2006 DODGE RAM SRT-10 sensor

FLUID LEVEL CHECK USING SCAN TOOL
NOTE: Engine and Transmission should be at normal operating temperature before performing this proce-
dure.
1. Start engine and apply parking brake.
2. Connect scan tool and select transmission.
3. Select sensors.
4. Read the transmission temperature value.
5. Compare the fluid temperature value with the chart.
6. Adjust transmission fluid level shown on the dipstick according to the 42RLE Fluid Temperature Chart. Use only
Mopar
ATF+4, Automatic Transmission Fluid.
7. Check transmission for leaks.
FLUID/FILTER SERVICE
NOTE: Only fluids of the type labeled MoparATF+4, Automatic Transmission Fluid, should be used in the
transmission sump. A filter change should be made at the time of the transmission oil change. The magnet
(on the inside of the oil pan) should also be cleaned with a clean, dry cloth.
NOTE: If the transmission is disassembled for any reason, the fluid and filter should be changed.
1. Raise vehicle on a hoist. Place a drain container with a large opening, under transmission oil pan.

7. Remove any steering column (1) trim necessary to
access the gearshift cable (2) and BTSI mecha-
nism.
8. Disconnect the BTSI wiring connector (5).
9. Disconnect cable at lower column bracket and shift
lever pin and pull the cable through the dash panel
opening into the vehicle.
10. Remove gearshift cable (2) from vehicle.
INSTALLATION
1. Route the transmission end of the gearshift cable
(1) through the opening in the dash panel.
2. Seat the cable grommet (2) into the dash panel
opening.
3. Snap the cable into the steering column (1) bracket
so the retaining ears are engaged and snap the
cable eyelet onto the shift lever ball stud.
4. Raise the vehicle.
5. Place the transmission manual shift lever in the
“PARK” detent (rearmost) position and rotate prop
shaft to ensure transmission is in PARK.
6. Route the gearshift cable through the transmission
mounting bracket and secure the cable by snap-
ping the cable retaining ears into the transmission
bracket and snapping the cable eyelet on the man-
ual shift lever ball stud.
7. Lower vehicle.
8. Lock the shift cable adjustment by pressing the
cable adjuster lock tab (3) downward until it snaps
into place.
9. Check for proper operation of the transmission range sensor.
10. Adjust the gearshift cable (Refer to 21 - TRANSMISSION/AUTOMATIC/GEAR SHIFT CABLE - ADJUST-
MENTS) and BTSI mechanism (Refer to 21 - TRANSMISSION/AUTOMATIC/BRAKE TRANSMISSION SHIFT
INTERLOCK SYSTEM - ADJUSTMENTS) as necessary.

ADJUSTMENTS - GEARSHIFT CABLE
Check adjustment by starting the engine in PARK and NEUTRAL. Adjustment isCORRECT if the engine starts only
in these positions. Adjustment is INCORRECT if the engine starts in one butnot both positions. If the engine starts
in any position other than PARK or NEUTRAL, or if the engine will not start atall, the transmission range sensor
may be faulty.
Gearshift Adjustment Procedure
1. Shift transmission into PARK.
2. Release cable adjuster lock tab (3) (underneath the
steering column) to unlock cable.
3. Raise vehicle.
4. Disengage the cable eyelet from the transmission
manual shift lever.
5. Verify transmission shift lever is in PARK detent by
moving lever fully rearward. Last rearward detent is
PARK position.
6. Verify positive engagement of transmission park
lock by attempting to rotate propeller shaft. Shaft
will not rotate when park lock is engaged.
7. Snap the cable eyelet onto the transmission man-
ual shift lever.
8. Lower vehicle.
9. Lock shift cable by pressing cable adjuster lock tab (3) downward until it snaps into place.
10. Check engine starting. Engine should start only in PARK and NEUTRAL.

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.

INSTALLATION
1. Install the pressure control solenoid (1) and line
pressure sensor (2) into the valve body.
2. Install the screws (6) to hold the pressure control
solenoid (1) and line pressure sensor (2) to the
valve body.
3. Install the electrical connectors to the pressure
control solenoid (1) and the line pressure sensor
(2).
4. Install the valve body into the transmission. (Refer
