My 2007 Ridgeline with 158,000 miles has developed a shifting problem. When I move the shift lever from Park to Drive the lever stops at neutral and will not continue into the Drive position, this renders my vehicle undriveable. I can go back up to Reverse or back to the Park position but when I attemp to bring the lever back to Drive it will not move beyond neutral. I have to continually move the lever up and down trying to feel my way into drive and after several minutes of jockeying the lever it will unexplainably shift into drive. It will be ok for a day or so then the problem reoccurs. Honda tells me being that as it is intermittent they cannot diagnose the problem until in the problem is repeatable. I have had the problem several times and twice called for a tow truck only to have the problem disappear after after playing with the lever for several minutes. The service department says this problem is a new one for them. Any suggestions.
