ok this is how i checked, put it in first andleftit there, got up to about 25 let off the gas and letit coast down to about 15 or so and then touched the gas again and a huge THUMP. It comes from the middle of the car or so it sounds... Family issues make me short on cash so i dont need to take the car to the subie dealership for them to say 40 bucks to check it. So either i need advice on if the tranny mount is the problem or what... thankyou and advance, i want to order the part ahead of time then have them install it... that is why i am trying to determine what is wrong with mine.
