Manual Transmission Check Bolt

Manual Transmission Check Bolt
My car just hit 60k and I decided it was time to change out the MTF and transfer case fluid. The transfer case fluid went by without any problems, the MTF, not so much because it took me an hour to find the check bolt.
So my fellow 6MT drivers, I decided to post pictures of the check bolt to help you out if you're going to be changing your MTF soon!
I have a few tips, some are obvious, but I always say the more information the better
-Make sure you can open your fill bolt before draining your fluid, it would suck to drain your fluid only to find out you can't refill it.
-The fill bolt is pretty hard to take off, even with a breaker bar, so you might wanna have a beaker bar to take the fill bolt off.
-The directions for changing the MTF states you have to remove the splash guard... I found this to be true, otherwise you're not getting to the check bolt and you'll potentially get MTF all over your splash guard when you're draining it. I know that it sucks to have to remove 4 bolts and like 10+ of those fucking clips that never seem to want to come off, but yes, the splash guard needs to be removed.
-Make sure your car is level when you remove your check bolt to ensure an accurate reading.
If you're curious about the type of fluid I used, for my transfer case I used Mobil 1 70w90 gear oil and for the MTF I used ACDelco Synchromesh p/n 10-4014.
Anyway, that's how my morning went, enjoy your weekend everyone!

I unfortunately/fortunately have about a one mile
commute. Ive only used Acura for the few services ive needed so I should have Honda Mtf. Probably should look into changing it soon. Thanx for the help

With that being said, my gears shifts are noticeably smoother now. More recently I would sometime not be able to shift into 1st gear and I would have to shift into 2nd then 1st. I am able to shift into 1st just fine now. I probably shouldn't have waited so long to change my fluid but I was kind of waiting for the MID to tell me when to change it (it still hasn't btw). At this point I think I'm just going to do a drain and fill yearly.

Wish I saw this a month ago
that bolt was relatively hard to find! Wish I saw this a month ago when I did it.
i put the synchromesh in mine, but since I bought the car used at 130k miles, i don’t know if it had been changed before. Shifts much smoother now

i cant remember exactly how much came out of the overfill bolt... seems like I started with 2.2, but when no fluid came out of the overfill bolt, I added a little more 2 or 3 times before it finally started coming out...
