This problem used to be seen in older vehicles with neglected engine cooling systems, but is becoming common in later model cars and trucks that have followed their maintenance schedules. They weren t fishing for a rebuild because they didn t offer that. The flexplate plays a similar role to that played by the flywheel in manual transmission vehicles. If the converter is slipping and not engaging as it should you will probalby notice is more when the transmission has warmed up. The torque converter clutch is also known as a lock up converter. High-performance cars and heavy duty trucks clutch replacements will likely cost more than your average compact economy sedan. Torque Converters: We also have Remanufactured Torque Converters available for $400 for OEM stall speed (CR70X). Offhand, if it's vehicle speed and it smooths when either in neutral or stops at some point during deceleration; it would typically be a bad transmission output bushing or soft/bad mounts. In this article we are going to talk about the part of the automatic transmission called the torque converter. we operate in a coal environment. Bad acceleration as low speeds – Low power when driving at lower speeds indicates a torque loss caused by improper rotation of the stator. How To Tell If Your Transmission Pump Stator Is Broken Or Spun (And What To Do If It Is) In most automatic transmissions, the torque converter is mated to the pump of the transmission in two places: the input shaft and the stator (also called a stator tube or stator support). If you notice a reddish puddle under your car after it's been sitting for a while, you'll want to get your transmission inspected, as a low transmission fluid level can cause other serious problems.
