Made a custom bracket to mount it instead of the plastic ties.
I needed some additional tubing and some barb-to-flare fittings as well to complete the install.
Here are some notes for anyone else looking to install the Hayden 678 on a 2nd generation MDX (probably also applies to Honda Pilot but not sure):
-When I installed the provided hose on the cooler hose barbs, the first one slid on effortlessly but the second was a battle, even with silicone lubricant. I fought it for about 30 minutes and still couldn't get it to seat all the way down. I ended up cutting about 3" from the hose and then it slid on perfectly. I examined the interior of the cut section and it didn't have any flaws. I can't understand why I had such trouble.
-As in the video I mentioned, you can do this installation without removing the front bumper/fascia by bolting the cooler it to the existing transmission oil cooler bracket, however, the flange on the Hayden cooler is not wide enough. You will need to fabricate some metal tabs to add width to the flange.
-Also as in the video, I secured the right side using one of the provided plastic "zip tie" fasteners.
-You have to remove the plastic skid plate/cover from just behind the bottom of the front bumper to access the transmission lines. I also had to jack the front of the car up and put it on jackstands to get some clearance to maneuver my arms.
-There is a flat, roughly triangular metal bracket right below the transmission lines that is held in with three 17mm bolts. I removed the front two and loosened the back one and pivoted the bracket out of the way. Unless you have incredibly small hands and/or a lift, I don't see how you can do this job without moving that bracket but in the video he somehow does. There is also a small hose in the way that I disconnected 2 white clips from the car frame so I can move it around a bit.
-I was concerned that there wouldn't be enough hose but there was about 9" more than you actually need for the MDX. Just be very sure where you cut so you don't come up short on one end. I used a pair of anvil pruning shears and they cut it beautifully.
-On my 2011 (and in the video) the return line was the line that has a canister-style filter on it about 6" from the metal barb. Confirm though by running your engine, shifting through the gears, then shut the car off and feel the two hoses. The cooler hose is the one you will tie into.
-Slipping off the hoses results in transmission fluid loss. I probably spilled about 1/8 quart doing this. If you have another person with you it might help but the area to work in is so tight I can't imagine it would help much. I slipped the new hose onto the newly exposed metal barb and then connected the old hose to the other length of new hose using the flared aluminum pipe Hayden provides and 2 hose clamps. Make sure you have the hose clamps on the hoses before you do the switch. You will need an extra hose clamp as well with this installation method.
-When I turned on the car to check for leaks, everything was fine except I was getting a few very tiny bubbles at one of the connections on the flared aluminum pipe. I think the hoses on the Acura are about 1/16" wider than the 11/32" hose Hayden provides. I tightened the clamp down further and the bubbles disappeared.
-Remember that you MUST replace not only the transmission fluid you spilled but also you must add a little bit more as there is now more capacity due to the new cooler and hoses. I added about 200 millilitres to start and will check after driving for 15 minutes and top up as necessary. Adding transmission fluid to the MDX is a minor hassle - you either need to have a funnel with a long flexible tube to fill via the dipstick or you need to open the fill port on the transmission which requires a long socket extension and some brute strength.
I hope this helps someone!
I bought a 3 ft. stick of 1/8”x1” steel flat bar from Lowe’s and cut it in half to make my brackets. They have a slight S bend in them as the video suggest doing so that the cooler sets a bit further back closer to the AC condenser.
Overall it wasn’t too bad of an install. Took about 3-4 hours including cleaning up my tools and shop. I can comment on the effectiveness because I don’t have a temp gauge installed at this time. (Possibly a future addition)

Previous to install while pulling my travel trailer up a moderate grade, the temp gauge would peg just below the high mark.
After the install, it never went past the half way point on a 95 degree day on a 7 percent grade.
Took about a half hour to install, definitely a must have if you own a Titan.
