"Throttle Valve or Modulator
To shift properly, the automatic transmission has to know how hard the engine is working. There are two different ways that this is done. Some cars have a simple cable linkage connected to a throttle valve in the transmission. The further the gas pedal is pressed, the more pressure is put on the throttle valve. Other cars use a vacuum modulator to apply pressure to the throttle valve. The modulator senses the manifold pressure, which drops when the engine is under a greater load."
This if from howstuffworks.com. Im curious if any of you have any thoughts on this? Do tauruses use the Throttle Valve or Vacuum Modulator? If they use a Vacuum Modulator which senses manifold pressure to actuate the transmission wouldnt a forced induction application, which would often eliminate manifold vacuum states, confuse the ATX? I know DMX has forced induction and he hasnt even really done any mods to his ATX...Anyone have any thoughts?
