Your synchro;s are probably going out. You will notice this at higher rpm's like when moving and whatnot but sitting still it will go right into gear. I would drain your fluid and see if it has any metallic color to it and put fresh fluid in. This might help for a little while but if the fluid comes out with some shiny little spots that migth look like metal then there is no getting around it.
