1999 Honda Accord Cpe - Hesitates when shifted

My Honda Accord when I put it in reversely hesitates than goes in , put it in drive and the same thing, what could it be??

You didn’t say but I’m going to assume the hesitation isn’t happening because the engine isn’t getting gas. My offhand guess is transmission trouble. The fluid could be low, the transmission could need maintenance in the form of a fluid change, it could be something worse. You need to have the car looked at by a qualified mechanic. If it is the transmission, they can recommend a shop.
