I guess I need to find out myself and probably post an update again after 6 months or so.
5 additional years on top of my 6 year old SUV is acceptable because that is the normal life of a tranny even being maintained with OEM fluid. Other tranny such as ZF is even worse because their repair manual implies that significant wear could occur after 80k km.
From my research, JWS3309 is simply Toyota T-IV or Aisin AFW. The AFW+ is the higher grade version. Similar to those Dexron ranges.
Out of curiosity, how many of you actually using other than volvo genuine fluid?
