    Hey guys, been just lurking on here a lot lately but in need of some thoughts. I had my mechanic replace a broken trans mount a couple days ago. Got it back and it was grinding the driveshaft on the body of the car. He put it up on the rack again and next day he put 1 inch spacers in rear springs to lift body to keep driveshaft from rubbing. Didn't work but it didnt grind on interstate home. As soon as I start going from stop it grinds again. Any ideas? Thanks.

    You need pics.
    I'd get some ramps or jack it, and get some pics of the trans brace.
    No one can help, until they can get a look at what is going on under there.

    My first guess would be that the mechanic used the wrong mount or modified the oem mount in some funky way.

    Take it to a competent mechanic and have him bill the first guy. Not sure how you can **** up a trans mount replacement but I've given up on being surprised by dipshits a long time ago...

    I think I will take my car to a more experienced shop who deals with not stock cars.

    Mount should look like one of these.

    Did the bill say what part number replacement they used?
    And did you get the original one back?

    Make sure you stay oem rubber on the trans mount.
    The trans mount should not be stiffer than the motor mounts.

    If they used a 96-98 gt (t5) mount, they may have had to drill out the bolt holes to make it fit:

    These mounts all work
    Fits 1979-1995 Ford Mustang 5.0 - All Transmissions
    - Fits 1996-1998 Ford Mustang Cobra - T45 Transmissions
    - Fits 1996-1998 Ford Mustang 3.8 - Auto & Manual

    Lastly. See post #6.
    Your mount kinda looks like this one..to me...like a gt mount...the wrong mount

    I will check it later. He said they compared them but something still isnt right. The mount was rubber so it may well be a wrong part.

    Looks like the exhaust needs to be adjusted.

    Looks like its rubbing on the parking brake bracket. Did you check to see if its bent? Mine did this back in the 90's when a cable went bad, had a similar Mark on the DS.
