I have a problem with my 2018 odyssey. The transmission seems sluggish and makes noises. It seems to take forever to pick up in low gears and when I put it in reverse I hear a click. Honda America says they have no recalls but someone I know says they have a SB service bulletin pertaining to transmission issues. I am doing my transmission drain and fill up at Bridgestone because Honda is charging 200 more. I have always been a Honda Guy but I am becoming skeptical about how they made this 2018 Honda Odyssey it has given me nothing but problems from the sliding door to the other day all Warning signs coming on. The transmission issue has been on going and Honda has claimed this is how the 9 speed transmission is supposed to function.I have a steep drive way and noticed that even when I manually shift to 1st gear, it seems to downshift again to climb up at slow speed (like 1-2 mph). Maybe you are feeling the same thing? I wish the display would also indicate the gear its in instead of just D.
