Oooookay, here's my problem. I have a '01 Ws6 automatic. Whenever I accelerate just enough for the overdrive to kick in, all I get are my RPMs going up to about 4000 and alot of restriction as if she doesnt wanna kick in overdrive. When this occurs, I shift down to 3rd to allow my car to kick into overdrive. I had the transmission serviced about 6 months ago, had both cats replaced, cleaned my K&N filter, cleaned my MAF sensor, all 4 O2 senors replaced and oil changed. Can someone direct me into the direction I need to go to solve my problem...
