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.

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. When this code is present, it can cause issues with shifting and acceleration, as well as poor fuel economy and performance. This code indicates that the transmission is not shifting correctly, which can be caused by a number of different issues. The transmission system in the Altima contains several shift solenoids, which are responsible for controlling the flow of transmission fluid and allowing the vehicle to shift between gears. The most common symptom of a P code is that the engine will not shift properly, or may become stuck in one gear. Other symptoms may include difficulty accelerating, stalling at idle, and harsh shifts between gears.

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. I agree, this was kinda depressing.
