It's been quite a while since I've noticed this sound coming of my automatic transmission when I accelerate then I release the gas pedal. As soon as I'll take of my foot of the gas, the transmission makes a ticking noise. My father is an ex-mechanic and he told me that's it's normal and that it was a slack that I have in the transmission and I shouldn't worry too much about it, but it's making my brain work.. Any ideas what to look for or what could be the cause? BTW, a have a 2003 Honda Civic LX Coupe with 110 000 kilometers.. Thanks!

 

Anyone?
