I just bought an ‘03 Protege5 about a week ago and am having some strange issues. When I have the AC on, and am accelerating hard to get on the freeway and such, it will randomly downshift from 4th to 3rd once I’m at speed (65-70) and rev up to 4K and get stuck in 3rd, battery light comes on, subwoofer shuts off, and air blows hard. Only way to get out of that gear and back into 4th or any gear for that matter, would be to let off the gas, shift to neutral and back into drive. This will happen many times in my drive. I don’t have this problem when the ac is off. Any help would be amazing!
