Automatic Transmission Control Module problems of the 2000 Saturn SL

Interior overhead sagging above dome light, tried to have dealer fix (same condition after "repair"). Traction control button failed, had to be replaced. Ash tray light failed 3 times, dealer replaced. Ventilation blower only works on high speed - all other speeds burned out over 2 weeks (could smell electrical burning). Remote control works half of the time, no improvement after dealer replaced batteries, saying "white film" was a known cause of remotes not working. Change oil light came on 1000miles after last oil change, coinciding with fan blower burning out. Had to replace all 4 tires because of irregular wearing on rear and premature alignment drift on the front. Brake dust is excessive - front rims always coated black from dust. Some hesitation when automatic is shifting gears. Oxygen sensor replaced after 4 trips to the dealer to determine cause of "service engine soon light" coming on while accelerating. Adding 1liter engine coolant per month - no leaks noted under vehicle.
