The Jeep Grand Cherokee uses an automatic transmission, specifically an eight-speed automatic in the latest models.
Across its generations, Jeep has relied on automatic gearboxes rather than a manual. In the current WL generation, the Grand Cherokee pairs an eight-speed automatic with most powertrains, including V6, V8, and EcoDiesel in some markets. The eight-speed unit is part of Chrysler’s TorqueFlite family and is aligned with the ZF 8HP design, optimized for both on-road efficiency and off-road capability. Exact model-year naming and calibration can vary by region.
Current generation transmission
For the modern Grand Cherokee (the WL generation launched in 2021, and the related Grand Cherokee L three-row model), Jeep uses an eight-speed automatic transmission across most powertrains. The gearbox in these models is the TorqueFlite 8-speed automatic, a design associated with ZF’s 8HP family, tuned for smooth shifts, towing capability, and fuel efficiency.
Performance and efficiency considerations
Having eight speeds helps keep the engine in its optimal power range for acceleration and cruising, while also providing ratios that support better highway fuel economy and confident low-speed capability for off-road use.
Historical context and variations by year
Earlier Grand Cherokee generations used automatic transmissions with fewer gears, and there was no manual transmission option offered in production models. Transmission availability and exact gear counts varied by year and engine, with a progression from fewer speeds to eight in later generations.
Summary
In short: modern Jeep Grand Cherokees use an eight-speed automatic transmission, part of the TorqueFlite family (based on the ZF 8HP design). The model’s gear count has increased over time, and older generations used automatic gearboxes with fewer speeds.
