Gearbox oil for T5

[Shounak]

Just wondering if anyone knows the type of gearbox oil recommended for a T5 and how much of it is required for a refill from dry?

Cheers

takes about 2 litres for memory and from factory your supposed to use a 20W90 or something.... or 30-75... its really heavy, but its crap.

Use an ATF.

aZk.

I think 2.5 ltrs from dry, and i used to use castrol vx90.

dont use atf for pre vr t5's it wears out the syncros. do a search on sc in the diff/trans section.

What if all the syncros have been replaced?

I did do a few searches over the net and it does apparently cause premature internal wear due to it being much thinner than gear oil.

If you have new synchro's, it will just wear them out faster. So I'd say you should start learning the double clutch.

A 75w-90 should work just perfectly. I'm thinking the full synthetic one from Castrol.

They go much better with a full synth whatever you choose

Redline... Yes its expensive, but it seems to work well.

run ATF, standard gearbox oil is to thick. many people have complained about problems with the T5 that have gone away when changing to ATF. i've run it in mine (VN as the owners manual says) for years without a problem. holden also specify you add 150ml's of lubrizol with the ATF.
