I checked the transmission fluid, and it was very low. I added fluid, and although there is still some transmission slipping, the problem is not nearly as bad as before. There are still odd electrical things going on intermittently. The last time I drove the car, it didn't seem to have a care in the world.
We connected a CAN scanner to the car today. This is the only thing the scan reported.

Catalyst system efficiency below threshold bank.
What steps should I take now?
