Need help! My mmc glxi Automatic transmission has a prob. Everytime I'm on drive and my car is running, sometimes it doesn't react when I step on accelerator. D tumatakbo pag nag-accelerate ako. What I do is shift it to park or neutral then shift it back again to drive tpos tumatakbo na. It seems the transmission slips to neutral while on DRIVE mode. Advise please. Thanks!
