Armed with the answers I got here, I did the drain-and-fill last night. Seemed to go without a hitch. This was my first ATF change so I don't have a lot to add to the body of knowledge on this topic. However, I have added pics because everyone seems to love pics.
- Picked up the drain plug washer at my Honda dealer for the low, low price of $3.50. Since I didn't know exactly what it was, I didn't try to get a cheaper replacement. But Seriously Honda - $3.50? I kept the original and will know better next time.
- Parked the car when I got home, put it up on jacks and emptied the pan. The fluid was very warm -- luckily not quite hot enough to scald me. I did a poor job of containing spillage in my driveway. Oh well, live and learn.
- I originally thought my fluid was pretty clean but that is because I had never seen new DW-1. New fluid is much lighter. I have attached a pic of the old and new fluids. Now I am very glad I changed it.
- As I was warned, drain plug magnet end was coated in metal shavings. Pic attached. Wiped it off and coated the threads in new oil.
- My long trumpet shaped funnel wasn't even long enough to reach the dipstick hole. Will have to add some tubing to the end for next time.
- I panicked when I started the car up after the change -- the car wouldn't go into reverse! Holy cr*p -- I broke my transmission! Turns out I had forgotten to remove the chocks from under my rear wheels.
Seems to drive fine now. Thanks to everyone who gave me answers and courage to do this myself. Fellow newbies, if I can do this -- anyone can!
