Any thoughts

**blacktransamws6** · 05-06-2006, 03:38 PM

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.

does it sound like its hitting the floor board?

**blacktransamws6** · 05-07-2006, 09:03 AM

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

last time you did a transmission fluid and filter change?

**blacktransamws6** · 05-08-2006, 04:10 AM

About 20,000 miles.

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. Mine is going bad. I can hear it knock when i take off.

**blacktransamws6** · 05-08-2006, 06:45 AM

Where is the U joint? How can I tell if its bad? Thanks

**mrr23** · 05-08-2006, 12:47 PM

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

What should I be looking for in the U joint and in the Tran mount?

**blacktransamws6** · 05-10-2006, 03:42 PM

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?

**blacktransamws6** · 05-11-2006, 03:36 PM

about 20000 miles ago did it with the trans and differential change

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.
