I don't know if you'd count it as an oil change, but I did a drain/refill of the ATF in my girlfriend's '01 Civic LX (55,800 miles) yesterday. Used 2.8 quarts of Amsoil Signature Series Universal ATF. And I learned a valuable lesson: do NOT take out the transmission dipstick before pulling the plug. The fluid came out with so much force that it sprayed all over part of the frame/suspension under the car, and down the driveway. That was quite a mess... and it made refilling the car difficult as I couldn't fully measure how much fluid came out like I usually do. Next time, the dipstick stays in... The last time I changed it, I left the dipstick in and had no problems at all.
