Just an interesting observation for the original poster. I sold a Volvo XC90, a really nice vehicle by the way, to a friend. Six months later, he got a transmission warning message. Dealer checked it out and told him it needed a new transmission for $7K or so. Thing was driving and shifting perfectly, and I felt really bad about it, but we decided since it was driving OK, he would just ignore the light and see what happened.

Two years later, the transmission fault light is still on and the XC90 drives and shifts perfectly. Clearly there was no significant problem with the transmission enough to warrant a new transmission.
