Some official aisin marketing stuff below for what its worthDo you have a link or some pdf from ZF?
Because that’s my issue, I hear 60k miles, 80k, 30k it’s all over the map and it’s all hearsay.
Same on aisin, ok, fluid has to be changed, but which fluid type, which method, which interval, and where is an official source for it?
Personally I think 20k kms listed by Aisin is excessive and that around 60k to 80k kms is fine if doing a full flush out of old fluid and full charge of new fluid. If doing just a drain a refill where you replace about 1/3 to 1/2 of the fluid in the transmission then do it every 30k to 40k kms.
