Reading Time: 7 minutes The 2017 Jeep Grand Cherokee is known for its strong design, off-road ability, and comfortable ride. But for many owners, transmission problems have been a major concern. If you’re thinking about buying this SUV or already own one, it’s important to understand these issues. This guide will help you spot the signs, understand the risks, and learn how to handle transmission troubles with your 2017 Grand Cherokee.
Common Transmission Problems In The 2017 Jeep Grand Cherokee
Transmission issues can show up in different ways. Some are easy to notice, while others may surprise you on the road. Here are the most reported problems for this model:
Rough Or Delayed Shifting
Many owners report that their Jeep’s transmission shifts roughly or with a delay. This often feels like the car is “jerking” or hesitating when changing gears.
- Example: You press the gas pedal, but the SUV pauses before moving forward.
- Common in: Both city and highway driving.
Transmission Slipping
This happens when the transmission changes gears by itself or doesn’t stay in gear.
- Warning signs: Sudden drop in speed, engine revs up, but the car does not accelerate.
- Safety risk: Can be dangerous when merging or passing.
Stuck In Gear Or Won’t Shift
Some drivers find the vehicle won’t shift out of first gear, or gets stuck in park or neutral.
- Electronic problems: Often linked to the vehicle’s computer systems.
- Impact: Limits driving or leaves you stranded.
Warning Lights And Error Codes
A “Check Engine” or “Transmission Over Temp” light may come on.
- OBD-II codes: Errors like P0700 (transmission control system issue) are common.
- What it means: The vehicle’s computer has detected a problem and may limit shifting.
Transmission Fluid Leaks
Leaks can cause a low fluid level, leading to overheating and damage.
- Symptoms: Red or brown fluid under the car, burning smell.
- Result: Can cause permanent transmission failure if not fixed.
What Makes The 2017 Grand Cherokee Transmission Unique?
The 2017 model mostly uses the ZF 8-speed automatic transmission (also called 8HP). This gearbox is modern and efficient, but it depends a lot on software to control shifting.
- Software glitches: Many issues are not due to broken parts, but to problems in the programming.
- Electronic sensors: The transmission uses sensors to “learn” your driving style, but sometimes gets confused.
Quick Comparison: 2017 Grand Cherokee Vs. Other Suvs
Here’s how the 2017 Grand Cherokee transmission compares to similar midsize SUVs:
| Model | Transmission Type | Common Problems | Repair Cost (Avg.) |
|---|---|---|---|
| Jeep Grand Cherokee (2017) | 8-Speed Auto | Rough shifting, slipping | $1,500–$4,000 |
| Ford Explorer (2017) | 6-Speed Auto | Hard shifts, fluid leaks | $1,200–$3,800 |
| Toyota Highlander (2017) | 8-Speed Auto | Delayed shifts (rare) | $1,000–$2,500 |
Insight: The Grand Cherokee’s transmission is more advanced, but also more sensitive to software and electrical issues than some rivals.
Warning Signs: How To Spot Transmission Problems Early
Early detection can save you from expensive repairs. Watch for these signals:
- Transmission warning light on the dashboard
- Unusual noises: Clicking, grinding, or whining during shifts
- Strange vibrations when accelerating or decelerating
- Leaking fluid (red or brown puddles under the car)
- Burning smell from under the hood
Tip: If you notice any of these, check the transmission fluid level first. Low fluid can quickly cause serious damage.
What Causes Transmission Problems In The 2017 Grand Cherokee?
Understanding the reasons behind these problems can help you avoid them or prepare for repairs.
1. Software Glitches
The ZF 8-speed transmission is controlled by computer software. Updates or errors in the software can cause shifting problems.
- Example: A software update might fix one problem but cause a new one.
- Solution: Dealerships can “reflash” or update the transmission software.
2. Faulty Sensors
The transmission relies on sensors for speed, temperature, and gear position.
- If a sensor fails: The system may not shift properly or can lock in one gear.
3. Low Or Dirty Transmission Fluid
Transmission fluid cools and lubricates moving parts.
- Dirty or old fluid: Causes rough shifts, overheating, and damage.
- Leaks: Often from the transmission pan gasket or cooler lines.
4. Mechanical Failures
Though less common, broken clutches or solenoids can cause major problems.
- Expensive: These repairs often cost more than $2,000.

Two Insights Many Owners Miss
- Software matters as much as hardware: Many shifting issues can be fixed with a simple software update, not an expensive repair. Always check for updates first.
- Transmission fluid is not “lifetime”: Even though some dealers say the fluid never needs changing, dirty fluid is a top cause of early failure. Change it as a precaution.
