The 2017 Jeep Grand Cherokee has a strong reputation for performance and comfort, but many owners have faced frustrating transmission issues. If you’re thinking about buying this SUV or already own one, it’s important to know the common problems, warning signs, and possible solutions. Understanding these issues can help you make better decisions and avoid costly repairs.
Common Transmission Problems In The 2017 Grand Cherokee
The 2017 Jeep Grand Cherokee mainly uses an 8-speed automatic transmission, but not all units perform the same. Some drivers report smooth shifting, while others experience repeated troubles. Here are the most frequent issues:
1. Rough Or Hard Shifting
Many owners say the transmission shifts harshly, especially when changing gears at low speeds. This can feel like a sudden jerk or thud. It happens most often between first and second gear, or when slowing down for a stop.
2. Delayed Engagement
Some Grand Cherokees hesitate before going into gear when you shift from park to drive or reverse. This delay can be worrying, and sometimes the SUV rolls slightly before catching.
3. Transmission Slipping
A slipping transmission means the vehicle changes gears for no clear reason, or the engine revs but speed doesn’t increase. This is not only annoying but also dangerous when merging or passing.
4. Warning Lights And Error Codes
The dashboard may show a “Service Transmission” warning or other error messages. These alerts often point to electronic or sensor problems, but they can also mean mechanical trouble inside the transmission.
5. Shuddering Or Vibrations
Some drivers notice shaking or vibrations during acceleration. This shudder can be mild or strong, and it often points to problems with the torque converter or internal clutches.
Causes Behind The Transmission Issues
Several factors contribute to these problems:
- Software Problems: The Grand Cherokee’s advanced transmission relies on computer programming. Sometimes, a software glitch causes rough shifts or delays.
- Faulty Sensors or Solenoids: Sensors tell the computer when to shift. If they fail, the transmission can act strangely.
- Mechanical Wear: Internal parts like clutches and bands can wear out, leading to slipping or shuddering.
- Low or Old Fluid: Transmission fluid cools and lubricates the system. If it’s dirty or low, performance drops quickly.
How Transmission Issues Affect Driving
Transmission troubles don’t just make the ride uncomfortable—they can be unsafe. Sudden jerks or delays might cause you to lose control, especially in traffic. A slipping transmission makes it harder to accelerate when needed. Over time, these problems can damage other parts of the car, leading to higher repair bills.
Data And Owner Complaints
According to the National Highway Traffic Safety Administration (NHTSA), the 2017 Grand Cherokee has received hundreds of complaints about transmission performance. Many reports mention:
- Unexpected shifting at low speeds
- Vehicle hesitation at stop lights
- Transmission failure before 60,000 miles
A study by CarComplaints.com shows the 2017 model is among the worst Grand Cherokees for transmission reliability.

How To Diagnose A Transmission Problem
If you notice odd shifting or warning lights, follow these steps:
- Check for Leaks: Look under the car for red or brown fluid.
- Listen and Feel: Pay attention to any clunks, shudders, or delayed response when shifting.
- Scan for Error Codes: A mechanic can use a scanner to read codes from the transmission control module.
- Test Drive: Drive at different speeds and note when problems happen.
Signs You Shouldn’t Ignore
- “Service Transmission” light on the dashboard
- Burning smell from under the hood
- Difficulty getting into gear
Possible Solutions And Repairs
What can you do if your Grand Cherokee has these problems? Here are some options:
- Software Update: Dealers often fix shifting problems by updating the transmission software. This is usually quick and sometimes free under warranty.
- Sensor or Solenoid Replacement: Faulty sensors can be replaced for a few hundred dollars.
- Fluid Change: Fresh fluid can solve minor issues, especially if old fluid is dirty or burnt.
- Transmission Rebuild or Replacement: If internal parts are badly damaged, a rebuild or new transmission may be needed. This is expensive—often $3,000 to $5,000.
Cost Comparison: Common Repairs
| Repair Type | Average Cost | Time Required |
|---|---|---|
| Software Update | $100 – $200 | 1-2 hours |
| Sensor Replacement | $200 – $400 | 2-3 hours |
| Fluid Change | $150 – $300 | 1-2 hours |
| Transmission Rebuild | $3,000 – $5,000 | 3-5 days |
Preventing Transmission Problems
You can reduce the chance of trouble with regular care:
- Change the transmission fluid every 30,000 to 60,000 miles.
- Get software updates from your dealer.
- Avoid heavy towing or aggressive driving, which stress the transmission.
- Fix leaks and minor issues quickly before they become major problems.
A non-obvious tip: Use only the manufacturer-recommended fluid. Aftermarket fluids can cause shifting problems, even if they claim to be compatible.
Should You Buy A Used 2017 Grand Cherokee?
If you’re shopping for this SUV, ask for maintenance records. Look for cars with regular fluid changes and proof of software updates. Take a long test drive and pay attention to how the transmission shifts. If you feel harsh shifts or hesitation, consider another vehicle or request a lower price to cover possible repairs.
Many owners enjoy their Grand Cherokee with no trouble, but being careful can help you avoid costly surprises.
