Should I bother changing manual gearbox fluid?

[ThatsGuy]

Car has 130k and is 8 years old now.

Gearbox is fine but a bit clunky...Holden say don't apparently, some people say do....how long does the at fluid they put in really last...

Or am I better off leaving it while it's working fine?!

change it, the filled for life is a crock of ****, ring some local trans joints and ask em if you want to confirm it either way

I've never understood why they don't want it changed, surely the oil gets contaminated over time?

The way I look at it is, changing the oil can't hurt anything and for fifty-odd bucks worth of oil every few years it's cheap insurance!

But the biggest incentive for me would be getting some early warning of a future problem by checking for metal stuck to the magnetic drain plug, catching that early could mean the difference between a new set of bearings or a whole new transmission assembly when it detonates?

It'll keep your synchros good if you do (or as good as they are no anyway).

no oil is that good!!, have done mine 3 times since buying it, every 50,000klm box is nice and smooth (well as smooth as these box's can be!)

like i always say oil is a wearing part and needs replacing just like everything alse, should check your diff oil too and change it if need be

My box feels 100% better after putting Penrite pro gear in it. 2nd is still a little notchy but it is so much better than it was.

It's not the oil that wears in a gearbox, it doesn't get hot enough to break down. But it suspends all the bits that wear off the moving parts, this is why you should change it.
