I have never had this problem so i dont know what exactly this is but im guessing my tranny is slipping. i go to Drive and i give it gas and it just revves like its in Neutral so i go back to park and into Drive again and then it catches and it goes...anyone care to help? i know its a noob question but i dont have much experience with this one haha as all my vehicles before this one have been standard. and anyone care to quote me a price on a 4L80e?
