Are you having blue fluid?
Only reason I ask is I have read from multiple sources that it's discontinued by ZF, Shell and VW/Audi. Lifeguard 8 is exactly the same as 6+ but dyed green instead of blue.
Also of interest, when Jaguars ZF 6HP have the hoot sound they remove a litre of ATF and add a litre of ZF Special Fluid 1.
