Modern vehicles’ onboard computer system monitors and controls various aspects of their operation, including the transmission. The system generates warnings when an issue is detected. A warning message Chrysler Pacifica and Chrysler 300 owners may encounter is “Service Trans Press Brake When Stopped” or “Service Trans Press Brake When Stopped Key Off Engine to Engage Park” if the car has any potential issues within the transmission system. The most common reasons behind this warning are a faulty transmission shift interlock switch, transmission problems, and software issues.
In this article, I’ll go through the typical reasons for this Chrysler warning and what you can do to solve it. Let’s get started!

What Causes the Service Trans Press Brake When Stopped Warning?
Several factors may trigger the “Service Trans Press Brake When Stopped” or “Service Trans Press Brake When Stopped Key off Engine to Engage Park” warning in your Chrysler. Let’s understand the common causes in detail:
Faulty Transmission Shift Interlock Switch
The transmission shift interlock switch prevents the driver from shifting the vehicle from the “Park” position unless the brake pedal is depressed. If this switch malfunctions, it may incorrectly prevent the driver from shifting into “Park” even when the brake pedal is pressed. This can result in the warning message appearing as a safety precaution.
Transmission Problems
Issues within the transmission itself can lead to this warning message. These problems can range from mechanical issues, such as faulty solenoids or clutch packs, to electrical problems, such as sensor failures or wiring harness issues.
Mechanical problems can disrupt the regular operation of the transmission, causing it to behave erratically or inconsistently.
Electrical problems can result in inaccurate sensor readings, leading to safety concerns that trigger the warning.
Software Glitch
Often, software glitches in the Transmission Control Unit (TCU) can be the primary source of the warning message. The TCU controls various aspects of the transmission’s operation, and a software malfunction can lead to erroneous warnings. Software glitches can sometimes be resolved through updates or reprogramming of the TCU.
What Should You Do if the “Service Trans Press Brake When Stopped” Warning Arises?
When your Chrysler displays the “Service Trans Press Brake When Stopped” warning, you have to take a systematic strategy to diagnose as well as solve the problem. You can follow these thorough steps:
1. Safely Stop the Vehicle
When confronted with the “Service Trans Press Brake When Stopped” warning while driving your Chrysler Pacifica, gradually reduce speed and bring your vehicle to a complete stop in a secure location. Maintain the transmission in the “Drive” position until the full stop is achieved to ensure control and safety.
2. Press the Brake Pedal and Shift Gears
In compliance with the warning message, apply firm pressure to the brake pedal while your vehicle is stationary. This step is vital to prevent accidental vehicle movement and align with the safety protocol associated with the warning.
While maintaining firm brake pedal pressure, attempt to shift the transmission into various gears such as “Drive,” “Neutral,” “Reverse,” and “Park.” When doing these tasks, watch closely how the transmission reacts and whether the warning message endures.
3. Restart the Vehicle
Turn off the ignition, remove the key, and wait approximately 30 seconds before restarting your vehicle. Occasionally, this simple action can clear minor sensor or software glitches. Check your dashboard for any additional error messages or warning lights upon restarting. After restarting the vehicle, check the dashboard to see whether there are any error messages or warning lights.
4. DIY Inspection
For those comfortable with vehicle maintenance, consider conducting basic inspections before seeking professional assistance. Examine the shift interlock and brake pedal for any visible issues or obstacles.
Additionally, verify the transmission fluid level, referring to your Chrysler’s owner’s manual if applicable. Insufficient level of transmission fluid is a common reason for transmission issues.
Lastly, inspect the wiring harnesses behind the glovebox and connectors around the transmission for loose or damaged connections.
5. Contact Your Dealership
If the warning message persists after the above steps, contact a professional mechanic or visit a Chrysler dealership. Share with them the details of your experience with the warning message and the actions you have taken already.
To identify the primary reason for the warning message, the technicians can check the error codes stored in your Chrysler computer system using an OBD-II scanner.
Also, tell them to do a thorough inspection, including checks of the transmission, brake systems, sensors, and wiring.
They will suggest the required fixes to resolve the issue after the cause has been found. It may involve repairing or replacing parts and updating software.
