The drain plugs are not magnetic. The oil plug is 14mm, the trans plug is 20mm.
Thank you so much!

I saw a video of this transmission fluid exchange for the Type R, and the plug did not appear to be magnetic, which is odd unless there is a separate mechanism that Honda chose to filter particulates.

My STi had a magnetic drain plug, which did get gunk after 20-30k miles.

In any case, I will try looking around for a place that makes a magnetic drain plug. A long time ago, I purchased a magnetic oil drain plug from a place called Dimple. They make magnetic drain plugs for other applications like transmissions, so Iā€™ll start looking there.

Thanks again for the quick reply, and if I find a replacement magnetic drain plug, Iā€™ll let yā€™all know in case anyone here is interested.

Yes, those are the correct capacities. And yes, that is the correct Amsoil fluid. I used the Amsoil for about 8k miles and just changed mine out with Redline MTL. The MTL is noticeably thinner. I have only driven the car around the neighborhood so I can't yet to report on the fluid comparison.
Thanks!

Would you say it's worth changing the transmission fluid with just 2k on the car? I think it shifts great but keep reading it can somehow get better?

I am of the opinion that it is always good to change fluids after break-in. I was having some 4th gear lockouts and some gear nibbling when downshifting to 2nd gear. The Amsoil fluid did not completely cure these symptoms but the shift feel did improve. I decided to give Redline MTL a chance since I was doing another oil change anyway. I'll let you know once I get the car out of the garage how the Redline fluid feels. I have also changed my shifter cable bushings and this helped tremendously. However, there is still some slop in the shifter. I am planning to purchase the Hybrid Racing shifter very soon to address this.

If changing your transmission fluid yourself for the first time, if interested, Iā€™ve also posted a step by step DIY with photos:

I took a look at the area this evening to get an idea of what to expect.

Seen here is a picture of the transmission case, with the camera aiming toward the rear of the car. The orange circle is the check-oil plug, and the purple circle is the transmission drain plug for the FK8.

After removing the skid plate, I noticed a lot of small gravel that had been accumulating over time (red circles). The two Phillips screws at the front of the skid plate were very tightly screwed, so I had to get a long screwdriver to get some torque to remove it. Be careful not to try over and over removing the screws with a small head driver , because the top of the screws will strip. Just take your time and use the right tools.

I got 3 quarts of Amsoil, shown here, so Iā€™ll try doing this fluid exchange this month.

I ordered a M20x1.5x14 magnetic drain plug from Dimple, so if it has the same dimensions and thread, then Iā€™ll use it.

Fixed typo - corrected bolt size.

Can you please report your findings on the plug?

I found and bought a replacement magnetic transmission drain plug for the Civic Type R.

The transmission drain plug size is a M20x1.5x14.

Like I mentioned earlier, a company called Dimple from the Carolinas makes very good magnetic drain plugs for various applications. I had one for the longest time on a previous car and was impressed with the longevity of the plug.

Here is a side-by-side (profile) view of the Dimple drain plug on top, and the Honda OEM transmission drain plug on the bottom. I tried my best to illustrate how much space each occupies past the point of contact (with the edge of the box), and found that both plugs span the same length, which is exactly what you want so as not to make contact with anything else in the pan.

As an alternative, Mishimoto also makes a drain plug this size, except it is made of aluminum and has a magnet that protrudes more like a tip. My only concern would be making sure that the tip does not make contact with anything else. If it doesnā€™t make contact, then it would be a suitable replacement plug.

FYI - the magnetic force on the Dimple plug is really strong, so be careful getting it near objects. I would compare the strength of it to the same force that NiteEyez cellphone holders use.

The torque spec for the Dimple is 18 ft-lbs.

Update:

I did the oil and transmission fluid exchange on the Type R today, emptied the residue in the Mishimoto oil catch can, and wanted to share my experience.

First, here are some pictures of the removal of the Type R air box to access the fill-plug for the transmission case:

Note: The air box consists of two parts (upper and lower). I loosened the stainless steel clamp holding the intake hose to the upper part (5.5mm bolt). Then I unclamped the two latches holding the upper part to the lower part (there is a MAF sensor wire that you have to disconnect first, super easy).Next, remove the upper part.

Note2: Remove the air filter. To remove the lower part, you need to first remove the rubberized connector that connects the intake area from that top of the frame to the inlet of the lower part. There are four nubs on the bottom and two at the top. If you have small hands, you can pop them out by reaching inside the connector. Once those are loose, the two nubs at the top slide up and away from the lower part.

The weather-strip at the top, by the frame needs to be removed as well. There are plastic tabs that hold it in place, and the remainder of the connector is held in place too with 2 x 10mm bolts.

Do not yank or start Hulking these parts off the car. Take your time.

Note3: To remove the lower part, there is a 10mm bolt near the battery box and one at the base of the lower part connected to the frame.

There is a rubber grommet holding the bottom of the box to the frame too. BEFORE you start pulling it, there is a plastic tie strap connecting the lower part to some big wire by the battery. Simply unsnap it with a pry tool, and reconnect it when you put everything back together.

Secondly, here is the Dimple magnetic drain plug now installed. It fit perfectly.

The transmission took 2.3 quarts of new fluid. This is the remainder of fluid from the third quart.

Some fluid came out of the check-fill hole and I didnā€™t notice it, so thatā€™s why it looks like I used a teeny-weeny more.

Lastly, I installed a Fumoto oil drain valve after doing the oil exchange.

This oil pan came in very handy, and this oil filter removal tool:

Mishimoto oil catch can had this much PCV residue after 1,674 miles to be exact!!! This was very surprising!

I donā€™t know how many ounces that is in the Starbucks Grande sized cup, but itā€™s definitely more residue than I expected.

Going to order the GM modified synchromesh aka Delco here shortly and was hoping someone can link me to a pump that would fit into the bottle to pump the fluid inside. Amazon preferred
Thank you!

A pump isnā€™t at all necessary. Just use a funnel.

Tip: If you are using jack stands in the front of the car during this process, then fill the gearbox with 2.3 quarts of fluid (specified capacity for the Type R), leave the check-fill plug open, and lower the car before reinstalling the check-fill plug. This will ensure the correct fluid amount remains in the gearbox, and cause any excess to drip-out. If you are using a lift, you may find that 2 quarts will fill the gearbox due to some residual past fluid not completely draining out.

No pump needed if you fill from the top. Just measure 2.2L or 2.3q of fluid. Make sure you get the friction modified fluid.
