Common Causes
The Jeep Commander is a robust vehicle, but like any other, it has its vulnerabilities. One common issue is the “Transmission Over Temp” warning. Understanding its common causes can help prevent costly repairs and ensure a smooth driving experience.
Low Fluid Levels
One of the primary causes of transmission overheating is low fluid levels. Transmission fluid acts as a lubricant and coolant. When levels drop, the transmission can’t cool properly. This leads to overheating and potential damage.
- Check fluid levels regularly.
- Top up the fluid as needed.
- Use the manufacturer-recommended fluid type.
Fluid Leaks
Fluid leaks are another common cause. Leaks reduce the amount of fluid available to cool the transmission. Identifying and fixing leaks promptly can prevent overheating.
| Leak Source | Potential Fix |
|---|---|
| Transmission Pan | Replace pan gasket |
| Seals | Replace damaged seals |
| Lines | Repair or replace lines |
Old Or Dirty Fluid
Old or dirty fluid can also cause the transmission to overheat. Over time, fluid loses its effectiveness. It becomes contaminated with debris and metal shavings. This reduces its ability to lubricate and cool the transmission.
- Change the transmission fluid according to the vehicle’s maintenance schedule.
- Use high-quality transmission fluid.
- Consider a professional flush for heavily contaminated systems.
Immediate Steps To Take
Facing a Transmission Over Temp warning in your Jeep Commander can be alarming. Taking the right steps quickly can prevent severe damage to your transmission. Here’s a guide on the immediate steps you should take.
Pull Over Safely
When you see the transmission over temp warning, the first thing to do is to pull over safely. Find a safe spot away from traffic. Turn on your hazard lights to alert other drivers.
Stopping immediately helps prevent further damage to the transmission. Continuing to drive can lead to costly repairs.
Check Fluid Levels
Once you have stopped, you need to check the transmission fluid levels. Low fluid levels can cause overheating. Here’s how to check it:
- Open the hood of your Jeep Commander.
- Locate the transmission dipstick. It’s usually marked and easy to find.
- Pull out the dipstick and wipe it clean with a cloth.
- Reinsert the dipstick and pull it out again to check the fluid level.
If the fluid level is low, you may need to add transmission fluid. Make sure to use the type specified in your owner’s manual.
Cool Down The Engine
Allowing the engine and transmission to cool down is crucial. Here’s what you can do:
- Turn off the engine and let it sit for at least 30 minutes.
- Open the hood to help the heat escape faster.
While waiting, avoid driving or restarting the engine. This cooling period helps prevent further overheating.
| Step | Action |
|---|---|
| 1 | Pull Over Safely |
| 2 | Check Fluid Levels |
| 3 | Cool Down the Engine |
By following these steps, you can minimize damage and get back on the road safely. Always consult your owner’s manual for specific instructions related to your Jeep Commander.

Diagnostic Checks
Experiencing a “Transmission Over Temp” warning in your Jeep Commander can be alarming. Performing diagnostic checks helps identify the root cause. This guide will walk you through the essential steps.
Using Obd-ii Scanner
An OBD-II Scanner is a valuable tool for diagnosing transmission issues. Here’s how to use it:
- Locate the OBD-II port under the dashboard.
- Connect the scanner to the port.
- Turn the ignition to the “On” position.
- Follow the scanner instructions to read the error codes.
Common codes related to transmission over temp include P0218 and P0740. These codes provide insights into the specific transmission problems.
Visual Inspection Under The Hood
A visual inspection under the hood can reveal obvious issues. Follow these steps:
- Check the transmission fluid level. Low fluid can cause overheating.
- Inspect the color and smell of the fluid. Burnt or dark fluid indicates a problem.
- Look for leaks around the transmission area.
- Ensure the cooling system is functioning properly.
Addressing these visual cues early can prevent further transmission damage.
| Component | What to Check |
|---|---|
| Fluid Level | Ensure it’s within the recommended range. |
| Fluid Color | Should be red or pink, not dark or burnt. |
| Leaks | No signs of fluid leakage. |
| Cooling System | Fans and radiator working correctly. |
Following these diagnostic checks can save time and money. Identifying issues early can prevent costly repairs.
Maintenance Tips
Regular maintenance can keep your Jeep Commander running smoothly. It helps to prevent issues like Transmission Over Temp. Here are some essential tips to keep your transmission in top shape.
Regular Fluid Changes
Changing the transmission fluid regularly is crucial. Fresh fluid ensures optimal performance and reduces the risk of overheating. Follow the manufacturer’s guidelines for fluid change intervals.
Inspecting For Leaks
Regularly check for leaks under your Jeep Commander. Leaks can cause low fluid levels, leading to overheating. Inspect the transmission pan, seals, and gaskets for any signs of fluid leaks.
Monitoring Fluid Condition
Always monitor the condition of your transmission fluid. Healthy fluid should be clear or light red. If the fluid is dark or smells burnt, it’s time for a change. Use a dipstick to check the fluid regularly.
| Maintenance Task | Frequency | Importance |
|---|---|---|
| Fluid Change | Every 30,000 miles | High |
| Leak Inspection | Monthly | Medium |
| Fluid Condition Check | Every 3 months | High |

Preventive Measures
Transmission overheating is a serious issue for any vehicle. The Jeep Commander is no exception. Taking proactive steps helps ensure your transmission stays cool. Preventive measures can save you from costly repairs.
Proper Driving Habits
Proper driving habits are crucial to maintaining a healthy transmission. Avoid rapid acceleration and hard braking. These actions cause the transmission to work harder. This increases the risk of overheating.
Driving at steady speeds is another good habit. It keeps the transmission fluid temperature stable. Avoiding traffic jams whenever possible also helps. Stop-and-go traffic can overheat your transmission.
Avoiding Overloading
Avoiding overloading your Jeep Commander is another important measure. Carrying too much weight puts extra stress on the transmission. This can quickly lead to overheating.
Check your vehicle’s maximum load capacity. Stay within this limit. Use a trailer if you need to carry heavy items. This helps distribute the weight more evenly.
Using High-quality Fluids
Using high-quality transmission fluids is essential. Low-quality fluids break down faster. This can cause the transmission to overheat.
Make sure to use fluids that meet manufacturer specifications. Check your owner’s manual for details. Regularly check the fluid levels. Low fluid levels can also lead to overheating.
Here is a simple table to remember the key points:
| Preventive Measure | Key Action |
|---|---|
| Proper Driving Habits | Steady speeds, avoid rapid acceleration |
| Avoiding Overloading | Stay within load capacity, use trailers |
| Using High-Quality Fluids | Use recommended fluids, check levels |
