Chrysler 300/300 Touring/300C, Dodge Magnum. Manual — part 2067
SEAL-OUTPUT SHAFT
REMOVAL
1. Remove the propeller shaft (Refer to 3 - DIFFERENTIAL & DRIVELINE/PROPELLER SHAFT/PROPELLER
SHAFT - REMOVAL). Move propeller shaft to the right and tie up.
2. Verify that the transmission is in PARK in order to prepare for the removal of the output shaft nut.
3. Remove the nut holding the propeller shaft flange to the output shaft and remove the flange.
4. Remove the output shaft seal with suitable screw and slide hammer.
INSTALLATION
1. Position the new output shaft seal over the output
shaft and against the transmission case.
2. Use Seal Installer 8902A (1) to install the seal.
3. Verify that the transmission is in PARK in order to
prepare for the installation of the output shaft nut.
4. Install the propeller shaft flange onto the output
shaft and install an new flange nut. Tighten the
flange nut to 120 N·m (88.5 ft.lbs.).
5. Stake the output shaft nut to the output shaft as
follows.Place the Staking Tool 9078 (2) and Driver
Handle C-4171 onto the output shaft.
6. Rotate the Staking Tool 9078 (2) until the alignment
pin (3) engages the output shaft notch (4).

7. Press downward on the staking tool until the stak-
ing pin (3) contacts the output shaft nut flange (2).
8. Strike the Driver handle C-4171 with a suitable
hammer until the output shaft nut is securely
staked to the output shaft.
9. Install the propeller shaft (Refer to 3 - DIFFEREN-
TIAL &
DRIVELINE/PROPELLER
SHAFT/PRO-
PELLER SHAFT - INSTALLATION).

SENSOR-OUTPUT 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, though its coil is excited by rotation of the
rear planetary carrier lugs. The TCM interprets this information as output shaft rpm.
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 output
speed sensor (2).
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 output speed sensor
(2) to the transmission case.
5. Remove the output speed sensor (2) from the
transmission case.

INSTALLATION
1. Install the output speed sensor (2) into the trans-
mission case.
NOTE: Before installing the speed sensor bolt, it
will be necessary to replentish the sealing patch
on the bolt using Mopar
T
Lock & Seal Adhesive.
2. Install the bolt to hold the output speed sensor (2)
into the transmission case. Tighten the bolt to 9
N·m (80 in.lbs.).
3. Install the wiring connector onto the output speed
sensor (2).
4. Verify the transmission fluid level. Add fluid as nec-
essary. (Refer to 21 - TRANSMISSION/AUTO-
MATIC
TRANSMISSION

STANDARD PROCEDURE)
5. Lower vehicle.
