Mazda sell it as seal for life atf. Never change atf if follow sc. My old waja automatic only doing atf change every 40k km by outside workshop, it still working great to 300k km, only lost it to theft, my buddies Toyota Corolla Seg, 550k km also regular atf change only. But my dad old w210 had this jerkiness gear for gear 4-5 and resolved after perform atf flushing, until let go of it for w211 long time ago

Suggest ts to send workshop that can do ATF flushing instead, using those machines. Hopefully this over run atf to 260k km dont do hardware damaged yet.

Actually AT flushing just make it worse, as the debris might dislodge and stuck in important areas like bodyvalve if force flush. Previously one of my favorite mechanic also got 1 AT flush machine, after few car use and encounter the weakness already ditch the machine at the side.
Like some member feedback, the safetest way maybe change 50% of AT oil first, shorten the oil change intervals until 100%. I believe that will be the lowest risk.
