Gearbox oil cooler ATF. Porsche 958 (92A) Cayenne 2011-18  ❭  95830703700

Gearbox oil cooler ATF.
The gearbox oil cooler plays a critical role in regulating the temperature of automatic transmission fluid (ATF). As the Tiptronic transmission operates - especially during towing, spirited driving, hill climbs, or hot ambient conditions - ATF can heat up significantly. This cooler transfers excess heat from the transmission fluid into the engine’s cooling circuit or air stream, helping maintain the proper fluid temperature range.

Fits:
Cars with 8-speed Automatic gearbox for all-wheel drive (option code: G1G)
Porsche 958 (92A) Cayenne 3.6L 2011 - 2018
Porsche 958 (92A) Cayenne 3.0L / 4.2L Diesel 2011 - 2018
Porsche 958 (92A) Cayenne 3.0L HYBRID 2011 - 2014
Porsche 958 (92A) Cayenne 4.8L 2011 - 2018

By keeping the ATF within its ideal thermal window, the oil cooler helps:
• Preserve transmission lubrication properties
•  Reduce wear on internal gearbox components
•  Improve shift consistency and responsiveness
•  Extend the life of seals, clutches, and bearings
•  Prevent overheating-related transmission faults

Without an effective cooler, high ATF temperatures can degrade fluid performance and accelerate transmission wear or failure.

Fitment / Position on Car
•  Installed on: Front engine bay, integrated into or adjacent to the cooling network
•  Location: Connected via dedicated ATF coolant lines to engine cooling circuit or external coolers
•  Integration: Interfaces with radiator, thermostat, transmission lines and pump circulation routing

High transmission fluid temperatures can lead to degraded lubrication, increased wear, clutch slippage, and premature failure. The gearbox oil cooler mitigates this risk by maintaining fluid temperatures in the proper range - especially during demanding driving. Using a Genuine Porsche OE gearbox oil cooler ensures the correct heat rejection rate, plumbing interfaces, and robust construction that match Porsche’s factory design - helping extend the life and performance of your Tiptronic transmission.
