With a very annoying gearbox slip and after numerous oil flushes, I would like to change the gearbox filter before opening up the box.

Am I correct that the only way to access the filter is by removing the gearbox or is it possible to remove the filter with the box insitu?

gearbox remove is the only way to access the filter actually
