    Re: transmission modulator

    Its a round metal "can" with a vacuum hose on the end sticking straight out of the transaxle (probably under the air box), pointing towards the front of the car.

    Here's a pic:

    Its the one on the left. The "golden" part would be inside the trans, the grey can sticks out and the vacuum fitting goes out the little tube.
