What preferred transmission oil is recommended to flush out savings in the transmission
What oil is recommened
i would use type F...but what do I know ...i closed my transmission shop years ago.......TYPE F
I would flush it with the same fluid you would use to operate the transmission. That would be DexIII/Mercon as your transmission came with a factory fill of DexIII.
I agree with Tom, use the same fluid that you normally use. Don't use anything else.
