if its an automatic then you are screwed and will need a rebuild. or a new tranny. if it's manual, it could be in your shift assembly, or in the cogs, or in in the synchronizers. if it is an automatic, try getting the tranny serviced, flush the fluid, then maybe put some marvel mystery oil in it. put that in it anyway
