I have a 2003 Accord 2 dr EX Coupe with the V-6 engine in it and the 105,000 miles in mint condition and serviced regularly and the other day while driving down the road at about 60 mph the car jerked hard and down shifted out of overdrive and then again in about another 20 yards and now with no shift out of 1st gear or go into Reverse at all! Checked the Transmission fluid and it seems to be fine! Any help as to what this might be?

 

welcome to the forum: your 03 accord has a trans recall 04v176000 2004-apr15 call your honda dealer and ask them what part of the transmission failure will they cover.
