as far as I understand , it does not have a modulator. e4od are electronic. no vacuum shift modulator


On some of the older vehicles the vacuum modulator controlled the shift points of the transmission by using the vacuum supplied from the engine.


If a vacuum modulator has fluid in the vacuum port, it has failed and should be replaced.


Yes, check the vacuum line between the transmission and the throttle body. If you can see ANY sign of oil in the vacuum line, the vacuum modulator is leaking. Of course, all of that is dependant upon YOUR transmission having a vacuum modulator. Some do, some don't. Generally, they are quite simple to replace, so long as you keep everything clean.


There should be an o-ring where the modulator is inserted into the transmission. There should be no fluid where the vacuum line attaches, if so the modulator is bad.


Disconnect the battery (always disconnect the battery when working under the car!!!) Unplug the vacuum hose. Remove the retaining bolt. Pull out the old modulator. Slide in the new one. Replace the bolt and vacuum line. That's about it.


That transmission is electronic controlled. No need for a modulator valve.


Starting with the 1995 Ford Explorer model the transmission is ELECTRONICALLY controlled ( so there is no vacuum modulator )


To change the transmission modulator valve in a 97 Pontiac Bonneville you will first need to lift the vehicle off the ground. Then, remove the vacuum hose and the defective valve. You can then replace with new, and replace the hose.


The vacuum modulator is a small canister on the the side or rear of the transmission case depending on the model transmission.It is retained into the transmission by a clip that is retained to the case by screw or bolt.TO replace:Remove vacuum line from modulator, inspect line for cracks, damage etc.remove the screw or bolt holding the clip and retaining in the modulator.Inspect the new modulator to insure the "O" ring is in place on the portion that goes into the transmissioncarefully pull the modulator out of the bore in the case. At this point the transmission will probably leak some oilPush the new one in the holeRetain with clip and screw or bolt.Plug in the vacuum line


I assume your refering to the vacuum modulator which controls transmission shift points. Remove the vacuum hose from the modulator. Using a small screwdriver, turn the screw inside the modulator. It may take several tries to get it right.


There is a screw adjustment in the vacuum modulator port


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


Jack up and support the rear of the car to minimize fluid loss. Remove vacuum hose from modulator. Remove bolt and retaining clip from under modulator. Remove modulator by pulling straight out. Install new modulator with new o-ring, replace clip and bolt and vacuum hose.


Dodge transmissions do not use vacuum modulators.


That year model did not have a modulator valve on the transmission.


When the vacuum from the engine sucks in transmission fluid from the bad modulator and shows up as heavy blue smoke out the exhaust.


If this transmission is equipped with a modulator valva it will be on the frontside of the transmission. Pointing towards the radiator. Its a round canister with a vacuum line plugged into it.


A 1968 Plymouth Fury II does not have a Transmission Modulator as such. The throttle linkage on the A904 a A727 transmissions performs a similar function to a ( Vacuum ) Modulator .



assuming your talking about the transmission modulator...visually inspect the transmission and look for a vacuum hose from the engine to the tranny...
