I've just changed mine on the RP (back axle) I last did it in the 1980s, and to be fair there was nothing wrong with the stuff that came out. The only time I've changed the gearbox oil was when I stripped and rebuilt it a few years ago (4 spd crash).
In both cases it's more important not to overfill.
