Transmission problems on 2001 Volvo V70 XC

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
I just bought this car, and now I find out the transmissions go out. It has 68,000 miles and I don't know if I should keep it. Is there a way to prevent transmission failure?

There are a few things you can do. Go to a Volvo dealership and see if you can get a VIP warranty. It is an extended warranty from Volvo that is very similar to the Volvo warrant. You may have too many miles but I'm not sure. While your there, have the software updated in all the control modules in the car. And last of all, flush the transmission fluid every 30,000 miles. If you don't have service records, then have the fluid checked and flushed if it is dark or smells burnt.
