Changing the transmission fluid on a 2020 Jeep Cherokee requires specific ATF+4 fluid and careful procedure adherence. This task is not as simple as draining and filling an engine oil pan. The 2020 Jeep Cherokee transmission fluid change is a job many owners consider to save money at the dealership. However, doing it wrong can lead to shifting problems or even transmission failure. This guide will walk you through everything you need to know, from fluid types to step-by-step instructions.
Your Jeep Cherokee likely has the 9-speed automatic transmission, which is sensitive to fluid condition. Regular fluid changes help prevent harsh shifts and overheating. Ignoring this maintenance can lead to expensive repairs down the road. Let’s get into the details so you can do this job with confidence.
2020 Jeep Cherokee Transmission Fluid Change
Before you start, understand that this transmission does not have a traditional dipstick. You check the fluid level through a special plug on the side of the transmission. This makes the process a bit more involved than older vehicles. You will need to get the transmission to a specific temperature to check the level correctly.
The recommended fluid is Mopar ATF+4. Do not use generic or multi-vehicle fluids. Using the wrong fluid can cause damage. Always check your owner’s manual to confirm the exact fluid specification for your specific engine and transmission combo.
Why Change The Transmission Fluid?
Transmission fluid degrades over time. Heat and friction break down the additives. Old fluid can become dark and gritty, leading to poor lubrication. This can cause hard shifts, slipping, or shuddering. Regular changes extend the life of your transmission.
Jeep recommends a fluid change at certain mileage intervals, often around 60,000 to 100,000 miles for normal driving. If you tow heavy loads or drive in stop-and-go traffic, change it more often. A 2020 Jeep Cherokee transmission fluid change at 60,000 miles is a good rule of thumb for most owners.
Tools And Materials You Will Need
Gather everything before you start. You don’t want to stop mid-job to find a missing tool. Here is a list of what you need:
- Mopar ATF+4 transmission fluid (about 5-7 quarts for a drain and fill)
- Fluid pump (hand pump or bottle pump)
- Torx bit set (T25, T30, T40 are common)
- Drain pan
- Jack and jack stands or ramps
- Socket set and ratchet
- Torque wrench
- Infrared thermometer or scan tool to check fluid temperature
- Funnel with a long hose
- Shop rags and gloves
Make sure you have the correct Torx bits. The drain plug and fill plug often use Torx heads. A 2020 Jeep Cherokee transmission fluid change without the right tools is frustrating and can damage fasteners.
Step-By-Step Procedure For Fluid Change
Follow these steps carefully. Safety first: work on a level surface and chock the wheels. The transmission pan can get very hot if the vehicle was driven recently. Let it cool down before starting.
Step 1: Lift The Vehicle Safely
Jack up the front of the Jeep and place it on jack stands. Make sure it is stable. You need enough clearance to access the transmission pan and fill plug. Ramps can work if you have them, but jack stands are safer for this job.
Step 2: Locate The Drain Plug
Look at the bottom of the transmission pan. There is a drain plug, usually on the side or bottom. It might be a Torx bolt or a hex head. Clean the area around it with a rag to prevent dirt from falling into the fluid.
Step 3: Drain The Old Fluid
Place your drain pan under the plug. Slowly remove the drain plug. Be careful, the fluid might be warm. Let it drain completely. This usually takes a few minutes. You will get about 4 to 5 quarts out, depending on how much was in there.
Step 4: Remove The Fill Plug
There is a fill plug on the side of the transmission case, usually above the pan. Remove it with a Torx bit. This allows air to enter and helps the fluid drain faster. It also lets you add new fluid later. Keep this plug safe.
Step 5: Reinstall The Drain Plug
Once the fluid stops dripping, clean the drain plug and the threads. Install it back and tighten to the manufacturer’s torque specification. Overtightening can strip the threads. Use a torque wrench if you have one.
Step 6: Add New Fluid
Attach your fluid pump to the bottle of ATF+4. Insert the hose into the fill hole on the side of the transmission. Pump the new fluid in. Start with about 4 quarts. Do not overfill yet. You will check the level later.
Step 7: Start The Engine And Warm Up
Start the engine and let it idle. Shift through all the gears (P, R, N, D) slowly, pausing a few seconds in each. This circulates the new fluid. Keep the engine running. The transmission fluid needs to reach a specific temperature for an accurate level check.
Step 8: Check Fluid Level
With the engine running and the transmission in Park, check the fluid temperature. You can use an infrared thermometer on the transmission pan or a scan tool. The ideal temperature is usually between 85°F and 95°F (30°C to 35°C). If it is too cold or too hot, the level reading will be wrong.
Once at the correct temperature, remove the fill plug. Fluid should just start to drip out. If no fluid drips, add more fluid slowly until it starts to drip. If fluid pours out, you have overfilled and need to let some drain out. This step is critical for a proper 2020 Jeep Cherokee transmission fluid change.
Step 9: Reinstall Fill Plug
When the fluid just starts to drip, reinstall the fill plug. Tighten it to the correct torque. Wipe up any spilled fluid. Lower the vehicle from the jack stands.
Common Mistakes To Avoid
Many DIYers make errors during this job. Here are the most common ones:
- Using the wrong fluid: Always use ATF+4. Other fluids can cause slipping or damage.
- Not checking fluid temperature: The level is temperature-sensitive. Checking it cold or hot gives a false reading.
- Overfilling: Too much fluid can cause foaming and overheating.
- Forgetting to remove the fill plug before adding fluid: You need that hole open to add fluid.
- Not tightening plugs to spec: Overtightening can strip threads. Undertightening can cause leaks.
Avoid these pitfalls and your 2020 Jeep Cherokee transmission fluid change will go smoothly.
When To Change The Fluid
Check your owner’s manual for the exact schedule. For most 2020 Cherokees, a fluid change every 60,000 miles is recommended for normal driving. If you tow, off-road, or drive in heavy traffic, consider changing it every 30,000 to 40,000 miles. The fluid condition is a better indicator than mileage alone.
Look at the fluid on the dipstick or drain plug. If it is dark brown or smells burnt, change it immediately. Healthy fluid is red or pinkish. A 2020 Jeep Cherokee transmission fluid change is cheap insurance against transmission failure.
Signs Your Transmission Needs A Fluid Change
Pay attention to how your Jeep drives. These symptoms suggest the fluid is degraded:
- Harsh or delayed shifts
- Slipping out of gear
- Whining or clunking noises
- Shuddering during acceleration
- Burning smell from the transmission area
If you notice any of these, check the fluid level and condition. A simple drain and fill might fix the issue. If the problem persists, consult a professional mechanic.
Cost Comparison: DIY Vs. Dealer
A dealer or shop will charge between $200 and $400 for a transmission fluid change on a 2020 Jeep Cherokee. Doing it yourself costs about $50 to $80 for fluid and a pump. The savings are significant. However, you need the tools and confidence to do the job correctly.
If you are not comfortable with the temperature check or working under the vehicle, pay a professional. A mistake can cost you a transmission. But for many DIYers, the 2020 Jeep Cherokee transmission fluid change is a straightforward weekend project.
