Any reason why the electric fluid pump as used in boats wouldn't work? Taking a look online seems like it would work perfectly. Snake the hose in, turn the pump on, suck out fluid then use a regular gear oil hand pump to pump a litre worth of new stuff in...
Any oil recommendations for the tiptronic diff? I know it's supposed to be 75W90 but can't find any info on the correct GL rating as in GL4 or GL5 or brand recommendations...Pelican sells "Titan" diff oil but I would rather use a Redline or Swepco product if available as I'm sure many of you reading this would too.
