I've 03 EX with 7500 miles on it (just 4 months old). I've observed since last 1 month that when I'm on highway around 70mph at that time my RPM remains at 2K. I have to push it bit hard to move it upwards when I want to move from 70 to 80 speed but once again it drops back to 2 to 2.5K although I'm at 80 mph. Is this okay or I need to get this thing checked with dealer. I hope I'm not having any tranny issues. My vehicle vin is outside tranny issue, but still not sure.
