    Replacing gearbox oil

    Hi guys, since my warranty is out, I am trying to save $ by going to a 3rd party mechanic.

    What's involved in replacing the gearbox oil? Any special instructions?

    Thanks!

    Thanks Jmac, (and to kevnii)

    ML90 is in. Took about 1.8 bottles. I still have one bottle spare for top up later if required.

    Only driven 30km so far. The shift feels smoother.

    Yet to see an improvement in sound, but will see. My l4000km fluid was brand new looking. No particles on magnet.

    You will have to give the oil at least 200 - 300 ks to coat all the nescessarys mate

    I'm looking to change my gearbox oil. Redline seems like the way to go.

    I don't have any crunching, but am looking to add a little smoothness to the changes.

    Seems the MT90 or MTL are options, given my mods and possible trackwork (minimal) is there a reason to go one way or another? I think there was another Spec choice:

    I've read people using 1.8 or 2.1 bottles, should I get 3 to be on the safe side?

    Use MTL. MT90 is slightly heavier and is good for older gearboxes with more wear/kms than yours probably has (ie mk 4 Golfs etc). The bottles hold one US quart (.945 litres) and Polo boxes vary a bit in capacity, but you'll need at least 2 litres. So get 3 bottles.

    Also, slightly overfill the gearbox. The volatile components in Redline tend to evaporate over time, and this makes sure the level stays high. Do this by raising the front pasenger side of the car, which raises the gearbox filler hole on that side above dead level. A brick between the front tyre and the garage floor is about the right amount of lift. If you're doing it yourself it also gives a bit more room to get under the car.

    The best price I've found for Redline stuff in OZ is www.performancelub.com/. This also has a link to the manufacturer's site with lots of tech info/specs etc.

    Agreed, MTL is the go for the 02R. Mt90 for the 02M. For smoothness Noone cant go wrong, 200- 300 ks to let the stuff wick in but im sure on the 1st drive you will notice the difference, i say this with confidence.

    Cheers, will order.

    Can anyone assist me in where the drain plug and filling point are? Can this be a funnel and hose job?
