What This Product Does:

  • Feeds coolant into the PDK gearbox cooling circuit
  • Helps dissipate heat generated by the transmission
  • Maintains stable gearbox operating temperatures
  • Protects internal transmission components from heat-related wear
  • Supports smooth shifting and consistent performance

Symptoms Of Wear Or Failure:
  • Coolant leaks near the transmission or under the vehicle
  • Low coolant warning light
  • Frequent coolant top-offs
  • Transmission temperature warning message
  • Gearbox running hotter than normal
  • Transmission performance issues or limp mode activation
  • Coolant residue or staining around hose fittings
  • Cracks, brittleness, swelling, or soft spots in the hose material
  • Steam from beneath the vehicle in severe cases

Why Replacement Matters:
  • Replacing a worn PDK gearbox coolant feed hose is important because it ensures coolant is properly delivered to the transmission cooling system. Over time, heat and pressure can cause the hose to weaken, crack, or leak, reducing coolant flow to the gearbox cooler.
  • If the hose fails, the transmission may overheat, triggering warning messages, reduced performance, or limp mode. Continued overheating can lead to premature wear and costly internal gearbox damage.
  • Installing a new feed hose helps prevent coolant loss, restores proper cooling circulation, and protects the PDK transmission for long-term reliability and performance.
