eversince i bought my car, everytime i change from park to drive the car seems to move foward/ kinda twitch forward (while i have my foot on the brake) i dont know what it is, could it be a problem with the tranny?

 

your idle is up to high. Lower it and it should be smooth

 

More than likely your ideling high and your cars converter is kicking in a bit and loading the suspension

Its just the suspession loading, it does that on mine to

 

Its the idle. Lower it about half a turn and see what happens.
