Transmission problems in the 2020 Jeep Cherokee have been linked to software glitches and hardware failures. If you own this SUV, you might have noticed jerky shifts or a sudden loss of power. These issues aren’t rare, and understanding them can save you time and money.
The 2020 Jeep Cherokee transmission problems often show up without warning. Many drivers report hesitation when accelerating from a stop. Others hear clunking noises during gear changes. Let’s break down what’s happening under the hood.
2020 Jeep Cherokee Transmission Problems
The 2020 model year Cherokee uses a 9-speed automatic transmission. This system was designed for smooth driving and fuel efficiency. But real-world reports tell a different story. Owners have filed complaints with the NHTSA about sudden jerking and delayed responses.
Some issues stem from the transmission control module (TCM). The TCM manages shift timing and gear selection. When it malfunctions, you might feel harsh shifts or see the check engine light. Other problems involve physical parts like the valve body or torque converter.
Common Symptoms Of Transmission Failure
Recognizing early warning signs can prevent a full breakdown. Here are the most reported symptoms:
- Jerking or shuddering during acceleration
- Delayed engagement when shifting from Park to Drive
- Whining or buzzing noises from the transmission
- Transmission slipping out of gear while driving
- Burning smell coming from the engine bay
- Check engine light or transmission warning light on the dash
If you notice any of these, act quickly. Ignoring them can lead to costly repairs. A simple software update might fix some issues. But hardware failures often require part replacements.
Software Glitches And TCM Issues
Jeep released several software updates for the 2020 Cherokee transmission. The TCM controls shift points and clutch pressure. When the software is buggy, the transmission behaves erratically. You might feel a hard shift between 2nd and 3rd gear. Or the car might lurch forward when you stop.
Dealerships can reflash the TCM with updated firmware. This process takes about an hour. It’s often covered under warranty. But if your warranty expired, expect to pay around $150 to $200 for the update.
Some owners report that software updates only help temporarily. The problems return after a few months. In those cases, the TCM itself might be faulty. Replacing the module costs between $500 and $800, including labor.
Hardware Failures: Valve Body And Torque Converter
Hardware problems are more serious than software glitches. The valve body controls hydraulic pressure inside the transmission. When it fails, you might experience hard shifts or no movement at all. Replacing a valve body costs $800 to $1,200.
The torque converter is another weak point. It connects the engine to the transmission. A failing torque converter causes shuddering at highway speeds. You might also hear a rattling noise. Replacement runs $1,000 to $1,500.
In rare cases, the entire transmission needs replacement. That job costs $3,000 to $5,000. Most owners avoid this by catching problems early.
Transmission Fluid Leaks And Overheating
Leaks are a common cause of transmission failure. The 2020 Cherokee uses special ATF+4 fluid. If the fluid level drops, the transmission overheats. Overheating damages seals and clutches.
Check for red or brown puddles under your car. Also look for fluid on the transmission pan gasket. A leaky gasket costs about $200 to fix. But if the transmission ran low on fluid, internal damage might already be done.
Overheating can also happen if you tow heavy loads. The Cherokee’s transmission cooler is small. Adding an aftermarket cooler helps prevent heat damage. This upgrade costs $300 to $500.
How To Diagnose Transmission Problems
You don’t need to be a mechanic to spot issues. Start by checking the transmission fluid level. Park on level ground, let the engine run, and pull the dipstick. The fluid should be bright red and smell sweet. Dark or burnt fluid means trouble.
Next, test drive the car. Accelerate gently and note any jerks. Drive at highway speeds and feel for vibrations. Listen for unusual noises. If something feels off, record a video with your phone. This helps the mechanic diagnose faster.
Finally, scan for trouble codes. A cheap OBD2 scanner can read transmission codes. Common codes include P0700 (transmission control system) and P0730 (incorrect gear ratio). Write down the codes and research them online.
Step-By-Step DIY Checks
Try these simple checks before visiting a shop:
- Check fluid level and condition
- Inspect for leaks under the vehicle
- Listen for unusual noises during driving
- Note any warning lights on the dash
- Test all gears, including reverse
- Check for delayed engagement when shifting
If you find a leak, tighten the pan bolts. But don’t overtighten them. The pan is aluminum and can crack. If the fluid is low, top it off with ATF+4. Do not use generic transmission fluid.
