Driver's Seat Loose

Hi,
I have a 2002 Tahoe Z71.
The driver's seat is loose.
Whe I stop it moves forward and when I accelerate it moves back.
Although it is just slightly, it is a pain.
I have tried to tighted the seat to the frame with the four corner bolts, but to no avail.
There are bolts holding the seat to the track, but they are in such a narrow opening, it is nearly impossible to reach them.

Does anyone have any suggestions?

Thank in advance.

I have on 01 and it's the same way since 30,000 miles (85,000 now). I mentioned it to 2 differrent dealers and they said nothing they could do. I looked into tightening it myself also and saw the same thing you did. Actually mine seems to be loose in the bracket area that connects the bottom to the back. The good news is that in the last 55,000 miles it did not seem to get any worse so I kinda learned to live with it. I am curiuos also to see if anyone solved this problem.
