Torque Converter and Torque Repair Guide for Dummies

Torque converters have 5 specific functions for a vehicle:

· A converter provides multiple torques generated by the engine.
· It serves as an automatic clutch that transmits engine torque to the transmission.
· It absorbs torsional vibration of the engine and drivetrain.
· A transmission torque converter smoothes out the engine's rotation.
· It drives oil pump of the hydraulic control system.

Transmission fluid provides the converter the high performance power to do its job for fluid coupling. A torque converter has three major components: the pump impeller, turbine runner, and the stator. Any damage on these three converter parts means immediate torque repair.

Torque repair for this parts require some information on their individual functions. First off is the converter impeller. The impeller guides the fluid throughout the vanes and out onto the turbines. As it increases speed, the force it creates gets the fluid moving towards the turbine. When the impeller gets rusty or becomes simply worn out, torque repair vendors would generally replace the part for better and higher performance. This is the reason why fluid for the converter has to be regularly checked so that everything is well lubricated to move smoothly.

The turbine is an essential component of the transmission torque converter. The input shaft of the transmission is attached by splines to the turbine hub when the converter is mounted to the transmission. The fluid that is transmitted by the impeller is caught by the cup-shapes on the turbines, which transfers torque to the transmission input shaft. Damage to this major converter part usually means total replacement of the whole torque converter.

A non-major but essential converter part is the torque converter clutch. It is an electronic clutch that will engage the engine and drivetrain 100%. Although the torque converter clutch is not part of the engine, it can make the car feel like the engine has a problem. The torque converter clutch is also known as a lock up converter. The lockup clutch has many purposes and is part of the transmission. A regular converter in an automatic transmission is made to slip at idle so that the car doesn't move. As the accelerator is pressed the RPM's raise and the torque converter will start to lockup or engage. When the converter engages the car will move. Even though the torque converter is engaged it never completely engages the way a manual transmission car clutch will. It will always slip a little, which is not very efficient. This is why a manual transmission car gets better gas mileage and has more power than an automatic transmission car. High performance should be expected of a converter is the clutch is also well kept.

The stator is located between the impeller and the turbine. The vanes of the stator catches the transmission fluid and redirects it so it strikes the back of the impeller which gives it another boost or torque. Stator clutch seizure, a common problem for this converter part, requires either complete torque rebuild or you'll have to install new torque converters. If you experience stator converter breakage, then the vehicle won't be able to move at all so have this part checked in such circumstances.

Ameritorque is a torque converter vendor that provides torque converter installation, torque rebuild, and torque repair for all your converter needs. They are also torque remanufacturers that rebuild old converters into functional ones. They service the areas of Tampa, Brandon, St Petersburg, Clearwater, Lakeland, Hillsborough, Pinellas, Pasco, and Polk.
