When is the last time you had the fluid changed? At any time did you notice the "D" light flashing? There may be trouble codes stored in the trans control module , might want to have it scanned at a shop with a scanner that can communicate with it.(generic code readers won't do it) Use only Honda ATF. Drain & refill only -NO FLUSH! If fluid is really old & burned , Do 1 drain & fill(about 2&1/2 quarts) , drive it for maybe 20 miles & drain & fill again. -
