Don't know if there's such a thing as gearbox flush.. If you can afford it, buy two lots of oil, replace the first lot, drive for some distance, then replace with the final lot. That should get rid of most crap.

Chances are you will have a magnetic drain bolt on your gearbox, if you take it out to drain the gearbox you will notice that it will have metal particles stucke to it so obviously give it a thorough clean before you put it back in and no need to flush, just drain it while the oil is warm, ie. after a drive.

Some places have machines that do actually flush the gearbox,

around a hundy to have it done.

I'm pretty sure those machines are primarily designed for flushing automatic transmissions.

True, I was making an assumption.
