Diagnostic Test

WARNING: This page is about a different car, the 2013 RAM 1500. However, it is still accessible from the selected car via links, so may be relevant.

OTHER DTCS PRESENT
1. With the scan tool, read DTCs.
  Are any Pressure Switch Sense circuit DTCs present?
  
  Yes
  - Refer to the DIAGNOSTIC CODE INDEX and perform the appropriate diagnostic procedure.
  No
  - Go To 2
CHECK 2C CLUTCH VOLUME INDEX
1. With the scan tool, erase Transmission DTCs.
2. Drive the vehicle at 80 Km/h (50 mph), then depress the OD off button. This will put the vehicle into third gear.
  NOTE:
  The TRANS TEMP DEG must be at least 43° C (110° F) before performing the following steps.
3. Perform at least ten 3-2 kickdowns by applying the throttle between 10 and 54 TPS Degrees at speeds of about 80 Km/h (50 mph).
4. With the scan tool, read the 2C CL VOL INDEX.
  Is the 2C CL VOL INDEX below 10?
  
  Yes
  - Go To 3
  No
  - Go To 5
2C CLUTCH CIRCUIT LEAKS IN THE VALVE BODY
1. Turn the ignition OFF.
2. Remove the transmission oil pan in accordance with the Service Information.
3. Remove the valve body in accordance with the Service Information.
4. Check condition of the 2C accumulator springs.
5. Look for possible leak paths into the 2C clutch hydraulics circuit within the valve body.
  Were any problems found?
  
  Yes
  - Repair as necessary. Refer to VALVE BODY, REMOVAL .
  - Perform the TRANSMISSION VERIFICATION TEST. Refer to STANDARD PROCEDURE .
  No
  - Go To 4
AIR CHECK 2C CLUTCH CIRCUIT
1. Turn the ignition OFF.
2. Perform an air check on the 2C Clutch circuit in accordance with the Service Information.
3. Watch and listen for 2C Clutch piston movement.
  Dose the piston stroke and return properly?
  
  Yes
  - Replace the Transmission/TRS Solenoid Assembly per the service information. With the scan tool, perform a Quick Learn. Refer to ASSEMBLY, TRANSMISSION SOLENOID AND TRS, REMOVAL .
  - Perform the TRANSMISSION VERIFICATION TEST. Refer to STANDARD PROCEDURE .
  No
  - Repair internal transmission as necessary. Pay attention to the components related to the 2C clutch. A broken or dislodged 2C return spring, snap ring or broken 2C Accumulator Spring could cause this problem. Refer to REMOVAL .
  - Perform the TRANSMISSION VERIFICATION TEST. Refer to STANDARD PROCEDURE .
VERIFY PCM OPERATION
NOTE:
The TRANS TEMP DEG must be at least 43° C or 110° F before performing the following steps.
1. Perform eight learnable starts. A learnable start is defined as follows: Start the engine and accelerate lightly to 80 Km/h or 50 mph, then brake lightly to a stop. Turn the engine off.
2. With the scan tool, record the CL VOL INDEX (CVI) for all clutches
3. With the scan tool, perform a BATTERY DISCONNECT.
4. With the scan tool, read the CVIs and compare them to the readings recorded before the BATTERY DISCONNECT.
  Are any of the CVIs less than 5 or different than before the BATTERY DISCONNECT?
  
  Yes
  - Using the schematics as a guide, check the Powertrain Control Module (PCM) terminals for corrosion, damage or terminal push out. Pay particular attention to all power and ground circuits. If no problems are found, replace and program the PCM in accordance with the Service Information. With the scan tool, perform a Quick Learn. Refer to MODULE, POWERTRAIN CONTROL, REMOVAL .
  - Perform the TRANSMISSION VERIFICATION TEST. Refer to STANDARD PROCEDURE .
  No
  - Test Complete.
