When does the TCC solenoid apply in overdrive?
First verify the condition/concern. In most cases the TCC solenoid applies in overdrive when commanded by the PCM.
How does a torque convertor clutch ( TCC ) work?
The torque convertor clutch is locked changing the fluid coupling to a mechanical one. This solenoid uses power and ground sent through a coil of wires which creates a magnetic field to pull or push a central metal rod. When the solenoid is energized or de-energized, it directs fluid flow through the valve body of the transmission.
How is the torque converter clutch controlled by a solenoid?
The converter clucth does not lockup at these low speeds therefore heat is generated. This clutch is controlled by an electrical solenoid. The torque convertor clutch is locked changing the fluid coupling to a mechanical one.
Can a stuck solenoid be removed from a transmission?
If the transmission is not burned and you continue to have issues, you could have a stuck shift valve. In these cases, you would be required to remove the valve body and free the stuck valve to fix the problem. The governor pressure solenoid contained in this kit is packed in fluid from the factory.
Why is my torque converter not working on my Jeep Wrangler?
It means that the Wrangler ‘s computer has detected that there is an issue with the torque converter clutch (TCC) solenoid circuit. The TCC “locks” the drivetrain, which allows for a true mechanical connection between the transmission and the engine.
What causes a Jeep Wrangler p0740 to not work?
If there isn’t enough transmission fluid, the transmission will not be able to operate normally. There are many symptoms of low transmission fluid. The most noticeable one is going to be the transmission slipping. If the transmission fluid is dirty or burnt, it can make the transmission behave in a way that is not normal and throw the P0740 code.
Why does the p0740 have a torque converter clutch?
The TCC “locks” the drivetrain, which allows for a true mechanical connection between the transmission and the engine. In effect, this allows an automatic transmission to function like a manual transmission at certain speeds and engine loads, and eliminates all slipping from the transmission. The symptoms of P0740 vary greatly.
