Diagnostic Test

WARNING: This page is about a different car, the 2013 RAM 3500 HD and 2013 RAM 2500 HD. However, it is still accessible from the selected car via links, so may be relevant.

OTHER DTCS PRESENT
1. With the scan tool, check for transmission DTCs.
  Are any Pressure Switch Sense circuit DTCs present?
  
  Yes
  - Refer to DIAGNOSIS AND TESTING 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 about 1000 rpm on the Output Speed sensor then use the AutoStick® (ERS) and select 3rd gear. 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 allowing the vehicle to coast down to 650 to 550 rpm on the Output Speed sensor then apply the throttle between 40 and 50 Degrees.
  NOTE:
  Do not exceed 54 Degrees of Throttle Angle.
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.
  - 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 in accordance with the service information. With the scan tool, perform a Quick Learn.
  - 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.
  - 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. Accelerate lightly to 80 Km/h or 50 mph then brake lightly to a stop. Turn off the engine.
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 the PCM in accordance with the Service Information. With the scan tool, perform a Quick Learn.
  - Perform the TRANSMISSION VERIFICATION TEST. Refer to STANDARD PROCEDURE .
  No
  - Test Complete.
