why would it be dooing that i have 167,453 miles
when i drive down the road my shifter nob goes up and down when i giv it gas on 1994 Chevrolet Camaro
Since the engine and trans are bolted together when you press the gas the torque is transfered to the trans as it should be. So to answer in plain terms its the torque causing it and some amounts of movement that you describe are normal. Have the engine and trans mounts checked if your concerned. Based on the miles they may need replacing by now.
i figured it out it was the trans mount thanx alot im looking for a body kit do u recomend any sites to buy from
