Without buying a service manual is there a link, video or step by step of replacing the DCT fluid?

You can explore this forum via the search feature. It's very straightforward.

Get the car up in the air so you can remove the rear shear panel. You'll be able to access both the fill and drain plugs. Make sure you get the fill plug out before you drain. Just to make sure you won't have an issue with getting it filled after draining. Drain the fluid just like you would the oil. I'd let it drain out for a while before refilling. Fill the the trans until the fluid just starts to flow out of the fill hole. Put the fill plug back in finger tight and start the car. Run it in D and R for 30 seconds each for 2 or 3 times. Re-check the fluid level . Add enough to get it to slowly stream from the fill port. Put the fill plug back in and you're all set. Put the shear plate back on. Other than running the car in gear a few times it's essentially like changing your motor oil. Mine took 9 liters. HTH

I did my DCT Fluid and filter change this past summer. Followed the same procedure that Mark9 described above. I also was sure to remove the FILL plug prior to the drain plug, just in case you couldn't get it out....... For the fill procedure, I let gravity do the work for most of it.

I bought this metric threaded hose barb on eBay : along with about 4 feet of 3/8" inside diameter clear tubing and put a funnel on the top side which I fed down through the engine bay and into the DCT. Fed about 8 1/2 liters of DCT fluid through the funnel and tubing until it just started backing up into the tube.

Then removed the fitting and put the fill plug back in and lowered the car and ran it in (drive ) for about 45 seconds, then reverse, then neutral each for 45 seconds, then repeated the process.



After running the car through the gears, I raised the car again on the lift, and checked the fill plug for fluid level. It was down some. For the final fill, I put the threaded hose barb back into the fill port and with a short piece of tubing used this new hand pump ( giant syringe) to pump in another 1/2 Liter of fluid.



I could have just used this hand syringe pump to fill all of the fluid, but letting GRAVITY to the work was MUCH easier.....

When finished up and the shear plate reinstalled, I cleaned up all the fill and drain tools, sealed them up in air tight bags to avoid any future contamination and they are ready to go again. My buddies car is due next, so it will get this process in another month.

Hey Evan, You may want to check out the video below from Paragon it shows how to remove the rear shear plate, the tools and size of all the bolts as well as the torque specs for the DCT filter. The Torque specs for the drain and the bottom side fill plug are 18 ft.lbs. If you're filling from the top, which I don't recommend, the torque for the top fill plug is 9 ft.lbs. Hope this helps.

Note: Since I already have a compressor I used a Vevor fluid transfer pump, got it on Amazon, It holds over 10 quarts of DCT fluid and once connected to the compressor it fills very quickly.

Thank you! I think I have seen that one. I also saw where you really don't need to pull the black panel to lower the shear plate. I wasn't going to fill from the top... I was going to gravity feed to the side fill.

I assume it was a dealer that did these things. You need to ask them, not us.
