WTF is the modulator valve? HELP!!! QUICK!!!

Ray is right on the location Josh.

Here is how to change it. A lift would help but if dont have one just jack up the car and secure it with jack stands (duh). First thing go to the FORD garage and buy a new one before you take the old one out. When you find the vacuum Modulator on the side of the tranny, you will see a clip that resembles a Distributor hold down. It is secured to the tranny with one bolt above the valve. take the vacuum hose off the valve and hold out of it the way. There may be a little tranny fluid run out but its ok. take the bolt out of teh hold down clip and remove teh modulator. There will also be a little fluid run out when you remove the valve but once again it's ok. When you pull the old valve out you should see a small needle sticking out of the back of it. If the needle is there remove it and put it in the new valve. If its not there its still inside the tranny, if so reach up into the the hole where the valve sits and remove the little needle. Place it into the back of the new valve and put the neew valve in the hole. Replace the clip and bolt down. Just get it pretty snug there is a seal on the baclk opf the new valve that will hold the fluid in, be sure not to break off the bolt. Taping a hole is one thing but in the side of a tranny in a car is another. Check the fluid in the tranny when your done. Go ahead and buy a quart before you start cause youre gonna spill some.

My guess is that you are using a little tranny fluid but cant find a leak anywhere?????????? Also it is slipping a little between first and second, and when you first put the car in gear, or when you switch from reverse to ant drive gear after backing up. Am I right??????

Hope all this helps. This is the way I changer mine a few weeks ago and those were the symptoms.
