The only fix is to replace it. has been associated with the torque converter industry for over 40 years. The Lockup Torque Converter Because the only connection between two sides of a torque converter is a fluid connection, there is always a little slippage, running from about 2-8%. This hard, wear-resistant, and ultra low friction sleeve is. More modern iterations of the torque converter may come with a lockup clutch. That is the only proper way to be a mechanic. As the RPM increases, the slippage reduces until it reaches a specific RPM the converter will stop the slippage and allow the pump to operate at full pressure. The torque converter is a fluid coupling for automatic transmissions that allows the engine to transfer power to the transmission. Of course it doesn't do it in 4, only D, so I'm assuming it's the torque converter. Within the stator is the one-way clutch splined onto the transmission’s stator support shaft. This diagnostic trouble code (DTC) is a generic OBD-II powertrain code.
