A bad torque converter interferes with the transfer of power from the engine to the transmission of a vehicle. It causes transmission overheating, slipping and shuddering and poor fuel economy. Vehicle owners sometimes think their transmission is bad when the real problem is the torque converter.Know More
With a bad torque converter, a vehicle must work harder to maintain the same speed. The engine operates at a higher number of revolutions per minute, decreasing fuel economy and the pressure of the transmission fluid and increasing the amount of heat the system generates.
When a vehicle experiences torque converter problems, it often starts to shudder at speeds between 30 and 45 miles per hour. The shudder feels like the car is driving over a rough road, even though it is on a smooth surface.
Damaged transmissions and torque converter clutches produce large amounts of black debris in the transmission fluid. Change the fluid, and check it regularly to determine if the problem continues.
A speed-stall test helps to determine if a vehicle is experiencing a torque converter problem. Always check with the vehicle manufacturer before beginning this test because it can damage the transmissions of some vehicles. Avoid performing the speed-stall test on vehicles with anti-lock brakes to prevent damaging them. This test illuminates the check engine light on vehicles with electronic monitoring systems.Learn more about Transmission
The cost of rebuilding the transmission of a vehicle can range from between $1,000 and $3,500 or even more. Costs vary greatly depending on the make and model of the vehicle and on the amount of damage to the transmission.Full Answer >
To change transmission fluid, jack up the front of the vehicle, open the transmission pan, inspect the old transmission fluid, check the gasket, replace the filter and add new fluid. The exact steps to changing transmission fluid depend on the make and model of the car.Full Answer >
The warning signs of a bad torque converter include transmission slippage and surging, partial loss of vehicular power, problems when attempting to switch gears and abnormal engine noise. According to Cars Direct, these symptoms may occur separately or simultaneously. Immediate service and converter replacement is the only way to prevent catastrophic engine damage.Full Answer >
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.Full Answer >
