Thanks for the advice. But what about the procedure since we have no access to the reservoir (to remove mix of old and new fluid) while the airbox is off? Is it a constant shuffle of the airbox?
1. Remove airbox
2. Use baster to remove fluid from reservoir
3. Add new fluid to reservoir
4. Install airbox
5. Start engine, turn steering lock-to-lock a few times, wait a few minutes
6. Kill engine, remove airbox
7. Repeat #2 through #5 until fluid in reservoir looks brand new

I'd like to not throw any codes if I can avoid it.
