Hey guys so last night I was planning on changing both my engine and transmission oil, simple enough.
Oil change piece of cake as usual but when I went to crack the transmission fill bolt ( Thankfully I did this before draining my tranny), I noticed that where my fill bolt is on top of the transmission, there is a black L fitting with tubes attached right on top of the bolt?.
Super confused because I have watched countless videos on doing a transmission oil change and none have this.
What is this and how do I get access to the fill bolt ? Ill attach pics to show what I was expecting to see and what mine looks like for reference.

My bolt under the '602' fitting

 

My '00 TL had the same thing, don't recall the purpose, but think it had to do with the myriad of transmission issues in that generation.
Just have to remove the bolt on the '602' bracket & pull the hose out of the fill bolt.

 

I fill mine through the dipstick tube--it's more fun that way!

 

It's called an Oil jet. It was a "fix" from Acura to slow down the failure rate of 5-speed transmissions .
