would take 2 litres or so..there are 1 large 14mm or 17mm bolts, that are a filler (top one) and a drain plug (bottom one)..drain the oil..put the drian plug back in..undo the top plug and fitt it till it overflows out..once it stops leaking out your all set..put the plug back in and away you go..if you run out of the stuff your using just top it up with auto fluid..i hardly ever use manual gear oils anymore..auto stuff is soo much slicker! (i usually use a 80% auto 20% manual gear oil, in my cars)
