Shift into low?
 

I have a 1994 Cadillac SLS with the 32 Northstar Engine 32 valve 4.9L V8. What could causes it to be driving along and suddenly shift into low and also cause the temp, avg mpg, and fuel used to go blank?

I made a mistake, it shifts out of OD not down to low gear. It also cause the range to go blank.
