PTI 000127.01 – Transmission Enable Pressure Very Low

PTI 000127.01 (PTI 127.01)

Code: 000127.01

Shortcode: 127.01


This error code is triggered when the transmission enable pressure drops below 1000 kPa (10 bar) or 145 psi while the engine is running and the oil temperature is above 20°C (68°F).


When this code is detected, the control unit commands the equipment to enter Park mode, which is recoverable.


  • Check Transmission Pressure:
    • Inspect the transmission system to ensure the pressure is above the specified threshold.
    • Check for any leaks or obstructions in the transmission lines.
  • Inspect Oil Levels and Quality:
    • Verify that the transmission oil level is correct and the oil quality is within specifications.
    • Replace oil if it is degraded or contaminated.
  • Evaluate Transmission Pump:
    • Ensure that the transmission pump is functioning properly.
    • Check for any signs of wear or damage that could affect pressure.
  • Monitor Temperature:
    • Ensure the engine and transmission temperatures are within operating ranges.


Consistently low transmission enable pressure can lead to serious damage. Regular maintenance and monitoring of pressure levels are essential to avoid long-term issues.
