A torque converter is among the most crucial component in an automatic transmission. When you're experiencing a transmission shudder, it might be an early sign that your car's torque converter is on its way out, and requires a replacement. Torque converters aren't all too expensive by themselves. You can find a good yet suitable torque converter for your car for around $200 to $500. However, a torque converter replacement cost ramps up quickly once you take into account the labor required. As replacing a torque converter requires first detaching the transmission from your engine, it takes a lot of time and energy. Most workshops will raise the final tally to between $600 to $1,000 just to cover the labor charges needed to replace a torque converter.
