Newer models like yours do not have a modulator on the trans; they are computer controlled. If you are having shifting problems I would suggest you change your trans fluid and filter; that should clear up shifting problems if it seems to stick in a lower gear. I hope this helps you. Mark
That year model did not have a modulator valve on the transmission.
That transmission is electronic controlled. No need for a modulator valve.
It is on the passenger side of the transmission towards the back of it. It will have a vacuum hose hooked to it. There will be a small bracket with 1 bolt that holds it in the transmission. Do not loose the small pin that is inside of the transmission when you remove the modulator valve. You will loose some trans. fluid.
The 2001 Chevy Impala vacuum module can be found on the back of the engine. The vacuum module valve will be near the top of the engine.
If your transmission has a modulator it is on the side of the trans and it has a nipple on it for the vaccum line. I you. Mark
If your car has one, take the vacuum line to the modulator off and if there is fluid inside, the modulator is bad.
NO IT DOES NOT.
The factory transmission that belongs in that 94 model did not use are have a modulator valve. But to answer your question the line goes to any intake vacuum source. That year truck should have the 4L60E transmission in it.
as far as I understand , it does not have a modulator. e4od are electronic. no vacuum shift modulator
Defective modulator valve.
If a vacuum modulator has fluid in the vacuum port, it has failed and should be replaced.
That transmission does not have a modulator valve on it. It is computer controlled to a point.
