Any transmission experience here? Was getting an "A3" warning on 2009 Honda Pilot with 147K miles, which as far as I can tell is the change transmission fluid warning. It was past time anyway, so changed it. The plug head is magnetic, and looked like it had heavy lubricant on it, but I'm worried it was debris from cumulative excessive wear in the transmission. First image show the sludge on the drain plug. First paper towel shows sludge wiped onto towel. Second paper towel shows general hue of fluid. Third paper towel shows what was at bottom of drain pan, which seemed pretty clear, which gives me hope that it's okay. Does Honda factory put lubricant inside the transmission before adding fluid?

No pics. But that isn't lube. It's debris.

Not the end if the world.

It takes roughly 7 drain and fills to hit a purity of over 99% new fluid.

You can only drain about 40% out each time if I remember right.

Change 3 or 4 times then once every 30k. If behind a V6 then it's a time bomb.

How often are you changing your transmission fluid? I believe you are supposed to change it every oil change, or every other oil change (you may want to double check your service manual). If you haven't changed your fluid in a while, that debris appears to be normal.

Debris on plug and color of trans fluid looks normal for 147K miles but the fluid needs replacing. Fine uniform metallic particles like a paste on the drain plug is good/ok and chunks/pieces of metal is bad and expensive

That's why you are better off with a transmission flush. It completely flushes out ALL the old fluid and replaces it with ALL new fluid. Do it every 50K miles.
Find a shop that offers the flush using the BG machine and BG products. Use the BG Find a Shop for service near your location.

When was it last changed prior to this one? If greater than 50K, my auto tech recommends a double drain and fill for Honda’s. Drain and replace the fluid, drive it for 10 to 15 minutes, until transmission has come up to operating temperature, return home and then drain and refill a second time while vehicle is still warm. Thereafter, a single drain and fill at 50K intervals.

Use only Honda AT fluid from the dealership specified for your vehicle. The double drain and fill helps to better clean the non-replaceable internal transmission filter for Honda’s that have had extended intervals between transmission service.

Never flush a honda transmission.

Hell, never power flush any transmission.

There are Honda dealerships all across Louisiana and the south performing transmission flushes daily.

You keep draining and adding new trans fluid to the old burnt fluid still in the transmission that regular changes can't remove. You're just contaminating the new fluid by adding it back in with the old remaining fluid. One just has to use the correct fluid in the Honda's.

This is what I saw, and my gut tells me you're answer is the right one. Thanks. I should probably change it again for longevity, but I'm not going to "flush" or anything - heck this car is lucky I drained it at all. Just trying to get a few thousand more miles out of the old family SUV that has been abused with years of wear.
