My Mazda Protege LX did the same thing, especially when it was hot out. I eventually found out it was a loose wire behind my overdrive switch located in the shift column. The overdrive button pops right out with a tight grasp and a little tug. See if both wires are still connected to the switch.
If the overdrive switch is turned off then the car will not go into overdrive. As it is not in overdrive, then it will not downshift out of overdrive as it normally would. It also will not shift to 3rd gear above a certain factory preset speed. Turn th overdrive on and see if it operates normally.
where is the thermostat on a 1999 mazda protege?
was wondering where the inertia switch is on a 1996 Mazda protege
