What brand is the Jaguar 8AT transmission?
1 Answers
The Jaguar 8AT transmission belongs to the German ZF brand. ZF Friedrichshafen AG, headquartered in Friedrichshafen, Germany, is a Fortune Global 500 company and a global partner and component supplier in the automotive industry, specializing in providing automotive components such as transmissions, steering systems, and chassis systems. Jaguar uses an 8-speed automatic manual transmission, which is the 8AT transmission. The AT transmission is a relatively common automatic transmission. The structure of the AT transmission is quite complex, containing many planetary gears and clutch plates inside. The 8-speed automatic manual transmission features four gear sets with only five shifting elements. During each shift, only two elements are engaged. Additionally, the newly designed axial-parallel sliding vane pump enhances transmission efficiency, minimizing energy loss. When using the Jaguar 8AT transmission in daily driving, the following points should be noted: Do not delay changing the transmission oil for extended periods. Although many modern vehicles feature maintenance-free transmission oil, "maintenance-free" does not mean "never change." Prolonged failure to replace the transmission oil can damage internal components such as bearings and the housing. Avoid coasting in neutral for long durations. While driving manual transmission vehicles, many experienced drivers may coast in neutral, but for automatic transmission vehicles, this can cause the transmission to overheat and produce a noticeable jolt when shifting back into D (Drive) mode. Never shift into D/R (Drive/Reverse) before the vehicle comes to a complete stop. Many drivers, aiming to demonstrate "smooth" operation, shift directly into reverse while the vehicle is still moving, which can severely damage the transmission gears and lead to gear grinding faults over time. Avoid frequently climbing steep slopes in D mode. When tackling steep inclines, automatic transmission vehicles often overheat due to high loads or prematurely upshift, resulting in insufficient climbing power. In such cases, use manual mode to lock in lower gears or switch to sport mode to protect the transmission. Do not tow the vehicle over long distances. If an automatic transmission vehicle breaks down, it should be transported using a flatbed tow truck, with the vehicle in N (Neutral) mode when moving onto the tow bed. Avoid using tow ropes or dragging the vehicle directly.
