I have one of those and they are excellent for this kind of job. Transmissions, differentials, transfer cases etc. Also, it's big enough to get a gloved hand inside of it, so I can wipe it out when switching from trans fluid to gear oil.
Good to know. The question I had about it from just looking at it, trying to figure out a way to adapt it for @johnloov is, what the heck is this fitting on the end in the stock photo?

I think for the tiny check hole in our cars, finding the right combination of fittings (plus maybe a quick disconnect) to adapt that back to the flexible hose for use with a M6 barb fitting like the one I posted would be perfect and mess-free. But I can't identify what they have going on there.

I believe that this is a friction-ring fitting in order to hold the filler tube in place. There's probably a way to adapt smaller tubing onto the end of the filler tube in order to fit it into the opening on the top of the transmission.

Do you know what the threads are if you remove that? (No chance they're engraved on the fittings themselves?)

Yes, perfect.

So @johnloov and anyone else looking to set this up to fill the transmission, you would need:
And, optionally to give you the ability to fit multiple attachments to the end (this would replace the need for the swivel fitting also):
I think that would work pretty good if you were dedicated to changing the trans fluid often, such as after track days.

Will a dealer give me shit about having an aftermarket intake (PRL) when they need to do the transmission fluid change seeing how the airbox needs to be removed? Did I read that right?

If you have aftermarket parts on the engine, why does the dealer "need" to do any fluid servicing at all? Do it yourself or have a trusted shop do it and keep the receipts.

I don't want to do it myself.

I supposed a local shop can do it.

This is a loaded question - some dealers "care", some dont. An after market intake doesnt void your warranty or anything and tbh they may not even remove your airbox with the tools they have available.

I guess what exactly are you worried about?

absolutely true with the magnusson moss act. But it doesn't mean they can't give you a hard time or outright refuse and see what you do about it.

A lot of them are counting on the fact that you won't escalate it any further than a complaint to Acura. I know my rights but there's no way I am actually litigating this for something other than the engine absolutely blowing up.

If you mod the car, you just have to be prepared for the potential of having issues with warranty claims - that's it.

Prepare by keeping the stock parts on the shelf instead of selling them.

Amazing thread, I was going to take the car for service at 10k miles, but this gives me full confidence I can do myself. Thank you very much OP. I have never done but I do have the tools, patience, and time needed.

Make sure you have an appropriate torque wrench for the M6 check bolt or this might happen to you.

I'm guessing most people don't own a torque wrench that can accurately do 9 ft-lb.

I purchased this 500cc syringe in the hope that I could use it to fill the fluid through the check plug

https://www.amazon.com/dp/B0DPW9D75D

so far, I've only used it to suck all the coolant out of the OEM expansion tank prior to installing the PRL expansion tank. the syringe worked as advertised.

No matter how gentle I believed I was, I snapped quite a few bolts in my life... the bolt extractor kit became one of my frequently used tools :-(

I then purchased these two torque wrenches:

https://www.amazon.com/dp/B07M68FY3X
https://www.amazon.com/dp/B07M68G49R

I look up torque specs, set the wrench to about 10% less than spec, then adjust the wrench to spec and gently tighten again.

I have not snapped a bolt since
