dear sir
i have a corolla 2007 with only 3000 miles,after staring the engine ,when i press the brakes to change the transmission from P to D there is a clicking sound in the transmission box,like a click then dissapears,present only when i press the brake and the transmission on P,i could change easily to D,pressing the brakes when transmission is on D or R doesnt prouduce a sound. is this sound normal or is something wrong?pls advice thank you sir

This is normal with most auto transmission cars.

that is the sound of the transmission interlock disengaging to allow you to shift out of park. this is the design of the auto trans system to prevent you shifting out of park accidentally if you don't mean to.
