New answers tagged shifting
the only way to reverse while the car moves is if you change from d to n then r but do not accelerate or the car will use its momentum and transfer that physical energy directly to the engine which will cause the transmission parts to suffer greatly (specially the clutch, with standard Automatic transmissions, not CVT.)
I'll assume you have a standard shift transmission. If this is the case, your problem lies with a bad clutch. You'll need to get it replaced to fix the issue. If this is an automatic transmission, you either have low fluid or your clutches/bands are fried, which would mean a replacement or rebuild.
