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.
42RLE Fluid Temperature Chart
NOTE: One of the oil pan bolts (5) has a sealing
patch applied from the factory. Separate this bolt
for reuse.
2. Loosen pan bolts and tap the pan at one corner to
break it loose allowing fluid to drain, then remove
the oil pan.
3. Install a new filter and o-ring on bottom of the valve
body and tighten retaining screws to 5 Nꞏm (45 in.
lbs.).
NOTE: Before installing the oil pan bolt (5) in the
bolt hole located between the torque converter
clutch on and U/D clutch pressure tap circuits, it
will be necessary to replentish the sealing patch
on the bolt using Mopar
Lock & Seal Adhesive.
4. Clean the oil pan and magnet. Reinstall pan using
new Mopar
Silicone Adhesive sealant. Tighten oil
pan bolts to 20 Nꞏm (14.5 ft. lbs.).
5. Pour four quarts of Mopar
AT F + 4 , A u t o m a t i c
Transmission Fluid, through the dipstick opening.
6. Start engine and allow to idle for at least one minute. Then, with parkingand service brakes applied, move selec-
tor lever momentarily to each position, ending in the park or neutral position.
7. Check the transmission fluid level and add an appropriate amount to bring the transmission fluid level to 3mm
(1/8 in.) below the lowest mark on the dipstick.
8. Recheck the fluid level after the transmission has reached normal operating temperature, 82° C (180°F).
9. To prevent dirt from entering transmission, make certain that dipstickis fully seated into the dipstick opening.
TRANSMISSION FILL
To avoid overfilling transmission after a fluid change or overhaul, perform the following procedure:
1. Remove dipstick and insert clean funnel in transmission fill tube.
2. Add following initial quantity of Mopar
ATF+4totransmission:
a. If only fluid and filter were changed, add3 pints (1-1/2 quarts)of ATF +4 to transmission.
b. If transmission was completely overhauled, torque converter was replaced or drained, and cooler was
flushed, add12 pints (6 quarts)of ATF +4 to transmission.
3. Apply parking brakes.
4. Start and run engine at normal curb idle speed.
5. Apply service brakes, shift transmission through all gear ranges then back to NEUTRAL, set parking brake, and
leave engine running at curb idle speed.
6. Remove funnel, insert dipstick andcheck fluid level. If level is low,add fluid to bring level to MIN mark on
dipstick.Check to see if the oil level is equal on both sides of the dipstick. If one side is noticably higher than
the other, the dipstick has picked up some oil from the dipstick tube. Allowthe oil to drain down the dipstick tube
and re-check.
7. Drive vehicle until transmission fluid is at normal operating temperature.
8. With the engine running at curb idle speed, the gear selector in NEUTRAL,and the parking brake applied, check
the transmission fluid level.
CAUTION: Do not overfill transmission, fluid foaming and shifting problems can result.
9. Add fluid to bring level up to MAX arrow mark.
When fluid level is correct, shut engine off, release park brake, remove funnel, and install dipstick in fill tube.

In either case, air bubbles can cause overheating and/or fluid oxidation,and varnishing. This can interfere with nor-
mal valve, clutch, and accumulator operation. Foaming can also result in fluid escaping from the transmission vent
where it may be mistaken for a leak.
After the fluid has been checked, seat the dipstick fully to seal out water and dirt.
The transmission has a dipstick to check oil level. It is located on the right side of the engine. Be sure to wipe all
dirt from dipstick handle before removing.
The torque converter fills in both the P(PARK) and N (NEUTRAL) positions. Place the selector lever in P (PARK)
to be sure that the fluid level check is accurate.The engine should be running at idle speed for at least one
minute, with the vehicle on level ground.At normal operating temperature (approximately 82° C. or 180° F), the
fluid level is correct if it is in the HOT region (cross-hatched area) on theoil level indicator. The fluid level will be
approximately at the upper COLD hole of the dipstick at 21° C (70° F) fluid temperature.
NOTE: Engine and Transmission should be at normal operating temperature before performing this proce-
dure.
1. Start engine and apply parking brake.
2. Shift the transmission into DRIVE for approximately 2 seconds.
3. Shift the transmission into REVERSE for approximately 2 seconds.
4. Shift the transmission into PARK.
5. Hook up scan tool andselect transmission.
6. Select sensors.
7. Read the transmission temperature value.
8. Compare the fluid temperature value with the chart.
9. Adjust transmission fluid level shown on the dipstick according to the Transmission Fluid Temperature Chart.
NOTE: After adding any fluid to the transmission, wait a minimum of 2 minutes for the oil to fully drain from
the fill tube into the transmission before rechecking the fluid level.
10. Check transmission for leaks.
Theory of Operation
The Torque Converter Clutch (TCC) Solenoid is used to engage the TCC which improves fuel economy. The Over-
drive Solenoid is used to engage the gear change from third to Overdrive.
When Monitored:
Continuously with the ignition on and the engine running.
Set Condition:
This DTC will set if the expected engine RPM drop does not occur within 4 seconds of the gear change being
requested by the PCM three consecutive failed tests.
Possible Causes
FLUID LEVEL AND CONDITION - EXCESSIVE DEBRIS OR BURNT
3-4 SHIFT SOLENOID
INTERNAL TRANSMISSION FAILURE
Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 21 - TRANSMIS-
SION/TRANSAXLE/AUTOMATIC - 48RE - STANDARD PROCEDURE)
Diagnostic Test
1.CHECK IF THERE ANY TRANSMISSION CONTROL DTCS PRESENT
Ignition on, engine not running.
With the scan tool, read Engine DTCs.
Are there any TIPM TCM Power Control Circuit DTCs also present?
Ye s>>
Refer to the Transmission or Engine category and perform the appropriate symptom(s).
No>>
Go To 2
2.CHECK IF THE DTC IS CURRENT
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?
Ye s>>
Go To 3
No>>
Go To 6
3.CHECK THE GOVERNOR AND OVERDRIVE PRESSURE
Turn the ignition off to the lock position.
Connect a 0 - 2068 KPa (0 - 300 PSI) pressure gauge to the Overdrive Clutch test port.
Connect another 0 - 2068 KPa (0 - 300 PSI) pressure gauge to the Governor Pressure test port. (Refer to 21 -
TRANSMISSION/TRANSAXLE/AUTOMATIC - 48RE - DIAGNOSIS AND TESTING)
Start the engine and allow the transmission temperature to rise to normal operating temperature.
CAUTION: Apply the parking brake.
Firmly apply the brakesand place the gear selector in Drive.
While observing the pressure gauges, with the scan tool, select 4th gear from the Gov and 3-4 Shift Valve Test.
