Torque converter clutch solenoid

The cost to replace a failed transmission torque converter clutch solenoid is determine in part, by the vehicle year, make and model. Other factors, such as where the work is done (whether at a local auto repair shop, car dealership or you do-it-yourself) also factors heavily into the cost of repair. We know our parts and products. Replacement of tcc on ford taurus 3. Modern torque converters are duty-cycle controlled (pulsed).

It’s controlled by the TCM. It sends a pulsed voltage signal to the TCC solenoid. The torque clutch prevents lockup at high speeds, and the solenoid for that clutch controls the fluid pressure of the clutch and causes it to open and close at the right time. I work at a mechanics shop, and when this solenoid went out in my transmission, I first checked our parts suppliers and oreilley auto parts. Our supplier was $more and oreilleys was $more.

Torque Converter Clutch Circuit Performance or Stuck Off. This diagnostic trouble code (DTC) is a generic OBD-II powertrain code. Where is the torque converter clutch solenoid located - Answered by a verified Ford Mechanic We use cookies to give you the best possible experience on our website.

One is the torque converter clutch solenoid and the other is the shift solenoid A. The solenoid assembly is located on the exterior of the transmission housing and bolted down by bolts. The words “Stuck Off” in a definition of this code refers to the fact that the torque converter clutch control solenoid is stuck in the “OFF” position, and can therefore not engage the torque converter clutch or lock-up mechanism. This is done to improve fuel economy. When people would complain about torque converter clutch problems and the 125C was installed we ran a quick test.

If the solenoid fails to operate, the car will still run, but with poor fuel economy.

Mechanics would disconnect the four wire connector from the torque converter clutch solenoid. This solenoid allows fluid pressure to reach the torque convertor (which is the coupling between the engine and the transmission input shaft) clutch which only applies during speeds above 40mph and steady throttle. Easy to use parts catalog.

The torque converter lock up clutch is not getting enough hydraulic pressure to fully engage, and it slips at MPH. The solenoid that controls it is continuously pulse modulated on and off keeping the average pressure low. I have written about torque converter clutch problems in other posts but this one will be a little different. Most often when I have a problem with the converter clutch lock up causing an engine stalling condition I find a problem with the tcc solenoid. There is a service bulletin out that adress this issue specifically.

When it fails, the vehicle may experience reduced performance, erratic shifting, and the Check Engine Light will come on. Parts are just part of what we do. Get yours online today and pick up in store. Lock-up piston operation will then be controlled. This happens when the powertrain control module (PCM) over-stimulates the TCC PWM solenoid over time.

Torque converter problems can be the most challenging of all automotive repair issues to diagnose. Fortunately, there are a number of signs to look for, and a few basic tests that will reveal if a faulty torque converter is at the heart of the vehicle’s problems. This reduces the slippage losses in the converter , which increases fuel economy. Transmission will shift from 2nd to 3r and 3rd to 4th(unless Overdrive is off) with the torque converter clutch locked. Once in 4th, the transmission will not downshift unless the ground source is interrupte i. When the solenoid is engage fluid is applied to the torque converter clutch , creating lockup and a direct link between the engine and transmission.

When the torque converter clutch solenoid valve is turned ON, hydraulic pressure is applied to the torque converter clutch. Here are diagrams to help you get the job done below. PWM-pulse width modulation, torque converter clutch apply. Please let us know what happens.

This part is NEW, not used or rebuilt. The 4L80E is a full electronic transmission. In fact, this transmission uses a total of eight solenoids. A torque converter clutch solenoid regulates the amount of transmission fluid that the converter ’s lockup clutch receives.

If this electronic device can’t accurately meter the fluid pressure, then the lockup clutch will not work properly as a result of too much or too little fluid supply. The transmission torque converter clutch is designed to lock the torque converter when the vehicle is in high speed. The second component is the transmission valve body, which on most vehicles holds the torque converter clutch (TTC) solenoid.

The GM torque converter clutch solenoid is basically a hydraulic control valve that is meant to manage the torque converter clutch. Your torque converter is essentially a hydraulic pump that acts as the link between the engine and the transmission. Various components within the torque converter use vanes, similar to a turbine, to act on the transmission fluid within the unit to create a fluid coupling, as well as provide the fluid pressure that the transmission needs. Installed and mounted on what’s known as a flex plate, which is located in between the engine and transmission, the crankshaft will spin this plate, creating the conversion effect.

The TCC solenoid may vary in location dependent upon manufacture but generally it is located as aforementioned. Early signs of a torque converter clutch malfunction are the illumination of warning lights and a noticeable drop in fuel economy, especially on the highway. Re: TCC solenoid replacement?

High Performance Transmission The 700rtransmission torque converter is a special high performance transmission that can only work with specific clutches. Shown is the engine side of the harness, which you will not need for the solenoid testing portion of our How To Service an Accord TCC Solenoid article. Take the connector on the solenoid side and you will be testing to see if the lock up clutch engages inside the torque converter by sending power to PIN 1.
