Hey, earlier this evening I meant to throw the car into Drive but it went into reverse and i slammed on the gas. It bucked backwards a good 10 feet and then stalled. Now when its running, idle or low gas it hovers around 400-600rpm and feels like its going to die. When I give it a little gas in drive, it barely moves. I hear the engine making noise but the car barely moves. When i give it a little more gas (a little over half throttle) it finally kicks in and moves at a normal pace. Did i rape my tranny or rear end? or is it something else.
