My allroad has a TIP (manuals are hard to find over here too) and the car has 165k miles. Every once in a while there will be a hard shift but other then that it's been good.
That being said they are known to have weak torque converters and a seal inside is known to fail. When this happens it will need to be pulled and rebuilt which could cost a couple thousand. If/when this happens with mine I'm going to see if I can source a 6sp swap since it will be only slightly more expensive.
