    Any thoughts

    I have a 2000 Trans am WS6 automatic all stock. Every once in a while when beginning to accelaratefrom a dead stop the car jerks while changing from 1st to 2nd gear and sometimes is very smooth . Very sporadict happens at various accelaration rates.

    Is this tires related ? Transmission ? Differential ? Or Other?

    Maybe the Poly Transmission mount?

    Any thoughts are greatly appreciated.

    no, is more like rough change in gears coming from the rear end of the car.

    how could I tell if it is hitting the floor board. The sound appears to come from the rear end of the car sometimes is harder than others and sometimes is very smooth.

    u-joint is located on the driveshaft. one towards the front and one towards the rear. here's a pic of the rear one.

    I finally was able to look under the car today. I check the trans mount and looks solid. no cracks. Try to move it and it wouldnt budge. The same is true for the u joint and the drive shaft. Anything in particular I should be trying to pin point the problem?

    When was the last time you changed your fuel filter?

    In Socal, what with all the crappy gas running around, that's a long time to go between fuel filters. Just a thought...

    The thing is that it only does it when it shifts from 1st gear to 2nd. It is a sudden jerk where the wheels sound like they are skipping along with a loud thud. Sometimes is very smooth like new.

    I had the same problem. I just replaced my tranmission mount today and the problem is fixed. autopartswarehouse.com. Make sure thats the right part. One requires modification and the other is a direct bolt on.
