Transmission Problems. Please Help.
A while back I was driving my '00 TA WS6 on the highway. When I started to slightly accelerate, the engine just revved and the trans seemed as if it came out of gear, but it still felt like the clutch was somewhat engaged because it was still barely accelerating. This started to happen about 2-3 times every time I drove the car. The rest of the time it acted perfectly normal. Well, I ignored it, hoping it would go away. A couple months later the 3rd and 4th clutch fried, so I took it in to a tans shop and they rebuilt it completely. I got the car back and it was still doing the same thing. So I had a talk with one of the mechanics and he said he had no idea what was causing the problem. He told me to wait until something completely broke. So a couple of weeks ago, with only about 10k miles on the new trans, the 3rd and 4th clutch went again. Luckily it was still under warranty so it was free to fix. I talked with the head mechanic this time and he said that all cars with this type of trans have this problem. He said to keep it in 3rd when in the city because when the car is at about 40, it has trouble deciding to go into overdrive, and he said to use cruise control when on the highway (which I can't because of traffic). So I try to keep my foot on the throttle as much as possible. Unfortunately, it still happens. I know it can't be the trans because it is brand new. I thought it could be the computer so I had the dealership update all of the available software to no avail. So, here I am clueless as to what to do. To summarize the problem, it only revs when it's in 4th and I give it more than 1/4 throttle. The clutch is trying (like, on a manual, when you have the clutch pedal partly depressed). If I slowly accelerate and it starts to do this, I can give it as much gas as possible and it still just revs. If I quickly give it throttle it will usually downshift and work perfectly. Any help would be appreciated. I don't want the clutches to go again and this time not be under warranty.
