Description:

This error code is stored when the CC or DC clutches slip beyond the limit established by the service code. The PTP control unit downshifts the transmission to protect the system from damage due to prolonged clutch slipping.

Reaction:

The control unit limits functionality by downshifting the transmission to reduce load on the slipping clutches.

Recommendations:

• Inspect Clutches:
  Check the C Clutch (CC) and D Clutch (DC) for signs of wear or damage. Replace if necessary.
• Verify Hydraulic Pressure:
  Ensure that the hydraulic pressure is within the specified range to allow proper clutch engagement.
• Test Clutch Engagement:
  Perform diagnostic tests to verify that the clutches engage and disengage correctly without slipping.
• Check Transmission Fluid:
  Ensure the transmission fluid is at the correct level and in good condition. Replace if necessary.
• Consult Technical Support:
  If the issue persists, consult technical support or the manufacturer for further assistance.

Note:

Maintaining the proper function of the clutches and the hydraulic system is essential for reliable transmission operation. Regular inspections and prompt repairs can help prevent related issues.
