If your Jeep Grand Cherokee won’t go into gear and you’re unsure why, we can assist you in finding the answer, which can alleviate the frustration that mechanical issues with your vehicle may cause.


Why Won’t My Jeep Grand Cherokee Move In Gear?


If your Jeep Grand Cherokee is failing to shift into gear, it is probable that one of the following issues is causing the problem:

  1. Low transmission fluid
  2. Contaminated transmission fluid
  3. Faulty transmission linkage
  4. Transmission valve body problems
  5. Onboard computer failure

Now that we have identified the potential causes for your Jeep Grand Cherokee’s inability to shift into gear, let’s explore the possible solutions to address this issue.

Additionally, you may be interested in learning how to restart a Jeep transmission in your Jeep.

Why Won’t My Jeep Grand Cherokee Move In Gear? Solutions!


Low Transmission Fluid:

Insufficient transmission fluid can lead to inadequate lubrication and cooling of your Grand Cherokee’s shifting mechanisms, potentially preventing it from shifting into gear.

Continuously running low on fluid can cause irreversible damage over time.

Check the transmission fluid level if your Jeep is having trouble shifting into gear, as there may be a leak causing fluid loss.

Promptly address any leaks to prevent further complications.


Contaminated Transmission Fluid:

Contaminated transmission fluid can impair its lubricating and cooling functions, potentially hindering gear shifting.

Regularly changing the transmission fluid according to the maintenance schedule can help prevent this issue.

If it’s been a while since the fluid was last changed, replacing it may resolve the shifting problem.


Faulty Transmission Linkage:

Rough driving conditions can sometimes cause the transmission linkage or cable to disconnect.

For manual transmissions, a noticeable sign of this issue is when the clutch pedal goes directly to the floor when pressed.

While you can attempt to adjust the linkage yourself if you have the necessary tools and workspace, it’s advisable to have a mechanic handle it for optimal results.


Transmission Valve Body Problems:

Contaminated fluids can lead to problems with the transmission’s valve body, necessitating its removal and repair.


Onboard Computer Failure:

Occasional malfunctions in the vehicle’s onboard computer can disrupt communication with the transmission, affecting gear shifting.

In automatic transmissions, the engine control unit (ECU) is responsible for guiding gear changes.

If resetting the ECU doesn’t resolve the issue, a defective ECU may need replacement, as it cannot be repaired.



How Do You Restart A Jeep Transmission?


To address shifting issues, consider restarting the Jeep’s transmission, which can sometimes resolve erratic shifting and eliminate other potential causes.

This technique is applicable to automatic transmissions and can be performed quickly and easily. Follow these steps:

  1. Sit in the driver’s seat and press down on the accelerator pedal.
  2. Turn the key in the ignition, but do not start the Jeep.
  3. While the key is in this position, continue holding down the gas pedal for 30 seconds.
  4. Turn the ignition key back to the “off” position.
  5. Release the gas pedal.

By following these steps, you can reset the transmission and potentially alleviate shifting problems.


Can A Transmission Go Out Suddenly?


A failing transmission will often exhibit warning signs, as mentioned earlier in this post.

However, it’s important to note that there isn’t a fixed timetable for how long a transmission will remain usable once signs of failure appear.

The duration of operability depends on various factors, including the specific symptoms, driving habits, and other circumstances.

In some cases, a failing transmission may continue to function for days to months before experiencing a complete failure.

It’s crucial to remain vigilant about how your Jeep is driving and to address any symptoms promptly once they are noticed.

Early intervention can help prevent further damage and potentially extend the lifespan of the transmission.


Frequently Asked Questions


Why Is My Jeep Not Switching Gears?


The primary and simplest issues to address are low transmission fluid levels or a contaminated transmission filter.

In addition, a worn or stuck pressure solenoid can disrupt the transmission’s ability to maintain appropriate fluid pressure, particularly impacting shifting between first and third gears.

This issue may also stem from wiring or sensor malfunctions.



How Do I Know If My Jeep Transmission Is Bad?


A distinctive indication of Jeep transmission issues is unexplained leakage, which may often go unnoticed as the leaked fluid tends to accumulate underneath the vehicle, out of sight.

If you suspect that your transmission is malfunctioning, inspect underneath the vehicle for any signs of wetness, drips, or pooled liquid.




If your Jeep Grand Cherokee won’t move in gear, potential issues such as low transmission fluid, contaminated fluid, faulty transmission linkage, valve body problems, or onboard computer failure could be the culprits.

Identifying these issues and taking appropriate action can alleviate frustration and ensure smooth operation.

Remember to address symptoms promptly and consider restarting the transmission if necessary.

Additionally, keep an eye out for signs of transmission problems, such as unexplained leakage, to prevent further complications.
