It's possibly from a sticking brake that is making the car's computer sensor think that you're slowing down, therefor down-shifting. I just got a 97 legacy wagon with similar problems, a friend pointed out that my front left brake was hot after less than two miles of driving and said that this could fool the computer. I am broke and can't go to a mechanic yet, so I don't know if this info is correct or not. I hope I'm not steering you wrong, good luck with your problem.
Seismic shifting is the shifting of the earth's crustal plates, causing seismic activity.
The soil in the Australian outback is high in iron. When iron comes into contact with air it rusts causing the soil to turn red...
The shifting in tectonic plates causing pressure making said quakes
Automatic transmission shifts can be related to fluid temperature and some vehicles also have sport style settings that can change shift quality. If the shifting is irregular and causing unusually high engine speeds this could be a symptom of transmission gear slippage. Gear slippage can result in transmission damage, and should be checked as soon as possible. Automatic transmissions are complex systems, and their overhaul/replacement can be very expensive repairs.
Try changing the fluid If that doesn't help may need a rebuild
