Reading Time: 7 minutes The 2017 Jeep Grand Cherokee Limited is a popular midsize SUV known for its comfort, style, and strong performance. One of the most important parts of this vehicle is its transmission. For many drivers, understanding how the transmission works, what makes it reliable, and how to care for it is not always easy. This article explains the 2017 Grand Cherokee Limited’s transmission in simple terms, using practical examples and data. If you want to know how this system affects your driving experience, maintenance needs, and what to watch out for, you’ll find clear answers here.
Understanding The 2017 Jeep Grand Cherokee Limited Transmission
The 2017 Grand Cherokee Limited comes with an 8-speed automatic transmission. This means the vehicle can shift through eight different gear levels, giving you smoother acceleration and better fuel efficiency. The automatic system handles gear changes for you, so you don’t have to worry about shifting manually.
Key Transmission Features
- 8-speed automatic (TorqueFlite 8HP70 or 845RE)
- Electronic gear shifter for easy control
- Adaptive shifting learns your driving style and adjusts shifts for comfort or performance
- Supports both 2WD (rear-wheel drive) and 4WD (four-wheel drive) versions
This transmission is designed for a balance of power and smoothness. It helps the Grand Cherokee Limited handle city driving and long highway trips with ease.
Why 8-speed Matters
Older SUVs often had only 4 or 5 gears. The 8-speed transmission:
- Offers better fuel economy (up to 19 mpg city / 26 mpg highway for V6 models)
- Reduces engine strain
- Provides faster, smoother gear changes
- Makes towing and off-road driving easier
Transmission Options: Engine Pairings
The 2017 Grand Cherokee Limited came with two main engine choices, each paired with a version of the 8-speed automatic:
- 3.6L Pentastar V6 (most common)
- 5.7L HEMI V8 (optional upgrade)
Both engines use the 8-speed, but the V8 version has a slightly heavier-duty build to handle more power. This means the transmission is matched to the needs of your engine.
How The Transmission Feels
Drivers often notice:
- Quick shifts at low speeds for city driving
- Longer gears when cruising on the highway
- Manual mode: You can take control and shift using the gear lever if you want more involvement
Common Transmission Problems And Signs
Even good transmissions can have issues over time. For the 2017 Grand Cherokee Limited, most owners report reliable performance. Still, it’s smart to know what to watch for.
Warning Signs
- Rough or delayed shifting: If the gears feel jerky or slow, it might mean a problem.
- Strange noises: Whining, clunking, or humming from under the car can point to transmission trouble.
- Transmission warning light: If this lights up on your dashboard, get your car checked soon.
- Fluid leaks: Red or brown fluid under the car means the transmission system is leaking.
Real-world Example
A driver in Texas noticed that after 70,000 miles, the transmission shifted more slowly in the morning. After a fluid check, the mechanic found the fluid level was low. Fixing the leak early prevented bigger damage.
Maintenance Tips For Longevity
The transmission is one of the most expensive parts to repair. Simple care steps can add years to its life.
Basic Maintenance
- Check transmission fluid every 30,000 to 60,000 miles (Jeep recommends checking at 60,000 miles for normal use)
- Use only ATF+4 or Mopar-approved fluid for the 2017 model
- Replace the transmission filter if needed during fluid changes
- Watch for software updates: Some shifting issues are fixed with a software update at your dealer
Practical Tips
- Warm up your car before driving in cold weather
- Avoid sudden stops and starts
- Don’t tow more than the rated capacity (6,200 lbs for V6, 7,200 lbs for V8 with proper equipment)
Table: Service Schedule Example
Here’s a simple schedule for keeping your transmission healthy:
| Mileage | Service Task |
|---|---|
| 30,000 mi | Check fluid if towing/off-roading often |
| 60,000 mi | Replace fluid and filter |
| Every 15,000 mi | Inspect for leaks and software updates |
