Hey guys I have a 2008 tiburon gt and am having transmission problems and I'm debating on weather or not I should just drop it off to the shop and have to rebuild it or if I should flush and replace the filter and hope that works for the long run or at all...when the transmission is cold it will go into reverse neutral and park but when you go to put it into drive it does nothing...the display on the dash even stays blank bt if you rock the shifter a bit sometimes alot it will go into gear. Once in gear when you go to take off you have to feather the throttle to get it to move again..the car also has "bump shift" and even trying to use that it still won't go into gear you have to get it to show up drive before the bumpshift will work. The car is an 2.7 automatic and the problem just cam out of no where...also notice a couple spots of trans fluid once or twice but not recently thanks for the help
