Hi all sifus. I'm facing big problem with my ride. I'm driving 2006 Mazda MPV(JDM version of Mazda 8 but came with MZR DISI 2.3T turbo engine as standard, the engine is same as Mazda CX7's engine). The problem is when I drive the car for a journey more than 100km, the gear will kick to "neutral" if I try to accelerate e.g when overtaking or going up hill. When this happened I need to release the pedal then press it again and everything will back to normal. This will happen at least 3 to 4 times in a 450km journey. As I remember this problem only happened in daytime especially from 12pm to 5pm. I've changed the ATF but result still the same. I've diagnosed the car for two times in different workshops and there's nothing wrong(according to the diagnostic tool). Any opinion sifus?
