What transmission does the Cayenne use?

ZF is the transmission brand for the Cayenne. ZF, also known as ZF Friedrichshafen, is a German transmission manufacturer. Alongside Aisin and Getrag, it is recognized as one of the world's top three transmission suppliers. Headquartered in Germany, ZF's main products include mechanical transmissions, hydraulic automatic transmissions, various gearboxes, as well as steering systems, drive axles, pumps, suspension systems, and electromagnetic clutchers. The Cayenne is equipped with an 8-speed automatic transmission (8AT). The AT transmission is a common type of automatic transmission with a relatively complex structure, featuring multiple planetary gearsets and clutch plates. The 8-speed automatic transmission incorporates four gear sets with only five shifting elements, engaging just two elements during each shift. Additionally, the new axial-parallel sliding vane pump enhances transmission efficiency, minimizing energy loss. For daily use of the Cayenne's transmission, the following points should be noted: Do not delay transmission fluid changes for extended periods. While many modern vehicles feature 'maintenance-free' transmission fluid, this does not mean it never needs replacement. Prolonged neglect can damage internal components such as bearings and the transmission housing. Avoid coasting in neutral for long durations. While 'experienced drivers' may coast in neutral with manual transmissions, doing so in an automatic can cause overheating and abrupt engagement when shifting back to Drive (D). Never shift into Drive (D) or Reverse (R) before the vehicle comes to a complete stop. Some drivers attempt smooth gear changes by shifting into reverse while still moving forward, which can severely damage transmission gears and lead to grinding or failure over time. Avoid frequently climbing steep slopes in Drive (D). Under heavy load, automatic transmissions may overheat or upshift prematurely, reducing climbing power. In such cases, use manual mode to lock in lower gears or engage sport mode to protect the transmission. Do not tow the vehicle long distances. If the Cayenne requires towing due to a breakdown, use a flatbed trailer with the transmission in Neutral (N). Never tow it with a rope or similar method, as this can damage the transmission.
I've been driving for over a decade and have experienced everything from older to newer Cayenne models. The earliest ones used a 6-speed Tiptronic automatic transmission, but now the entire lineup has been upgraded to the 8-speed Tiptronic S. The most noticeable difference when driving is the significant improvement in the smoothness of the new transmission; you can barely feel any jerking when crawling in traffic. At highway speeds, the engine RPM is kept lower, cruising at just 1800 RPM at 120km/h, which is particularly fuel-efficient. The shift response in manual mode is also much quicker than the old model; a quick flick of the paddle immediately downshifts. However, it's still different from the dual-clutch PDK in the 911—the PDK is more aggressive on the track, but this 8-speed automatic is more comfortable for daily driving. It's recommended to change the transmission fluid every 60,000 kilometers; neglecting this can lead to valve body sticking over time.
