I bought a 2000 xc70 today with 122k miles. The owner said it gets stuck in overdrive. I am looking to fix whatever problems this car has to get it going again. It is in good shape and runs well. I haven't induced any transmission codes in it. I plan on registering it tomorrow so I can take it on an extended test drive to see what happens. Any guidance would be appreciated. It goes into forward and reverse OK.
