I'd bet grommets. The one on the shifter is pretty easy. The one on the transmission is a bear. I just replaced mine. I ended up taking the lever arm off the trans to putting the grommet in. The lever arm only goes on one way so you don't have to worry about getting it on in the right position. There is a 10 or 8 mm bolt holding the arm on the trans. Also a cup of nearly boiling water helps soften the grommets to make them go in much easier.
