Q:

How can you tell if the torque converter is faulty?

A:

Quick Answer

On most modern vehicles, a bad torque converter illuminates the check engine light. The specific problem is then stored in the vehicle's onboard computer, and mechanics read it using a professional scanning tool. Vehicles manufactured after 1980 generally include these sensors. HowStuffWorks recommends using a speed-stall test for checking older torque converters without sensors.

The torque converter includes a pump, turbine and stator. Problems with any of these components can cause the vehicle to shudder on take-off or stopping. They may also cause the transmission to slip while the vehicle moves.

Damage to the torque converter seal often occurs due to overheating of the unit. Transmission fluid then leaks through the failed seal, causing the converter to stop working. Failure of the main transmission torque converter clutch results as the elements of the clutch lock together, often due to severe overloading of the vehicle or distortion of clutch components. Shock to the clutch leads to breakage and converter failure, according to CarsDirect.

If a vehicle with an automatic transmission has difficulty transferring power to the wheels, torque converter replacement or repair is necessary. A damaged torque converter has the potential to eventually shut off an engine. Acceleration problems when operating a vehicle at low speeds indicate an overworked torque converter needing replacement.

  • Q:

    What does a torque converter do?

    A:

    A torque converter is used in vehicles with automatic transmissions to connect the transmission to the engine. The converter transfers movement from the engine to the wheels and allows the engine to continue working slowly when the vehicle is stopped.

    How do you repair a Kawasaki Prairie 360?

    A:

    To repair a Kawasaki Prairie 360, first determine what the problem is, such as a faulty starter, engine misfires or an overheating engine. For a problem where the starter motor does not rotate, first turn the stop switch on and use an electric starter. Listen for a slow turn over, which indicates a problem with the battery. If it is slow, tighten any loose connections, recharge the battery or replace it if the damage is irreparable. Test the starter again.

    How do you clean a catalytic converter?

    A:

    To clean a catalytic converter, pour catalytic converter cleaner into the gas tank, drive until the tank is close to empty, refill the tank, and re-calibrate the vehicle's on-board computer. This helps to maintain components while reducing pollution emissions and eliminating foul smells.

  • Q:

    What does a catalytic converter do?

    A:

    Catalytic converters are emissions devices in vehicles that convert the harmful components in the engine's exhaust gas into harmless ones. This significantly reduces the amount of pollutants that a vehicle releases into the atmosphere. Catalytic converters are muffler-shaped and lie within the exhaust, and they contain catalysts, such as palladium and platinum, arranged in a honeycomb shape that react with the harmful components in the exhaust stream.
