Hello I have a 1993 Lumina and I am have a prob. with we got used from a dealer as is and we got one week ago and now we are having a realy bad prob. with it when you go down the road it shifts fine untill you get in to high gear and then it starts to bogg down and you have to let off the gas to let it drop down a gear so it will start running ok what could that be please help!!!!
could it be the converter or some thing else
