Reading Time: 7 minutes If you are thinking about buying a 2017 Jeep Grand Cherokee or want to know more about its transmission, you are not alone. This SUV is popular for its blend of comfort, off-road capability, and modern features. However, the transmission system is one of the most important parts to understand, especially for new car owners. A reliable transmission means smooth gear changes and better driving, while problems can lead to costly repairs. Let’s look deeper into the 2017 Grand Cherokee transmission, how it works, common issues, maintenance tips, and what makes it stand out.
Overview Of The 2017 Jeep Grand Cherokee Transmission
The 2017 Jeep Grand Cherokee comes with several different transmissions, depending on the engine and trim level. Most models use the 8-speed automatic transmission, which is known for its smooth shifting and good fuel efficiency. Some trims, especially the performance-oriented ones, have slightly different versions of this transmission to handle more power.
- Standard 8-speed automatic: Used in most V6 and V8 models.
- High-performance 8-speed: Found in models like the SRT, designed for more torque and faster shifting.
These transmissions help the Grand Cherokee deliver both comfort for daily driving and power for off-road or towing needs.
Key Features Of The 8-speed Automatic Transmission
The 2017 Grand Cherokee’s 8-speed transmission offers several benefits:
- Smooth gear changes: The extra gears mean shifts are less noticeable.
- Better fuel economy: More gears allow the engine to run at lower RPMs.
- Improved towing: The transmission handles heavy loads well.
- Adaptive shifting: The system learns your driving style and adapts.
For beginners, this means you don’t have to think much about shifting—just drive, and the SUV does the rest.
How The Transmission Works
The transmission’s job is to take power from the engine and deliver it to the wheels. Here’s what happens in simple steps:
- Engine creates power.
- Transmission selects the right gear based on speed and load.
- Power goes to the wheels for smooth acceleration.
An automatic transmission like the one in the Grand Cherokee does all this without needing you to shift gears manually.
Transmission Options By Trim Level
Below is a comparison of which transmission comes with different 2017 Grand Cherokee trims:
| Trim | Engine | Transmission Type |
|---|---|---|
| Laredo | 3.6L V6 | 8-speed automatic |
| Limited | 3.6L V6 or 5.7L V8 | 8-speed automatic |
| Overland | 3.6L V6 or 5.7L V8 | 8-speed automatic |
| Summit | 3.6L V6 or 5.7L V8 | 8-speed automatic |
| SRT | 6.4L V8 | High-performance 8-speed |
| Trailhawk | 3.6L V6 or 5.7L V8 | 8-speed automatic |
Most buyers will use the standard 8-speed, but the SRT has a stronger version for more power.
Common Transmission Problems
Even though the 2017 Grand Cherokee’s transmission is advanced, there are some common issues owners may face:
- Rough or delayed shifting: Some drivers notice the transmission hesitates or shifts with a jolt, especially when cold.
- Warning lights: Transmission or check engine lights may turn on if there is a problem.
- Leaking transmission fluid: You may see red or brown fluid under the vehicle.
- Transmission slipping: The engine revs, but the car does not move as quickly as expected.
If you notice any of these signs, it is important to address them quickly to avoid bigger problems.
Why Do These Problems Happen?
- Software glitches: Sometimes, the transmission’s computer needs a software update.
- Low or dirty fluid: Old or low transmission fluid can cause rough shifts.
- Worn parts: Over time, clutches and gears wear down.
Maintenance Tips For A Healthy Transmission
You can extend the life of your Grand Cherokee’s transmission with a few simple steps:
- Check fluid levels regularly. The right amount and type of fluid keeps the transmission cool and clean.
- Change transmission fluid as needed. Jeep recommends fluid changes around every 60,000 miles, but check your owner’s manual.
- Avoid aggressive driving. Sudden starts and stops put extra stress on the transmission.
- Fix leaks right away. Low fluid can quickly lead to damage.
- Get software updates. Dealers may offer free updates that improve shifting.
These steps can help prevent most transmission problems and keep your SUV running smoothly.

Real-world Performance
Many owners like the quick, smooth shifts of the 8-speed automatic. It feels modern compared to older Jeep models. Owners often mention:
- Good highway fuel economy. The 8-speed helps achieve up to 26 mpg on the highway with the V6.
- Confident towing. With the V8, towing capacity reaches up to 7,200 pounds—thanks in part to the strong transmission.
- Off-road capability. The transmission works well with Jeep’s 4×4 systems, giving good control on rough terrain.
However, a few users report slow or hard shifting, especially at low speeds or in cold weather. Most of these issues are fixed by the dealer with a software update or fluid change.
Transmission Fluid: What You Need To Know
The right transmission fluid is critical for the 2017 Grand Cherokee. Using the wrong type can cause damage. For most models:
- Use Mopar 8 & 9 Speed ATF (Automatic Transmission Fluid) or a fluid that meets the same specs.
- Check the fluid level with the engine running and transmission in park.
- Fluid should be bright red and not smell burnt.
Changing the fluid is not as simple as an oil change. Many owners prefer to let a professional handle it.

Transmission And Off-roading
The 2017 Grand Cherokee is famous for its off-road ability. The 8-speed transmission works with Jeep’s 4×4 systems to give you more control in mud, sand, or snow. It also has features like:
- Low-range gearing: For steep hills or tough terrain.
- Hill descent control: Helps you go down hills slowly and safely.
For off-road fans, the transmission is a key reason the Grand Cherokee is so capable.
Tips For Buying A Used 2017 Grand Cherokee
If you are considering a used model, keep these points in mind:
- Ask for service records. Make sure transmission fluid changes have been done.
- Test drive: Pay attention to shifting—look for smooth changes and no delays.
- Check for recalls: Make sure all updates and recalls are complete.
- Certified pre-owned: These models are inspected and often have extra warranty.
A well-maintained transmission will give you years of trouble-free driving.
Non-obvious Insights For Beginners
Many first-time buyers miss these important points:
- Transmission software updates are as important as fluid changes. They fix rough shifting and improve performance.
- Towing or carrying heavy loads puts extra stress on the transmission. If you tow often, change the fluid more often than the manual says.
- Cold weather can make shifting feel rougher at first. This is normal, but if it does not improve after a few minutes, get it checked.
- Aftermarket transmission coolers can help if you tow heavy trailers regularly.
Paying attention to these tips can prevent many problems that catch new owners off guard.
