Bolt that has blue on it, looks like it has a crush washer that is seeping. On transmission. Why is this bolt blue and why does it have a crush washer on it?

Reason: Typo
Yeah I am sure its transmission fluid that is gunked up. Stupid for me to ask "what is seeping" But I am more curious about the bolt with the washer. Just didn't know what to title the thread. I just drained my transmission fluid for the first time and noticed that bolt with a blue marking and a crush washer...Surprised no one knows what that bolt is for. Anyone with a service manual that knows?
Nah, there is a crush washer on the ATF drain bolt (at least on '04 / '05 ATs). They probably didn't replace it with a new one, although I've reused my oil drain plug crush washer many times without an issue. Or maybe the bolt just isn't tightened to spec?
FYI, torque spec is fairly significant, at 36 ft-lbs (again, reading the 04/05 SM).
I'd put a torque wrench on it and see if it's tightened to spec. If not, tighten it to spec and then clean off the area and see what happens...
If that is not applicable or doesn't work, then now is the perfect time to get a 3 x 3 drain and fill done while you replace the crush washer and maybe the bolt....

to me, it looks like some one replaced that blue bolt. and OP says there's a crush washer on it...which shouldnt be there...as that is a bolt to the transmission case....not a drain bolt
also, I know this is a new to you car, 4door...
Sorry that you're going through all these problems ( i remember reading you had a few more problems with it?)

Nah not really any other problems. Car had the original air filter in it. Which was like black. I changed that out. I also put a new AGM battery in it since the battery in it was close to 5 years old and was only at like 12.2-12.3 volts.
I did the cabin filter and broke a couple plastic clips. Luckily it went back together fine and doesn't rattle or anything so not worried about the clips. And I recently just changed the transmission fluid for the first time. That is when I noticed that bolt with blue on it seeping. Yeah it has nothing to do with the drain bolt which was dry as a whistle. Going to carb clean that nasty area tomorrow, inspect it more and perhaps tighten it down some. I have to put the splash shield on anyhow since I left it off. Tranny fluid was easy but the drain bolt and fill bolt were torqued to like 200 ft lbs! (Never been removed I assumed)
I already ordered a ton of parts for the timing belt install. It has 77k on it, but it is almost a 9 year old car so the timing belt is due. Having that done with a valve adjustment.

Interesting... Judging by the color of the bolt and other comments, it's highly likely that it was replaced at some point. The why it was replaced is the answer that we need. My guess is that this area was leaking prior to replacement, so some shop replaced the bolt and added a crush washer to try an alleviate the issue. Just a guess though.
I'm not super versed on this car and what the bolt is for, but it's definitely on the transmission and that certainly looks like dirty tranny fluid leaking out.
My only guess at a fix is to replace that bolt with an OEM one. Finding that specific bolt could be the hard part though.
I would keep an eye out underneath the spot where you park the car and see if it's still leaking and if so, how much.
Which is labeled as a sealing bolt. The previous owner may have tried to undo the bolt to drain the fluid in the torque converter as part of the drain and fill. There also happens to have a gasket #17) My reasoning for this theory is the head of the bolt looks partially sheared off where a socket may have slipped.

If I was 4drturbo, I would start by buying the bolt and gasket (crush washer) and replacing. Either #14 or #13, both are labeled as sealing bolt, but the bolt pictured does look like a 10mm (#13), if not bigger. Damn, good eye thoiboi. Maybe I'll send you a picture of this particular clip I am looking for.
Bolt does look sheared, I'd be careful trying to remove it and put the biggest breaker you can under the car in case it's torqued in there real good. My guess is that hack who put it in over torqued it to try and seal the leak.

BY all means

My assumption as well after looking at better pictures.

So some one else making a thread state the drain bolt is on the opposite Azine DIY on a 07-08 TL. so this must be it.
The blue mark is a factory crayon mark to show that the part met all inspections before it was installed and verified by a few folks on the assembly line. You'll fine odd marks and colors all over the car from the factory to ensure all steps were taken and verified.
The bolt looks like it was loosened in the past. A new crush washer and you'll be fine!

Thank you very much for that diagram, It must be #13. I will keep an eye on it since it is all cleaned up.
