what is the problem?
Two weeks ago, odometer dial goes blank, RPM needle jumps. After that while driving, car moves slowly while foot is on accelerator, seems like accelerating has no effect, and AC stops working temporarily. after a while car works fine and AC works good again. This week, transmission check light flashes, car takes long time to change gear and gear changes with a jerk and car check engine light flashes, AC does not work after a while.
