How To Repair Transmission Tcc
What Does The TCC Solenoid Do?
The principal function of the toque converter clutch or TCC solenoid is to send pressurized fluid to the torque converter's clutch assuasive information technology to achieve lock up in 4th gear based on a signal from the engine control module (ECM). The valve opens allowing for fluid to employ the TCC, and when the signal stops, the fluid is and then vented out which will so disengage the clutch.
Until engine temps reach a certain point, the TCC solenoid volition not allow for lock up.
In essence, the TCC solenoid is similar a computer controlled on and off switch for your 4l60e's torque converter lock up.
Where Is The TCC Solenoid Located
The 4l60e TCC Solenoid is located on the front passenger side of the transmission almost the valve torso. The prototype beneath shows the locations of various solenoids.
Symptoms Of Declining TCC Solenoid
When your 4l60e's TCC solenoid begins to fail, there are a number of obvious signs. The main symptom of a TCC solenoid failure is the converter is not locking upwards. When the converter is not locking upwardly you will notice the engine'southward RPMs staying college nether load at highway speeds.
Some other symptom of a failed TCC solenoid is a error code. Common codes associated with a TCC weather include:
- P0740 – Torque Converter Clutch Circuit Malfuction
- P0741 – Torque Converter Clutch Circuit Performance or Stuck Off
- P0742 – Torque Converter Clutch Circuit Stuck On
- P0743 – Torque Converter Clutch Circuit Electrical
- P0744 – Torque Converter Clutch Circuit Intermittent
- P01870 – Component Slipping
4l60e TCC Solenoid Examination & Replacement
Testing and replacing your 4l60e TCC solenoid is not as daunting of a task as you may retrieve. If y'all have always changed your transmission fluid and filter, then you lot are capable of replacing the TCC solenoid yourself.
The best way to examination the TCC solenoid is to mensurate the OHMs and brand sure its within a suitable range. If it is non, then just supercede information technology.
The video below does a great job of showing and explaining the footstep by step process for testing and replacing your 4l60e TCC solenoid.
How Much Does It Cost To Supersede A 4l60e TCC Solenoid?
The cost associated with replacing a 4l60e TCC solenoid is not too bad, especially if you're comfortable doing it yourself. Typically the TCC solenoid itself costs under $xxx, so betwixt that and fluid and a new filter (might also alter that while you lot're in in that location), yous can be less than $100 into replacing a TCC solenoid yourself in a few hours.
If you were to pay a shop, you can look to pay somewhere between $250 – $500 depending on the labor time needed to exercise the job.
