Transmission went bad in 2008 and now the light comes on and I need a new transmission.
How often does the transmission go out? on 2005 Volvo XC90
There's no magic mileage when they fail, could go at 30K or 200K, you never know. Be sure to maintaing the fluid properly, I suggest a complete flush of the system every 30-40K miles, and keep the software updated in the transmission control module.
