How To Change A Transmission Solenoid On 1990 Ford Taurus 3.8

4l60e TCC Solenoid - CPT 4l60e

What Does The TCC Solenoid Do?

The main role of the toque converter clutch or TCC solenoid is to send pressurized fluid to the torque converter's clutch allowing it to accomplish lock upwardly in 4th gear based on a signal from the engine control module (ECM). The valve opens allowing for fluid to utilize the TCC, and when the betoken stops, the fluid is then vented out which will then disengage the clutch.

Until engine temps accomplish a sure point, the TCC solenoid volition not allow for lock up.

In essence, the TCC solenoid is like a computer controlled on and off switch for your 4l60e'southward torque converter lock up.

Where Is The TCC Solenoid Located

The 4l60e TCC Solenoid is located on the front passenger side of the transmission near the valve trunk. The image 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 master symptom of a TCC solenoid failure is the converter is not locking up. When the converter is not locking up y'all will notice the engine's RPMs staying college under load at highway speeds.

Another symptom of a failed TCC solenoid is a fault code. Common codes associated with a TCC atmospheric condition 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 Excursion Electric
P0744 – Torque Converter Clutch Circuit Intermittent
P01870 – Component Slipping

4l60e TCC Solenoid Test & Replacement

Testing and replacing your 4l60e TCC solenoid is not equally daunting of a task as you may think. If y'all have e'er changed your transmission fluid and filter, and then yous are capable of replacing the TCC solenoid yourself.

The best manner to test the TCC solenoid is to measure the OHMs and brand sure its inside a suitable range. If it is non, and so just supersede it.

The video beneath does a great chore of showing and explaining the step past footstep process for testing and replacing your 4l60e TCC solenoid.

How Much Does It Toll To Replace A 4l60e TCC Solenoid?

The cost associated with replacing a 4l60e TCC solenoid is not too bad, especially if you lot're comfy doing it yourself. Typically the TCC solenoid itself costs under $30, and so between that and fluid and a new filter (might also change that while you lot're in at that place), you can exist less than $100 into replacing a TCC solenoid yourself in a few hours.

If yous were to pay a shop, y'all can wait to pay somewhere betwixt $250 – $500 depending on the labor time needed to do the job.
