bolts to hold valve body in place.
7. Tighten valve body bolts alternately and evenly to
12 Nꞏm (105 in. lbs.) torque.
CAUTION: The primary oil filter seal MUST be fully
installed flush against the oil pump body. DO NOT
install the seal onto the filter neck and attempt to
install the filter and seal as an assembly. Damage
to the transmission will result.
8. Install a new primary oil filter seal in the oil pump
inlet bore. Seat the seal in the bore with the butt
end of a hammer, or other suitable tool.
9. Place replacement filter (1) in position on valve
body and into the oil pump.
10. Install screw to hold filter to valve body. Tighten
screw to 4.5 Nꞏm (40 in. lbs.) torque.
11. Connect the solenoid and pressure switch assem-
bly connector.
12. Install oil pan. Tighten pan bolts to 12 Nꞏm (105 in. lbs.) torque.
13. Lower vehicle and fill transmission with Mopar
AT F + 4 .
14. Check and adjust gearshift cable, if necessary.

Theory of Operation
The Transmission Temperature Sensor is used to sense when the transmissiontemperatureistoohotortoocoldto
operate overdrive and/or the torque convertor clutch. When the transmission sensor detects a temperature below 0°
C (32° F), overdrive and the torque convertor clutch are disabled. When thedetected temperature is above 127° C
(260° F), overdrive is disabled and 3rd gear with TCC is engaged, this strategy is used to increase transmission
fluid flow to help cool the transmission.
When Monitored:
Continuously with the ignition on and the engine running.
Set Condition:
The DTC will set after two consecutive trips in which the transmission oil temperature is greater than 5° C (40°
F) and the transmission oil temperature does not rise more than 8° C (16° F) after 20 minutes of run time with
a vehicle speed greater than 48 Kmh (30 mph). The DTC will also set if the engine temperature is greater than
38° C (100° F) with the transmission oil temperature greater than 127° C (260° F).

Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 21 - TRANSMIS-
SION/TRANSAXLE/AUTOMATIC - 48RE - STANDARD PROCEDURE)
Diagnostic Test
1.CHECK IF THE DTC IS CURRENT
Ignition on, engine not running.
With the scan tool, read Engine DTCs.
Record the Freeze Frame data for the reported DTC.
With the scan tool, erase DTCs.
Turn the ignition off to the lock position.
Using the Freeze Frame data recorded earlier, try to duplicate the conditions in which the DTC originally set.
NOTE: It may be necessary to road test the vehicle to duplicate the originalset conditions.
With the scan tool, read Engine DTCs.
Did the DTC reset?

2.CHECK FOR OTHER TRANSMISSION DTCS
Does the scan tool show any Park/Neutral DTCs?
Ye s>>
Refer to the Transmission category and perform the appropriate symptom(s).
No>>

3.COMPARE THE TRANSMISSION TEMPERATURE TO ENGINE COOLANT TEMPERATURE
NOTE: To test the transmission temperature sensor, the engine and transmission temperature must be at or
below 29.4° C (85° F).
With the scan tool, read the Transmission and Engine temperatures.
Is the transmission temperature within 5° C (9° F) of the engine coolant temperature?
Ye s>>
Go To 4
No>>
Go To 5
4.CHECK IF THE TRANSMISSION TEMPERATURE INCREASES 15 DEGREES OVER 10 MINUTEPERIOD
NOTE: To test the transmission temperature sensor, the engine and transmission temperature must be at or
below 29.4° C (85° F).
CAUTION: Apply the parking brake.
Start the engine, firmly apply the brakes and allow the engine to idle in Drive.
With the scan tool, monitor the Transmission Temperature.
NOTE: If the transmission temperature sensor is working properly, the transmission temperature should rise
at least 8° C (15° F) within a ten minute period.
Did the transmission temperature increase at a steady rate and rise at least 8° C (15° F) over a 10
minute period?
Ye s>>
Go To 6
No>>
