The gearbox has never been sealed for life but close to it - 250,000km or 10 years or earlier in arduous conditions such as commuter driving, towing etc.

To do a proper flush the gearbox does not need to come out or the body off - just disconnect the oil cooler pipers at the oil cooler and pump in the new oil and suck the old oil out - after you have of course replaced the plastic transmission sump with a metal one.

I purchased my first Sport in 2006 and was informed by the UK forums such as D3 and rrsport that most dealers in the UK had been informed to start changing the transmission fluid around 2008/2009 and not go with the sealed for life approach, i am not sure but there may have been a LR instruction on it as well.

I noticed when i had my done that that the gear change smoothed out once again, and less shunt characteristics when changing up.

Don't need the body off for a proper flush - it can be done through the trans cooler lines, then just a standard level check at the end. The pan/filter is easy enough to change with 1/4" tools.
