Hello, my mother drives a 2002 v70 with about 107,000 miles on it. She loves the car, but most maintenance happens when I come home and push her to make appointments or bring the car for an oil change. The timing belt was recently replaced along with the major service that should happen just over 100,000 miles. <p>I know that these transmissions tend to go bad. A month ago a woman came to our tag sale and told us her husband is a volvo dealer and that we need to get rid of our car before it hits 100,000 miles because thats when the transmission goes bad. Where it is right now the car still shifts smoothly, with a very rare slightly abrupt downshift, which I think might happen because her neighborhood is a bunch of steep hills.<p>She got the transmission software upgrade at least a few years ago. I don't know if her mechanic flushed her transmission fluid at her last service or not, even though I told her to make him do it. <p>What are some tell tale signs that the transmission is going, what can we do to prolong the life of it, and are these cars worth holding on to? We've had a number of 240s over the years with over 200,000 miles on them, and she wants to keep this car forever, and so far it has always ran perfectly (never a CEL), but I just want to make sure it is worth it.<p>Thanks in advance for any advice you can lend.
