Checking the transmission fluid level in a 2013 Grand Cherokee requires the engine running and the transmission at operating temperature. The 2013 Jeep Grand Cherokee transmission fluid is a critical component for the longevity of your vehicle’s drivetrain. Without proper fluid levels or the correct type, you risk expensive repairs or complete transmission failure.
This guide walks you through everything you need to know. We cover fluid type, checking procedure, and common issues. Let’s get your Jeep shifting smoothly again.
Understanding Your 2013 Grand Cherokee Transmission
The 2013 Grand Cherokee came with two main transmission options. The most common is the 8-speed automatic, paired with the 3.6L V6 engine. The 5-speed automatic was available with the 5.7L V8. Knowing which one you have is the first step.
Identifying Your Transmission Type
Check your owner’s manual or look at the transmission dipstick if equipped. The 8-speed uses a specific fluid called Mopar ATF+8. The 5-speed uses ATF+4. Using the wrong fluid can cause shifting problems or damage.
- 8-Speed (845RE/850RE): Requires Mopar ATF+8 or equivalent.
- 5-Speed (W5A580/NAG1): Requires Mopar ATF+4 or equivalent.
Most 2013 models with the V6 have the 8-speed. The V8 models typically have the 5-speed. Double-check under the hood for a dipstick. The 8-speed often does not have a traditional dipstick.
2013 Jeep Grand Cherokee Transmission Fluid: Type And Capacity
This is the most important section. Using the correct 2013 Jeep Grand Cherokee transmission fluid is non-negotiable. The wrong fluid can lead to shuddering, slipping, or total failure.
Fluid Specifications For Each Transmission
For the 8-speed (845RE/850RE): Use Mopar ATF+8 (part number 68218925AB). This is a full synthetic fluid designed for high-temperature operation. Capacity is about 9 quarts for a drain and fill. A full flush requires more.
For the 5-speed (W5A580): Use Mopar ATF+4 (part number 05013497AA). This is also a synthetic blend. Capacity is about 7 quarts for a drain and fill.
Do not mix fluids. If you have the 8-speed, do not use ATF+4. The transmission can be damaged quickly. Always check the dipstick or fill plug for the correct fluid type.
Where To Buy The Fluid
You can buy Mopar fluid at dealerships or online. Aftermarket brands like Valvoline and Castrol also make compatible fluids. Look for “ATF+8” or “ATF+4” on the label. Avoid generic “universal” transmission fluids.
- Dealership parts counter
- Online retailers (Amazon, RockAuto)
- Auto parts stores (AutoZone, O’Reilly)
Buying in bulk can save money. A case of 12 quarts is often cheaper than individual bottles. Make sure the bottles are sealed and not expired.
How To Check The Fluid Level
Checking the 2013 Jeep Grand Cherokee transmission fluid is different for each transmission. Follow the correct procedure for your model.
For The 8-Speed Transmission (No Dipstick)
Most 8-speed units do not have a dipstick. They have a fill plug on the side of the transmission. Checking the level requires the vehicle on a lift or jack stands.
- Park the vehicle on a level surface.
- Start the engine and let it idle. The transmission must be at operating temperature (around 180°F).
- Shift through all gears (P, R, N, D) pausing for a few seconds each.
- Leave the engine running in Park.
- Locate the fill plug on the passenger side of the transmission. It is a large hex plug.
- Remove the plug. Fluid should trickle out. If it does not, add fluid through the fill hole until it drips out.
- Reinstall the plug and tighten to spec.
Important: The fluid expands when hot. Checking cold will give a false low reading. Always check at operating temperature.
For The 5-Speed Transmission (With Dipstick)
The 5-speed has a traditional dipstick near the back of the engine bay. It is usually yellow or orange.
- Park on level ground. Engine running and transmission warm.
- Shift through all gears, pausing in each.
- Leave in Park with the engine idling.
- Pull the dipstick, wipe it clean, reinsert fully, then pull again.
- Read the level. It should be between the “Full” and “Add” marks.
- If low, add fluid through the dipstick tube using a funnel.
- Recheck the level after adding a small amount.
Do not overfill. Overfilling can cause foaming and shifting issues. The fluid should be bright red or pink. Dark brown or burnt smell means it needs changing.
When To Change The Fluid
Jeep recommends checking the fluid at every oil change. For normal driving, change the fluid every 60,000 to 100,000 miles. Severe conditions (towing, off-road) require more frequent changes.
Signs You Need A Fluid Change
- Rough or delayed shifting
- Slipping gears
- Whining or humming noise from the transmission
- Burning smell from the fluid
- Fluid appears dark or has particles
If you notice any of these, check the fluid level first. Low fluid can cause similar symptoms. If the level is correct but symptoms persist, a fluid change may help.
Drain And Fill Vs. Flush
A drain and fill replaces about 30-50% of the fluid. It is safer for high-mileage transmissions. A flush replaces all the fluid but can dislodge debris and cause problems in older transmissions.
For the 2013 Grand Cherokee, a drain and fill is recommended every 60,000 miles. If you have over 100,000 miles and never changed the fluid, consider a drain and fill instead of a flush.
Common Transmission Problems In The 2013 Grand Cherokee
Some owners report issues with the 8-speed transmission. These include harsh shifts, hesitation, or shuddering. Often, these are related to fluid level or quality.
Low Fluid Level Symptoms
Low fluid can cause the transmission to slip or shift erratically. It may also cause a delay when shifting from Park to Drive. Check the level first if you experience these.
Fluid Leaks
Leaks are common at the transmission pan gasket or the cooler lines. Look for red puddles under the vehicle. Tighten the pan bolts or replace the gasket if needed. Do not over-tighten.
Overheating
Towing or off-road driving can overheat the transmission. Overheated fluid breaks down and loses its lubricating properties. Install a transmission cooler if you tow frequently.
Step-By-Step Fluid Change Procedure
Changing the 2013 Jeep Grand Cherokee transmission fluid yourself can save money. Here is a general guide. Always consult your owner’s manual for specific torque specs.
Tools And Materials Needed
- Correct transmission fluid (ATF+8 or ATF+4)
- Drain pan
- Socket set and ratchet
- Torque wrench
- Funnel and hose (for fill plug models)
- New transmission pan gasket (if replacing)
- New transmission filter (if accessible)
Drain The Old Fluid
- Jack up the vehicle and secure it on jack stands. Ensure it is level.
- Place a drain pan under the transmission pan.
- Remove the drain plug (if equipped) or loosen the pan bolts.
- Let the fluid drain completely. Remove the pan.
- Replace the filter if your transmission has one. The 8-speed often has a cartridge filter.
- Clean the pan and magnet. Install a new gasket.
- Reinstall the pan and tighten bolts to spec (usually 10-15 ft-lbs).
Refill With New Fluid
- For dipstick models: Pour fluid through the dipstick tube. Add the amount specified in your manual.
- For fill plug models: Use a pump to add fluid through the fill hole until it drips out.
- Start the engine and let it idle. Shift through gears.
- Recheck the level and add more fluid as needed.
- Take the vehicle for a test drive. Recheck the level after driving.
Dispose of the old fluid properly. Most auto parts stores accept used transmission fluid for recycling.
