I just went into the shop with the same problem with my 2002 MDX at 40k miles. Between 25-30 mph it would fail to shift on occasion and rev a good bit before catching up. Dealer ordered new/reman tranny and will replace this week. The funny thing is that when I took it in for the problem 2 weeks ago, he said something about no codes showing up and it didn't show up on a test drive. New tune this week.tom54tay said:My 2002 MDX (40k miles) has just gone into the dealership for transmission problem that has been brewing for several weeks now.
