All the advice says
"Do NOT have a Power flush performed"
"Do NOT use flusing fluids"
"Do use the Correct spec ATF"




the "gibbons" method where you take 3l (ISH) out of the transmission sump + refill with The exact amount you took out , check levels, drive (varies between a 100/200/400 you choose) then do it again, for a total of 3 dumps/refills
is the General consensus on these autoboxes.



Most of the Other manufactures who use the AW55 box we have Do have a ATF change schedule.


best to get it done Before any issues start showing up as by the time they do it Maybe to late
i must admit i am struggling in my head on the atf change.

my 2.4 petrol auto transmission is just under 230k miles. never changed the atf - just blindly did not think about it given the operating manual.

in the last few months the transmission begun rumbling at times, whining at others - but still goes through gears without trouble.

i got in touch with the local specialist who does transmissions only - nothing else. they basically said - sit tight; no issues with gear changes then do not touch it, otherwise you might cause more issues that you are trying to solve.

granted they are not volvo specialists, but they ARE transmission gurus.

any practical input, especially if anyone has been without atf change for as long or longer?
