Per ZF with regards to all passenger AT severe service is 8 yrs or 80k-120k KM where vehicle was operating in " frequent hwy driving in top speed range", "offensive,sporty driving style","frequent trailer operation".
The conversion to miles 48k to 72k.
Something to keep in mind is that these new units are holding up very well under normal maintenance. You just don't hear about failures from used car owners.
