Diagram ref no 1.

The gearbox oil cooler, also known as an ATF cooler or transmission oil heat exchanger, forms part of the Tiptronic transmission cooling system. It transfers heat away from the automatic transmission fluid to help maintain the correct operating temperature during normal driving.

What this part does 
  • Cools the Tiptronic automatic transmission fluid
  • Helps maintain stable gearbox oil temperatures
  • Supports smooth and consistent transmission operation
  • Helps protect internal transmission components from excessive heat
  • Supports correct ATF operating conditions
  • Replaces leaking, blocked or inefficient gearbox oil coolers 
  • Suitable for Tiptronic transmission servicing and repair
  • OE Match replacement for the original Porsche-style component.

Why Replace This Part?
The gearbox oil cooler can deteriorate due to age, corrosion, internal contamination or repeated heating and cooling cycles. Reduced cooling efficiency may allow transmission fluid temperatures to rise, while physical damage can result in fluid or coolant leakage depending on the system design. Replacing a faulty cooler helps restore effective transmission temperature control.

When to Replace This Part
  • Gearbox oil temperatures are higher than normal
  • ATF cooler is leaking
  • Cooler is blocked or internally contaminated
  • Transmission cooling system is being overhauled
  • Existing heat exchanger is corroded or damaged
  • Tiptronic transmission repair is being carried out.

Where it fits on the car
Fits within the Tiptronic automatic transmission oil cooling system.
