when to change gearbox oil

[pomoz]

Gday all

Its a simple question
Thou if you dont ask you dont find out...

I am in the process of changing oil and oil filter ..

Done .. the oil filter change was a bit of a challenge .
Thou that part is done.....

When do i change the gearbox oil?
Seeing that i have the car panel off and the car is over the pit...
The car has only done 400 odd miles since the last gearbox change or 18 months ago .. bit of slack driving eh .. though not being here and being in England .. what do you expect...

I as yet cannot get my hands on Redline MT-90
So will put the same gearbox oil as Lotus recomends
Mind you car has done 63k miles .. no engine build .

Suggestions please
Shame not to do it .. consider the cheapness of the gearbos oil

Thanks

You can probably find the frequency by searching this forum. As to a source for MT-90, it's available at this link. Can't say what shipping will cost from Akron OH to the U.K.
