The Jeep Grand Cherokee is one of the most versatile SUVs on the market, built for both rugged adventures and comfortable daily driving. To keep it running smoothly, regular transmission maintenance is essential. Using the correct transmission fluid type and capacity ensures smooth shifting, prevents overheating, and extends transmission life. This guide breaks down the transmission fluid capacity for Jeep Grand Cherokee models by year and transmission type, plus the recommended fluids you should use.
Quick Answer – Transmission Fluid Capacity by Year
- 1999–2004 (4-speed automatic 42RE / 545RFE): ~4–5 quarts (drain & fill), ~10–14 quarts (full overhaul) – ATF+4
- 2005–2010 (545RFE 5-speed automatic): ~5.5–7 quarts (drain & fill), ~14–16 quarts (full overhaul) – ATF+4
- 2011–2013 (5-speed WA580 automatic): ~5.5–6 quarts (drain & fill), ~8.5–9 quarts (dry fill) – ATF+4
- 2014–2020 (8-speed ZF 8HP automatic): ~4.5–5 quarts (drain & fill), ~8.5–9 quarts (full fill) – ZF Lifeguard 8 / Mopar 8&9 Speed ATF
- 2021–Present (8-speed ZF 8HP automatic): ~4.5–5 quarts (drain & fill), ~9 quarts (full fill) – Mopar 8&9 Speed ATF
Recommended Transmission Fluids
- Mopar ATF+4 Automatic Transmission Fluid – Required for all 4-speed and 5-speed Jeep Grand Cherokee transmissions.
- Mopar 8&9 Speed ATF – Required for Jeep Grand Cherokee models with the ZF 8-speed transmission.
- Ravenol ATF 8HP Fluid – A high-quality alternative to OEM fluid for ZF transmissions.
Why Transmission Fluid Capacity Matters
Adding the right amount of transmission fluid is crucial. Underfilling can cause slipping, overheating, and poor lubrication. Overfilling can lead to foaming, erratic shifting, and possible transmission damage. Always check the dipstick (on older models) or follow the electronic check procedure (on newer 8-speed models) after refilling.
DIY Transmission Fluid Change – Basic Steps
If you plan to change the transmission fluid yourself, here’s a simplified process:
- Warm up the engine and transmission for a few minutes.
- Raise the vehicle safely with jack stands or a lift.
- Place a drain pan under the transmission and remove the drain plug.
- Let the fluid drain fully, then reinstall the plug with a new washer if needed.
- Remove the transmission pan if replacing the filter (common on 545RFE).
- Refill with the correct fluid type and capacity.
- Run the engine, cycle through gears, and check fluid levels again.

FAQ Section
How often should I change transmission fluid in a Jeep Grand Cherokee?
Generally, every 60,000–80,000 miles for normal driving. Heavy towing or off-road use may require more frequent changes.
Can I use aftermarket ATF instead of Mopar?
Yes, but it must be explicitly compatible with ATF+4 or ZF 8HP fluid. Using non-approved fluids risks transmission damage.
Does the 8-speed ZF transmission have a dipstick?
No, it uses a sealed system. Fluid level must be checked via a fill plug at a specific temperature range.
What happens if I overfill transmission fluid?
Overfilling can cause foaming, overheating, and shifting issues. Always fill to the recommended level only.
Is transmission service expensive on a Grand Cherokee?
Yes, especially for the 8-speed ZF units. A fluid and filter service can range from $300–$500 at a dealership, but doing it yourself can save significantly.
Conclusion
Knowing your Jeep Grand Cherokee transmission fluid capacity is critical for smooth shifting and long-term reliability. Older models use ATF+4, while newer 8-speed transmissions require Mopar 8&9 Speed ATF. Whether you’re doing a simple drain & fill or a full service, using the correct fluid and capacity keeps your SUV performing at its best. Order the right transmission fluid today and protect your Grand Cherokee’s transmission.
