For a peace of mind I made sure to inspect the work. Do i need a new TC? AVS Forum.

We recommend Torque Pro. In simple terms, a torque converter is a hollow drum that is attached to the engine, and encloses a turbine that is attached to the transmission, with no direct contact between the drum and the turbine. Put in another way, this means that since some transmission fluid is forced through the small gap between the vanes on the drum and those on the turbine as the outer drum rotates, the fluid that is lost in this way cannot contribute to the transmission of power from the engine to the transmission. In short, this means that automatic applications without torque converter lockup clutches are less fuel-efficient than applications that do have torque converter lockup clutches. To address all of these issues, car manufacturers have developed mechanical clutches that lock the two halves of the torque converter together; much like a clutch in a manual application that forms a mechanical link that locks the engine and transmission together. The practical advantage of this is not only that slippage can be eliminated, which increases fuel efficiency and reduces emissions, but also that under certain conditions, slippage can be induced to both make gear shifts smoother, and to protect vulnerable transmission components against the effects of over torque conditions. In terms of operation, a torque converter lockup clutch depends on pressurized fluid either to engage, or to disengage friction surfaces that loosely resemble clutch components found in manual applications. When the PCM determines based on input data from among others the engine speed sensor, vehicle speed sensor, and throttle position sensor s that a gear shift may be harsh, it may momentarily relieve some of the pressure keeping the lockup clutch engaged to induce some slippage. From the above, it should be obvious that for the torque converter lockup clutch to work as intended, all of the components in the system need to be in perfect working order.

This code is triggered when the Powertrain Control Module PCM detects an electrical fault in the torque converter clutch solenoid circuit. The torque converter clutch solenoid is responsible for controlling the amount of torque that is transferred between the engine and transmission during gear changes. This code can be caused by a variety of issues, such as a faulty solenoid, wiring issue, or a short in the circuit.

Home Forums Nissanclub. I received a call from the service tech at AM informing that there was a whole bunch of error codes coming from the transmission and that it will need to be replaced. Nissan Z Forum. Anyways, I scheduled a appointment and will be seen first thing tomorrow morning. After taking a look under the hood I noticed the shiny new replaced transmission.

This is not caused by electrical malfunction circuits open or shorted but by mechanical malfunction such as control valve sticking, improper solenoid valve operation, malfunctioning oil pump or torque converter clutch, etc.
