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
Manual transmission systems have the potential to improve fuel efficiency, enhance performance, and may reduce the average price of a vehicle Manual transmissions can tremendously improve the performance of cars, particularly those with smaller engines. They are considered by many drivers to be more fun to use, and may reduce gas consumption.Full Answer >
After the engine, the most expensive repair for a vehicle is the transmission. With absolutely no care or maintenance, an automatic transmission can last as little as 30,000 miles. With very slight maintenance, the transmission should last well over 100,000 miles.Full Answer >
Changing the transmission fluid in a vehicle should take place based on the manufacturer's written recommendation, which ranges from 30,000 to 60,000 miles for manual transmissions and 60,000 to 100,000 miles for automatic transmissions. More frequent changes do not harm the components.Full Answer >
Overfilling an automatic transmission causes the fluid to foam, leading to erratic gear shifting, oil starvation and transmission damage. Overfilling a manual transmission causes the fluid to leak from the vent and the gear trains to slow down when the clutch is depressed, leading to gear shifting problems.Full Answer >
