Needs Oil?
Hmmm...Hard shifting can mean many things.
Lack of oil is one of them, because a bushing is getting seized up...
But also, you might have an issue with the "SHIFTER FORK" - so do you have a Manual or Automatic - transmission?
IF it's an automatic, then that is a TCM/Actuator problem.
IF you have IB5 - 5-speed manual - start by taking that little cover off the transmission gearbox - and gently pry off the E-clip - and gently try to pry that metal bracket towards the front of the car - by about a 1/4 to 1/2 of an inch (or about 1cm)
So you can apply a simple auto oil to the bushing and shaft.
Press the bracket back in to seat it - do the pull and push to bracket to work the oil in to free up any stiffness - applying some oil to get the lubrication on the pivot shaft.
Once it's easy to pull-off and press on - then reattach the E-clip and put the gearbox plastic cover back on. You should be able to find 3-rd gear.
