Looking for some advice on what could be wrong with my car. I’ve had it hooked up to a computer the code was shift solenoid B malfunction (electrical error) P0758. After the solenoids were replaced, I drove it the next day and the AT light kicked back on and my car started kicking when It would switch gears and wouldn’t go into third. Same problem before I changed the solenoids. Computer is reading off the same code. Any idea? Sometimes I can drive it if I rev slowly but when I make stops it likes to mess up. 2010 Mazda 3 2.5L
