Lately, on two occasions, my transmission seemed to have slipped into neutral while in D5. I was giving it some throttle, and the engine would just rev up. I've also noticed some less than smooth shifting, and slow shifting.
I will be taking it in. Fortunately, I have a letter from Honda Canada saying that the warranty on the transmission has been extended to 93 months/175,000km. Maybe I'll be getting a new one.