Repair Options And Costs
Repair costs vary based on the problem. Here’s a breakdown of common fixes:
- Software reflash: $150–$200
- TCM replacement: $500–$800
- Valve body replacement: $800–$1,200
- Torque converter replacement: $1,000–$1,500
- Transmission rebuild: $2,500–$4,000
- Transmission replacement: $3,000–$5,000
Warranty coverage helps a lot. The 2020 Cherokee came with a 5-year/60,000-mile powertrain warranty. If your mileage is under 60k, most repairs are free. Check your warranty status with a dealer.
Extended warranties are worth considering. Third-party plans cover transmission repairs. They cost $1,500 to $3,000 for 5 years. Compare plans before buying.
Dealership Vs Independent Shop
Dealerships have specialized tools and trained techs. They can update software and diagnose complex issues. But they charge higher labor rates, often $150 per hour.
Independent shops are cheaper, around $100 per hour. But they might not have the latest software updates. For simple repairs like fluid changes, an independent shop works fine. For TCM or valve body issues, go to the dealer.
Some owners prefer transmission specialists. These shops focus only on transmissions. They often have lower prices and faster turnaround. Search for “transmission shop near me” and read reviews.
Preventive Maintenance Tips
Preventing problems is cheaper than fixing them. Follow these tips to extend your transmission’s life:
- Change transmission fluid every 30,000 miles
- Use only ATF+4 fluid
- Avoid aggressive driving and hard launches
- Don’t tow beyond the Cherokee’s capacity (4,500 lbs)
- Install an aftermarket transmission cooler if you tow often
- Check fluid level monthly
- Address leaks immediately
Regular fluid changes remove contaminants. Old fluid loses its lubricating properties. A fluid change costs $150 to $300 at a shop. Doing it yourself costs about $80 for fluid and a filter.
Also, keep up with software updates. Check with your dealer for any open recalls or TSBs (Technical Service Bulletins). Jeep has issued several TSBs for the 2020 Cherokee transmission. These bulletins describe known issues and fixes.
TSB And Recall Information
Several TSBs affect the 2020 Cherokee transmission. TSB 21-001-20 addresses harsh shifts. TSB 21-002-20 covers delayed engagement. Both involve software updates. If your car has these symptoms, ask the dealer to apply the TSB.
There are no major recalls for the transmission itself. But a recall exists for the transmission oil cooler line. The line can leak and cause a fire. Jeep will replace it for free. Check your VIN on the NHTSA website to see if your car is affected.
Some owners report that the TSB updates don’t fix everything. In those cases, the dealer might replace the valve body or TCM. This is covered under the powertrain warranty.
Owner Experiences And Forum Reports
Online forums are full of 2020 Cherokee transmission stories. On JeepCherokeeClub.com, one owner wrote: “My 2020 Cherokee started jerking at 15,000 miles. The dealer reflashed the TCM, and it helped for a month. Then the jerking came back. They replaced the valve body under warranty, and now it’s fine.”
Another owner on Reddit said: “I had the transmission replaced at 40,000 miles. The torque converter failed and took the whole transmission with it. Thank god for the warranty. The new transmission shifts smoothly.”
Not all stories are negative. Some owners report no issues at all. One driver said: “I have 50,000 miles on my 2020 Cherokee. No transmission problems. I change the fluid every 30k miles and drive gently.”
These mixed reports show that build quality varies. Some cars are trouble-free, while others have persistent issues. If you’re buying a used 2020 Cherokee, check the service history. Look for transmission repairs or software updates.
What To Do If Your Transmission Fails
If your transmission fails completely, stay calm. First, tow the car to a safe location. Don’t drive it with a failed transmission. You could damage other components.
Contact your dealer if the car is under warranty. They’ll arrange a loaner car and fix the issue. If the warranty expired, get quotes from multiple shops. Compare prices and ask about warranties on the repair.
Consider selling the car if repair costs are too high. A used 2020 Cherokee with a bad transmission sells for $5,000 to $8,000 less than a working one. You might be better off selling as-is and buying a different vehicle.
