2000 Volvo S80. Transmission failure with only 109,000 miles. I have always done the required maintenance and service on the vehicle, which included a transmission flush in 2003. I had no prior warnings, no slipping, nothing. The transmission fluid is clean, at the level it is supposed to be at, no leaks, and no warning "check engine" or "transmission" lights came on. My mechanic said that due to the sudden failure with no warning, it is most likely something internal that just broke and that I have to get a new transmission.
