I think he's referring to when his car goes into the final drive gear. (highest gear possible/normally during highway traveling) My guess is that there is a problem with the tranny. But first check the trans fluid. Or even have it changed just to be sure. If that doesn't work take it to honda AND MAKE SURE you go on a test drive with them to point out the problem. A lot of times a service tech will take the car and bring it back saying nothing is wrong
