This is the FIRST time I have seen the Honda transmission cooler being listed for BOTH the 6 speed and the 9 speed transmission. Last time I had looked during thespring there were two separate part numbers, one for the 6 speed and one for the 9 speed. The 9 speed one was about $300.00 or so and the 6 speed one about half that price.having just done this with the OEM kit. the hose that is marked "do not reuse" is one that was attached to your transmission to the filter. you remove this hose and attach the ones from the kit. Make sure you have enough clearance or your will be doing this for a while. I had to cut the old hose after removing the clamps from it.
Not sure where you are going to get your OEM kit.. but I got mine here 2016-2020 Honda PILOT 5-DOOR ATF Cooler Kit 06255-RLX-306 | Honda Superstore Parts @ $140 plus shipping was $156.68
There was some discussion also by others looking for the 9 speed one at the time saying some of the dealers were showing it was discontinued. I had decided to wait and looks like I may have made the correct decision if this new part number can in fact be used on the 9 speed for half the price of the old part numbered one.
Anyone install it on the 9 speed yet?
