when i drive at about 30 to 40 my rmp meter goes up and down a few rmps as if looking for the right gear or rmp level if i give it gas it goes aways or i turn off the traction control. a few people tald me is the trasmission computer that needs to rempaing or a censor any ideas?

It's where the transmission "hunts" for the right gear, but actually your torque converter is worn. The only thing to fix that would be a rebuilt transmission. One way to "fix" that is to put the gear selector into tip mode when you are driving over 35mph. That's interesting you're getting that problem though. I thought only the A8 transmission had it. How many miles are on your vehicle?
If you would like tons of information on "hunting", I suggest you search the D2 A8/S8 forum using <font color="blue"><b>80919</b></font> and <font color="blue"><b>22012</b></font> in the <b>Account id:</b> filter and <font color="red"><b>transmission hunting</b></font> in the <b>Search for:</b> field

Either way, try putting it into tip mode when driving between 30-40 mph and see if that helps.

how do i put it into tip mode?

there is an area to move the shifter over marked with "+" and "-" when the shifter is in "D". So, when you are driving between 35-45MPH, move it over and it should stay in 4th gear.
