Just had mine done yesterday,this is how it went:
1:Get new gaskets,new filter(your choice,I did),7 ltrs of Dexron 3
2:Take off front sump(engine off) put a bowl underneath to catch spill.
3:Take bolts out of large rear sump,apart from 2 front ones, then back of sump will lower as you unloosen 2 front bolts,but dont take them right out just yet,give sump a bit of a shake to spill into bowl beneath,when most is out take 2 front bolts out and its off,giving access to the filter.
4:Clean magnet in bottom of large sump,replace filter and reassemble sumps,we used a pressurised garden sprayer the type with a hose to get the dexron 3 in until it started coming out,then we lowered car and just went back and forth for abought 5 mins then jacked it back up onto axle stands,with the engine running loosened the filler and topped it up again until it started coming out again,then went for a quick run(couple of miles).Back on to the stands and top up again as you did previously.

I got one of the member to do mine as I didn't feel confident enough to do it myself but watched him and learnt,so I will be doing mine myself in future,piece of p*ss

Good luck its easy or it seemed it watching someone else do it
