Your article mention that…
Your article mention that Subaru techs say the "lifetime" transmission fluid does not last a lifetime. Is it just me, or is this the Subaru techs acknowledging that the transmission fluid is in fact being referred to as "lifetime" when it does not actually last a lifetime?
Also, one of the tech comments said to change it every 60,000 mi and then you say change it every 30,000 mi.
Maybe I am not understanding correctly, but when reading the article it seemed that there were a lot of inconsistencies (lifetime, 60K, 30K).
What does the Subaru maintenance manual say as pertaining to transmission fluid change for the specific year of Subaru that the customer owned? It seems this would be the most straightforward way to answer the customer's concern.
