Transmission Trouble
 

Can anyone give me some advice on what might be wrong with my 98 Beetle 2.0L 5spd man. tranny, it just started giving me trouble, it has about 61k miles on it. I'm having a hard time getting it into 1st and 3rd gears, it doesn't grind I just have to push extra hard to get it into gear, I tried changing out the gear lube, but no help, the clutch dosen't slip at all but I'm thinking about changing it anyways just in case it is warped. Any help would be greatly appreciated.
