Hi. my fiat bravo hlx has become sick. my gearbox all of a sudden feels like it has porridge in when i change gears. the gearbox oil hasn't been changed in over 3 years (since i owned it).

does anyone have any idea what it could be.

i have 30 mins before i leave work and would to love to know if it will make it home or to the garage

gearbox oil wont be the problem, unless it has ran out of oil.

does it feel the same when engine switched off?
