How to bypass a TCC solenoid

The Transmission Control Solenoid (TCC) is a crucial component of an automatic transmission system, responsible for regulating the flow of transmission fluid and controlling the transmission gears.

In some cases, the TCC solenoid may fail or malfunction, causing issues with the transmission such as slipping or shifting problems.

I will discuss how to bypass the TCC solenoid in order to temporarily fix these issues and get your car back on the road.

But before beginning, it is important to note that bypassing the TCC solenoid is not a permanent solution and should only be used as a temporary fix.

The TCC solenoid should be replaced as soon as possible to avoid further transmission damage. Additionally, it is important to consult your user manual for specific instructions and to ensure that you are familiar with the transmission system in your vehicle before attempting to bypass the TCC solenoid.

Step 1: Locate the TCC solenoid

The TCC solenoid is usually located on the transmission valve body, which can be found under the vehicle. Consult your vehicle’s service manual for the exact location of the TCC solenoid in your vehicle.

Step 2: Disconnect the TCC solenoid electrical connector

Using a socket wrench, remove the electrical connector from the TCC solenoid. This will disconnect the solenoid from the transmission control module, effectively bypassing it.

Step 3: Test the transmission

With the TCC solenoid disconnected, start the vehicle and test the transmission to ensure that it is functioning properly. If the transmission is shifting smoothly and without slipping, the TCC solenoid has been successfully bypassed.

Step 4: Replace the TCC solenoid

As mentioned earlier, bypassing the TCC solenoid is not a permanent solution. It is important to replace this part as soon as possible to avoid further damage to your transmission.

Consult your vehicle’s service manual for instructions on how to replace the TCC solenoid. If there is no info available, go to an authorized mechanic.

What costs are involved in bypassing or replacing the TCC solenoid?

The cost of bypassing and replacing a TCC solenoid can vary depending on a number of factors such as the make and model of your vehicle, the cost of parts and labor in your area, and whether you choose to do the work yourself or have it done by a professional mechanic.

If you choose to bypass the TCC solenoid yourself, the only cost involved would be the cost of any necessary tools required for your vehicle.

Replacing a TCC solenoid can be more expensive, as it typically requires the removal and disassembly of the transmission valve body.

The cost of the TCC solenoid itself can range from $50 to $200 depending on the make and model of your vehicle.

Additionally, labor costs for replacing a TCC solenoid can range from $100 to $500 or more, depending on the complexity of the job and the hourly rate of the mechanic.

It’s important to note that some vehicles have integrated TCC solenoids that are not replaceable, in this case, the entire transmission valve body or transmission may need to be replaced, and the cost can be significantly higher.

In conclusion, the cost of bypassing and replacing a TCC solenoid can vary depending on a number of factors, and it’s difficult to give a general estimate without knowing the specific details of your vehicle and the location where you live.

It’s always best to get a specific estimate from a reputable mechanic or a dealership that specializes in your car’s make and model.

Conclusion

In conclusion, bypassing the TCC solenoid can provide a temporary fix for issues caused by a malfunctioning one. However, it is important to remember that this is not a permanent solution and this solenoid should be replaced as soon as possible to avoid further transmission damage.
