How does it work?
A few days ago I posted a question and asked about how to make my AUTO transmision perform better. I had a fewhelpful answears, (THANKS A LOT BY THE WAY), but I also want to know how they work.</P>
Stall converter: What exacly is it, how to install it, what makes it perform better than the stock, What to expect after installing one?</P>
Shirt Kit: same questions</P>
Thanks a lot in advance</P>
</P>

The stall converter allows you to hold the brake and push your gas pedal up to the specified RPM for your aftermarket converter, getting you closer to RPM's at which you make sufficient power to get you off the line as fast as possible.</P>
Say you buy a 3200 stall converter: When brake standing, your rear tires won't spin until your engine's rpms are at 3200 rpms...as far as installing one, I'd leave that to a shop to do...</P>
The shift kit will enable your transmission to shift quicker and much more firm. </P><edited><editID>Dan02GT</editID><editDate>37984.8206597222</editDate></edited>

A torque converter is a type of fluid coupling, which allows the engine to spin somewhat independently of the transmission. If the engine is turning slowly, such as when the car is idling at a stoplight, the amount of torque passed through the torque converter is very small, so keeping the car still requires only a light pressure on the brake pedal.
If you were to step on the gas pedal while the car is stopped, you would have to press harder on the brake to keep the car from moving. This is because when you step on the gas, the engine speeds up and pumps more fluid into the torque converter, causing more torque to be transmitted to the wheels.

The housing of the torque converter is bolted to the flywheel of the engine, so it turns at whatever speed the engine is running at. The fins that make up the pump of the torque converter are attached to the housing, so they also turn at the same speed as the engine. The cutaway below shows how everything is connected inside the torque converter.
he pump inside a torque converter is a type of centrifugal pump. As it spins, fluid is flung to the outside, much as the spin cycle of a washing machine flings water and clothes to the outside of the wash tub. As fluid is flung to the outside, a vacuum is created that draws more fluid in at the center.
he fluid then enters the blades of the turbine, which is connected to the transmission. The turbine causes the transmission to spin, which basically moves your car. You can see in the graphic below that the blades of the turbine are curved. This means that the fluid, which enters the turbine from the outside, has to change direction before it exits the center of the turbine. It is this directional change that causes the turbine to spin
In order to change the direction of a moving object, you must apply a force to that object -- it doesn't matter if the object is a car or a drop of fluid. And whatever applies the force that causes the object to turn must also feel that force, but in the opposite direction. So as the turbine causes the fluid to change direction, the fluid causes the turbine to spin.
The fluid exits the turbine at the center, moving in a different direction than when it entered. If you look at the arrows in the figure above, you can see that the fluid exits the turbine moving opposite the direction that the pump (and engine) are turning. If the fluid were allowed to hit the pump, it would slow the engine down, wasting power. This is why a torque converter has a stator.

Think of it like a top, or a gyroscope. Your gas controls the engine, which controls a "fan" that spins fluid through another "fan" that is attached to the engine.
The higher the stall, the more your engine can spin up before it catches. However, go too high, and it won't be streetable<img border="0" src=smileys/smiley2.gif border="0">
