Hi everyone, could somebody help me out, I have a seat altea xl, its an automatic, previously I have had no problem with it, I drove to work absolutely fine, no warning signs or strange sounds, I parked up for the day, as I came to drive home it started up fine but as i pulled off it seemed to be slipping gears and revving high, I parked it up when I got home and rang the garage, they told me it could be low transmission oil, they quoted me £2000 to fix because they said its a cancelled unit and they would need to take th clutch out before they take the unit out to get to the gear box oil. Dos this sound rite
