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. The torque converter clutch is a mechanical coupling inside the automatic transmission that connects it to the engine. Its job is to, when possible, create a link that overrides the torque converter and reduces transmission losses. The clutch is activated and deactivated with a pressurized transmission fluid, whose flow is controlled by a TCC solenoid. To get a more in-depth perspective on the operation of the torque converter and its clutch, please read the generic version of this guide.

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.

But hey They don't replace them with Brand New Transmissions This was fine, as long as it works just as good and I don't experience any problems. Any advice will be appreciated thank you! I have a CEL of P which has to do with the solenoids and the torque converter. BaileyPayne 14 Replies. Sort by Oldest first Oldest first Newest first Most reactions.

This code is triggered when the Powertrain Control Module PCM detects an electrical fault in the torque converter clutch solenoid circuit.

Per the Altima service manual: The Service Manual said:. When i came to a complete stop the revs would go up but it wouldn't engage. Sign up. Throckmorton 36 Replies. Well the torque converter is part of the power train Would a transmission rebuild kit be sufficient? Any advice will be appreciated thank you! For a peace of mind I made sure to inspect the work. Nissan Z Forum. No I am not afraid, but my first reaction was to gain some knowledge about the situation before I visit these clowns. Please consider creating a new thread. Sign up.
