light DODGE RAM SRT-10 2006 Service Repair Manual

P0602-CONTROL MODULE PROGRAMMING ERROR/NOT PROGRAMMED
For a complete wiring diagramRefer to Section 8W.
When Monitored:
Check for generic software is made at power-up.
Set Condition:
If generic software is found, the MIL will light immediately. This DTC is designed to signal the technician that
the controller still has generic software installed.
Possible Causes
PCM - PROGRAMMING ERROR
Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 21 - TRANSMIS-
SION/TRANSAXLE/AUTOMATIC - 42RLE - STANDARD PROCEDURE)
Theory of Operation
The controller is programmed during manufacturing with generic softwareto facilitate testing. This software does not
have the proper calibrations to control a transmission in a vehicle. The check for generic software is made at power-
up. If generic software is found, the MIL will light immediately and the MILwill stay on even if the fault is cleared,
until the proper software is installed.Note:Transmissionwillbeplacedin limp-in mode.
Diagnostic Test
1.CONTROL MODULE PROGRAMMING ERROR
NOTE: Controller is programmed with generic software and will not allow the correct vehicle Powertrain
management.
Record the controller part number.

CLUTCH AIR PRESSURE TESTS
Inoperative clutches can be located by substituting air
pressure for fluid pressure. The clutches may be
tested by applying air pressure to their respective pas-
sages after the valve body has been removed. Use
Plate Set 6599-1 (1) and 6599-2 (1) to perform test.
To make air pressure tests, proceed as follows:
NOTE: The compressed air supply must be free of
all dirt and moisture. Use a pressure of 30 psi.
1. Remove oil pan and valve body. (Refer to 21 -
TRANSMISSION/AUTOMATIC - 42RLE/VALVE
BODY - REMOVAL)
2. Apply air pressure to the holes in the plates (1),
one at a time.
3. Listen for the clutch to apply. It will give a slight
thud sound. If a large amount of air is heard escap-
ing, the transmission must be removed from vehi-
cle, disassembled and all seals inspected.
2/4 CLUTCH
Apply air pressure to the feed hole located on the 2/4 clutch retainer (2). Look in the area where the 2/4 piston
contacts the first separator plate and watch carefully for the 2/4 piston tomoverearward.Thepistonshouldreturn
to its original position after the air pressure is removed.

16. Remove the starter motor.
17. Remove the engine to transmission collar.
18. Rotate crankshaft in clockwise direction until con-
verter bolts are accessible. Then remove bolts
one at a time. Rotate crankshaft with socket
wrench on dampener bolt.
19. Disconnect the transmission vent hose from the
transmission.
20. Remove transfer case. (Refer to 21 - TRANSMIS-
SION/TRANSFER CASE - REMOVAL)
21. Support rear of engine with safety stand or jack.
22. Raise transmission slightly with service jack to
relieve load on crossmember and supports.
23. Remove bolts securing rear support and cushion
to transmission and crossmember.
24. Remove bolts attaching crossmember to frame
and remove crossmember.
25. Disconnect transmission fluid cooler lines (1) at
transmission fittings (3) and clips (2).
26. Remove all remaining converter housing bolts.
27. Carefully work transmission and torque converter
assembly rearward off engine block dowels.
28. Hold torque converter in place during transmission
removal.
29. Lower transmission and remove assembly from
under the vehicle.
30. To remove torque converter, carefully slide torque
converter out of the transmission.
DISASSEMBLY
NOTE: If the transmission is being reconditioned (clutch/seal replacement) or replaced, it is necessary to
perform the Quick Learn Procedure using the scan tool (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL
MODULES/TRANSMISSION CONTROL MODULE - STANDARD PROCEDURE).
NOTE: Tag all clutch pack assemblies, as they are removed, for reassembly identification.
CAUTION: Do not intermix clutch discs or plates as the unit might then fail.
Before disassembling transmission, move the shift lever clockwise as faras it will go and then remove the shift
lever.
