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.

We recommend Torque Pro. If your vehicle is not a Nissan, then please read the generic version of this guide as the following information will not apply to all vehicles. If you have Nissan this code, then we hope the below more detailed information helps you. Please comment below the article with your year, model, engine type, and mileage, and we will respond and try to help. The generic description for the P error code is Torque converter clutch TCC solenoid — circuit intermittent. To understand what this code means, we must shortly explain the anatomy behind this assembly.

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. Insert Quotes Quotes Post Reply.

Would a transmission rebuild kit be sufficient? This is an older thread, you may not receive a response, and could be reviving an old thread. I agree, this was kinda depressing. Please consider creating a new thread. Who knowshe might receive a new transmission under warranty. The car runs very smoothly and drives new again. Well the torque converter is part of the power train Home Forums Nissanclub. JavaScript is disabled.

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.

No I am not afraid, but my first reaction was to gain some knowledge about the situation before I visit these clowns. For a peace of mind I made sure to inspect the work. Throckmorton 36 Replies.
