Understanding the final bill for any car repair can be confusing. To provide clarity, we’ve broken down the estimated costs for replacing the shift interlock solenoid on your Acura TSX. These figures provide a solid baseline, but remember they don’t include taxes, shop fees, or costs for any related repairs that might be discovered during the job.
### Cost Summary: Parts vs. Labor
For this specific repair, the cost is split fairly evenly between the new part and the technician’s time.
| Cost Component | Estimated Price Range |
| :— | :— |
| **Parts Cost** | $124 |
| **Labor Cost** | $97 – $122 |
| **Total Estimated Cost** | **$221 – $247** |
*This estimate is a national average. For a precise quote based on your specific location and vehicle details, use a fair price estimator tool.*
### How Your Location Impacts the Final Bill
Labor rates are one of the biggest variables in automotive repair. A certified technician in a major metropolitan area like Los Angeles or New York City will have a higher hourly rate than one in a smaller town in the Midwest. This can swing your total cost by $50 or more.
* **High-Cost Urban Areas:** Expect to be at the higher end of the $221 – $247 range, or potentially slightly above.
* **Lower-Cost Rural Areas:** You will likely pay closer to the lower end of the estimate.
### OEM vs. Aftermarket Parts: A Cost Comparison
For a component like the shift interlock solenoid, you have two main options:
* **OEM (Original Equipment Manufacturer):** This part is made by Honda/Acura or their direct supplier. It guarantees a perfect fit and function but typically comes at a premium price. The $124 parts estimate reflects an OEM part.
* **Aftermarket:** These parts are made by third-party companies. They are often less expensive but quality can vary. For a critical safety and function component, most automotive experts recommend sticking with an OEM part to ensure reliability.
## Key Factors That Influence the Replacement Cost
Beyond parts and labor, several other factors can affect the final price you pay for your **Acura TSX Auto Trans Brake Shift Interlock Solenoid Replacement**.
### Your Acura’s Year and Mileage
The Acura TSX was produced for two generations (2004-2008 and 2009-2014). While the replacement process is similar, minor differences in the center console design between these generations can slightly alter the labor time. On higher-mileage vehicles, the plastic trim pieces around the shifter can become brittle and may crack during removal, potentially adding the cost of a replacement trim piece to your bill.
### Dealership vs. Independent Repair Shop
Where you choose to have your vehicle serviced plays a significant role in the overall cost.
* **Acura Dealership:** Dealerships exclusively use OEM parts and have factory-trained technicians. Their labor rates are typically the highest, but you’re paying for specialized expertise.
* **Independent Repair Shop:** A trusted local mechanic often has lower labor rates and may offer you the choice between OEM and high-quality aftermarket parts. This is usually the most cost-effective option.
* **Chain Repair Shops:** National chains can be competitive on price, but ensure the technicians have experience with Acura or Honda vehicles.
### The “While You’re In There” Repairs
A good technician will inspect related components when they access the shifter assembly. According to RepairPal, it’s highly recommended to replace any worn bushings in the shifter assembly at the same time. These small plastic or rubber parts wear out over time and can cause sloppy shifter feel or even prevent the car from engaging gears properly. Replacing them while the console is already disassembled adds minimal labor cost and can prevent a separate, more expensive repair down the road.
## The Mechanic’s Perspective: Diagnosis and Replacement
Understanding what happens at the shop can demystify the repair process and its cost.
### How a Technician Diagnoses a Faulty Solenoid
When you report being unable to shift from park, a technician follows a logical diagnostic path:
1. **Initial Checks:** They first confirm the basics: the ignition key turns properly, and the brake lights work when you press the pedal. If the brake lights don’t work, the problem is likely the brake light switch, not the solenoid.
2. **Listen for the Click:** The technician will press the brake pedal and listen for the solenoid’s audible “click” near the shifter. No click points toward a problem with the solenoid or its circuit.
3. **Electrical Testing:** If no click is heard, the technician will check the relevant fuses. If the fuses are good, they will access the solenoid’s wiring connector to test for power and ground with a multimeter.
4. **Confirmation:** If the solenoid receives proper voltage when the brake is pressed but fails to actuate, it is confirmed to be faulty and requires replacement.
### Step-by-Step: The Replacement Process
Replacing the solenoid can range from simple to moderately complex, depending on the vehicle.
1. **Access the Shifter:** The technician will carefully remove the center console trim panels surrounding the gear selector to gain access to the shifter assembly.
2. **Disconnect and Remove:** The solenoid’s electrical connector is unplugged. Any linkages connected to the solenoid’s pushrod are detached. Finally, the fasteners holding the solenoid to the shifter assembly are removed.
3. **Installation:** The new solenoid is mounted, and the fasteners are secured. The linkages and electrical connector are reconnected.
4. **Testing and Reassembly:** Before reassembling the console, the technician will test the new solenoid by starting the car, pressing the brake, and ensuring the shifter moves freely through all gears. Once confirmed, the console trim is reinstalled.
## Is Your Shift Interlock Solenoid Failing? Common Symptoms
Catching the problem early can save you the headache of being stuck somewhere. Watch for these warning signs.
* **Stuck in Park:** This is the most common and definitive symptom. Your car starts, but the gear shifter will not move out of the “P” position, even with your foot firmly on the brake.
* **Intermittent Shifting Issues:** Sometimes the solenoid may work intermittently before failing completely. You might find it gets stuck one day but works fine the next.
* **No “Click” Sound:** You may be used to hearing a faint click from the console area when you press the brake pedal before shifting. If this sound disappears, the solenoid is likely not activating.
* **Key Stuck in Ignition:** On some vehicles, a faulty shift interlock system can prevent you from turning the key to the “off” position and removing it.
## Smart Strategies to Save Money on Your Repair
While the **Acura TSX Auto Trans Brake Shift Interlock Solenoid Replacement Cost** isn’t extreme, you can still take steps to ensure you’re getting the best value.

### Can You Replace the Solenoid Yourself? A DIY Assessment
For the mechanically inclined, this repair can be a potential DIY project.
* **Difficulty:** Moderate. It requires careful removal of interior trim without breaking clips, basic hand tools, and a foundational understanding of simple electrical circuits.
* **Savings:** You can save the entire labor cost of $97 – $122.
* **Recommendation:** Before you begin, watch a few video tutorials specific to your Acura TSX generation. If the process seems too intricate or you’re uncomfortable with electrical diagnostics, it’s best to leave this job to a professional. Getting stuck halfway through a repair is more costly in the long run.
## Frequently Asked Questions (FAQ)
### How long does it take to replace a shift interlock solenoid?
A professional technician can typically complete this job in about 1 to 1.5 hours.
### Is it safe to drive with a failing shift interlock solenoid?
If the solenoid fails, you won’t be able to shift out of park, so you won’t be able to drive at all. If it’s failing intermittently, you risk getting stranded the next time it fails completely. It is not a safety risk while driving, but it is a major reliability issue.
### Can a blown fuse cause my shifter to be stuck in park?
Yes, absolutely. The solenoid operates on an electrical circuit protected by a fuse. A technician will always check the fuse first, as it’s a simple and inexpensive fix.
### What is the shift lock override, and can I use it?
Most automatic vehicles, including your Acura TSX, have a small slot near the shifter labeled “Shift Lock Release.” You can insert your key or a small screwdriver to manually override the lock and move the shifter into neutral or drive. This is an emergency measure designed to get your car onto a tow truck or out of a dangerous spot—it is not a permanent solution.
## Next Steps for Your Acura TSX
