When my car is in park you hear nothing but when you put it into gear drive it starts making a clicking noise and as soon as I get to a decent speed 20 kmh you hear nothing but when I slow down or stop you hear the clicking noise and when I put it back in park it goes away
Are you referring to a light buzzing noise that lasts for about one second when you shift into drive or reverse, and when you come to a stop? That is the Transmission Computer cycling the shift solenoids on and off very quickly to soften the feel of the clutch engagement for comfort. It only applies the the four-speed overdrive transmission, not the three-speed. The four-speed will have a big "0" around the "D" on the shift indicator.
