  Are any of the DTCs P0732, P0734 and/or P0846 present also?
  
  Yes
  - Replace the Transmission Solenoid/TRS Assembly in accordance with the Service Information. Refer to ASSEMBLY, TRANSMISSION SOLENOID AND PRESSURE SWITCH, REMOVAL .
  - Perform the 62TE TRANSMISSION VERIFICATION TEST. Refer to 62TE TRANSMISSION VERIFICATION TEST .
  No
  - Go To 3
CHECK FOR CONTAMINATED FLUID
1. Check the transmission fluid for water or other contamination.
  Is the transmission fluid contaminated?
  
  Yes
  - Repair the cause of the transmission fluid contamination in accordance with the Service Information. Refer to FLUID, STANDARD PROCEDURE .
  No
  - Go To 4
CHECK IF DTC P0845 IS CURRENT
1. With the scan tool, read DTCs.
  Is the status Active or is the Starts Since Set counter 2 or less for this DTC?
  
  Yes
  - Go To 5
  No
  - Go To 10
PCM AND WIRING
1. Turn the ignition off to the lock position.
2. Remove the Starter Relay.
  CAUTION:
  Removal of the Starter Relay will prevent the vehicle from being started in gear.
  
  WARNING:
  The Starter Relay must be removed from the PDC. Failure to do so may result in possible serious or fatal injury.
  
  NOTE:
  Failure to remove the Starter Relay can cause a Transmission - No Response condition.
3. Install the Transmission Simulator (special tool #8333B, Simulator, Transmission) and the Electronic Transmission Adapter kit.
4. Ignition on, engine not running.
5. With the Transmission Simulator, turn the Pressure Switch selector switch to 2/4.
6. With the scan tool, monitor the 2/4 Pressure Switch state while pressing the Pressure Switch Test button on the Transmission Simulator.
7. Wiggle the wires leading to the PCM while pressing and holding the Pressure Switch Test button.
  Did the 2/4 Pressure Switch state change from open to closed when the test button was pressed, and remain closed while wiggling the wires?
  
  Yes
  - Disassemble and inspect the Valve Body in accordance with the Service Information. Refer to VALVE BODY, DISASSEMBLY . If no problems are found in the Valve Body, replace the Transmission Solenoid/TRS Assembly. Refer to ASSEMBLY, TRANSMISSION SOLENOID AND PRESSURE SWITCH, REMOVAL .
  - Perform the 62TE TRANSMISSION VERIFICATION TEST. Refer to 62TE TRANSMISSION VERIFICATION TEST .
  No
  - Go To 6
(T47) 2/4 PRESSURE SIGNAL CIRCUIT OPEN

1. Turn the ignition off to the lock position.
2. Disconnect the PCM C1 harness connector.
3. Disconnect the Transmission Solenoid/TRS Assembly harness connector.
4. Measure the resistance of the (T47) 2/4 Pressure Signal circuit between the appropriate terminal of the PCM C1 harness connector and the Transmission Solenoid/TRS Assembly harness connector.
  Is the resistance above 5.0 Ohms?
  
  Yes
  - Repair the (T47) 2/4 Pressure Signal circuit for an open.
  - Perform the 62TE TRANSMISSION VERIFICATION TEST. Refer to 62TE TRANSMISSION VERIFICATION TEST .
  No
  - Go To 7
(T47) 2/4 PRESSURE SIGNAL CIRCUIT SHORTED TO GROUND

1. Measure the resistance between ground and the (T47) 2/4 Pressure Signal circuit.
  Is the resistance below 5.0 Ohms?
  
  Yes
  - Repair the (T47) 2/4 Pressure Signal circuit for a short to ground.
  - Perform the 62TE TRANSMISSION VERIFICATION TEST. Refer to 62TE TRANSMISSION VERIFICATION TEST .
  No
  - Go To 8
(T47) 2/4 PRESSURE SIGNAL CIRCUIT SHORTED TO VOLTAGE

Courtesy of CHRYSLER GROUP, LLC
1. Remove the PCM/TCM relay and with a fused jumper wire, jumper the Transmission Control Output to B(+).
2. Ignition on, engine not running.
3. Measure the voltage of the (T47) 2/4 Pressure Signal circuit.
  Is the voltage above 0.5 of a volt?
  
  Yes
  - Repair the (T47) 2/4 Pressure Signal circuit for a short to voltage.
  - Perform the 62TE TRANSMISSION VERIFICATION TEST. Refer to 62TE TRANSMISSION VERIFICATION TEST .
  No
  - Go To 9
TRANSMISSION CONTROL OUTPUT CIRCUIT OPEN

Courtesy of CHRYSLER GROUP, LLC
1. With the jumper wire still in place and using a 12-volt test light connected to ground, check (T16) Transmission Control Output circuit in the Transmission Solenoid/TRS Assembly harness connector.
  NOTE:
  The test light must illuminate brightly. Compare the brightness to that of a direct connection to the battery.
  
  Does the test light illuminate brightly?
  
  Yes
  - Replace and program the Powertrain Control Module in accordance with the Service Information. Refer to MODULE, POWERTRAIN CONTROL, REMOVAL . With the scan tool perform Quick Learn.
  - Perform the 62TE TRANSMISSION VERIFICATION TEST. Refer to 62TE TRANSMISSION VERIFICATION TEST .
  No
  - Repair the Transmission Control Output circuit for an open or high resistance. If the fuse is open make sure to check for a short to ground.
  - Perform the 62TE TRANSMISSION VERIFICATION TEST. Refer to 62TE TRANSMISSION VERIFICATION TEST .
CHECK THE WIRING AND CONNECTORS
1. The conditions necessary to set the DTC are not present at this time.
2. Using the schematics as a guide, inspect the wiring and connectors specific to this circuit.
3. Wiggle the wires while checking for shorted and open circuits.
4. With the scan tool, check the Event Data to help identify the conditions in which the DTC was set.
  Were there any problems found?
  
  Yes
  - Repair as necessary.
  - Perform the 62TE TRANSMISSION VERIFICATION TEST. Refer to 62TE TRANSMISSION VERIFICATION TEST .
  No
  - Test Complete.
