Converter? How does it work? I don't really understand how the converter works. I know that it helps the transmission during shifts or in between shifts. Also, does putting a higher than stock stall speed make you feel like you are driving around in 3rd gear?
Any info would be great thanks.

Not entirely correct, it is an essential part of the drivetrain that moves the car.

There is a difference at part throttle. Expect the throttle to not be so jumpy at very light throttle. For example, rather than taking about a half inch of throttle to get to 60 over a period of 15 seconds, with the stall it will take more like a full inch or even a hair more to accelerate at that same rate.
Here is a little more info to add to the great link posted above...

Its real simple though. Think what would happen if you took two fans and faced them at each other only a couple inches apart. Now you ONLY turn on one fan.............what will the other fan do? It will start to spin from the wind blowing from the other fan.
Well, a TC works the same way except the fan blades inside the enclosed case are blowing/moving fluid.
The TC is bolted to the flywheel so it spins no matter what, if the engine is running. At the same speed as the crank shaft. Thats why you can apply very little brake pressure when sitting still in "drive" and the car won't move. The converter is spinning and its trying to spin the tranny, shaft, axle and ultimately the tires, but its easily overcome by applying the brakes. So when you lift your foot off the brake and hit the gas pedal the converter spins faster, swirling the fluid faster, which makes the tranny spin and then the car moves. Liquid cannot be compressed, for all practical purposes anyway, so when your tranny's converter is full of fluid its pretty tight in there when the fan blades are swirling the fluid.
My explanation anyway.

Dexron 3 with Mercon!
NO SYNTHETICS!
While synthetics can take more abuse and heat, I highly recommend not using them as they run a lower viscosity and simply can't hold clutches tight enough either in the converter or in the transmission.
