmis-
sion case.
NOTE: Before installing the speed sensor bolt, it
will be necessary to replenish the sealing patch on
the bolt using MOPAR
Lock & Seal Adhesive.
2. Install the bolt to hold the input speed sensor into
the transmission case. Tighten the bolt to 9 Nꞏm
(80 in.lbs.).
3. Install the wiring connector onto the input speed
sensor
4. Verify the transmission fluid level. Add fluid as nec-
essary.
5. Lower vehicle.

SENSOR-VARIABLE LINE PRESSURE
DESCRIPTION
The line pressure sensor (2) is mounted on the top of
the valve body, next to the pressure control solenoid
(1).
The TCM utilizes a closed-loop system to control
transmission line pressure. The system contains a
variable force style solenoid, the Pressure Control
Solenoid. The solenoid is duty cycle controlled by the
TCM to vent the unnecessary line pressure supplied
by the oil pump back to the sump. The system also
contains a variable pressure style sensor, the Line
Pressure Sensor, which is a direct input to the TCM.
The line pressure solenoid monitors the transmission
line pressure and completes the feedback loop to the
TCM. The TCM uses this information to adjust its con-
trol of the pressure control solenoid to achieve the
desired line pressure.
OPERATION
The TCM calculates the desired line pressure based upon inputs from the transmission and engine. The TCM cal-
culates the torque input to the transmission and uses that information as the primary input to the calculation. The
line pressure is set to a predetermined value during shifts and when the transmission is in the PARK and NEUTRAL
positions. This is done to ensure consistent shift quality. During all other operation, the actual line pressure is com-
pared to the desired line pressure and adjustments are made to the pressurecontrol solenoid duty cycle.
REMOVAL
1. Remove the valve body from the transmission.
(Refer to 21 - TRANSMISSION/TRANSAXLE/AU-
TOMATIC - 42RLE/VALVE BODY - REMOVAL)
2. Remove the electrical connectors from the pres-
sure control solenoid (1) and the line pressure sen-
sor (2).
3. Remove the screws (6) holding the pressure con-
trol solenoid (1) and line pressure sensor (2) to the
valve body.
4. Remove the pressure control solenoid and line
pressure sensor from the valve body.
