The typical total is about 9 to 11 quarts of automatic transmission fluid, with the exact amount depending on the transmission type and whether you’re performing a simple drain-and-fill or a full service.
In 2012, the Grand Cherokee offered more than one automatic transmission option, which affects capacity. The precise amount depends on the specific transmission model and the service performed. The guide below outlines common figures and best practices for servicing).
Transmission options available in the 2012 Grand Cherokee
Here are the main automatic transmissions used in the 2012 Grand Cherokee and how they influence capacity.
- 5‑speed automatic transmission (older generation used in early WK2 models)
- 8‑speed automatic transmission (newer generation used on most 2012 models and later)
The exact fluid capacity depends on the specific transmission model and service performed. Always verify with your VIN and service manual for precise figures.
Estimated transmission fluid capacity by service type
Use these ranges as a guide when planning a maintenance service. A drain-and-fill is lighter on fluid than a full professional service that also replaces the filter and possibly flushes lines.
- Pann drain and fill (no additional services beyond replacing the pan fluid and filter): about 9 quarts (roughly 8.5 liters)
- Full service including pan drain, filter replacement, and any required line/torque converter flushing: about 11 quarts (roughly 10.5 liters)
These values are approximate and can vary by exact transmission model, the presence of a cooler line flush, and whether the torque converter was emptied.
How to check and fill transmission fluid safely
Follow a proper procedure to avoid overfilling or underfilling, and always use the correct fluid type as specified for your transmission. Note that some newer Jeep transmissions are "sealed" and may require a service at a shop rather than a DIY dipstick check.
- Warm up the vehicle to operating temperature and park on a level surface with the engine running (or as specified by the service manual).
- Check whether your transmission has a dipstick; if so, check level per the manual with the engine idling or running in park, after a brief interval.
- Drain fluid from the pan if performing a drain-and-fill, replace the filter if equipped, and reinstall the pan with the proper gasket.
- Refill gradually with the recommended ATF, then recheck the level and top off to the correct range as specified.
Always follow the vehicle's service manual or a qualified technician's instructions for accurate refill amounts and procedures.
Where to find the exact capacity for your specific Jeep Grand Cherokee
Check the owner's manual, the factory service manual for your VIN, or consult a Jeep dealer or trusted mechanic. Values can vary by engine, transmission code, and production date within the 2012 model year.
Summary
For a 2012 Jeep Grand Cherokee, plan on about 9 to 11 quarts of transmission fluid, with the exact figure depending on the installed transmission and whether you’re doing a simple drain-and-fill or a full-service job. Confirm the precise capacity for your VIN using the owner's manual or a service professional, especially if your vehicle has a specific transmission variant or you’re performing a more extensive service.
