So I've been reading up on this and it seems that in ISTA-D there are two sets of adaptations that can be "cleared" on the ZF 6HP26 transmission - clutch wear adaptions and oil wear adaptations.
Obviously, you WOULD want to clear the oil wear adaptations if performing a fluid change but NOT the clutch wear adaptations.
I'm not (yet) sure what transmission adaptation clearing options are available in INPA/DIS/Foxwell etc.... but I am reading that INPA cannot differentiate between the two sets of adaptations and will clear BOTH... not good if that is the case.
