I have an '07 Ridgeline with 170,000 miles. When I pull the gear shift lever into drive sometimes the trouble light comes on indicating that the gear selector is not showing the right gear. This doesn't happen all the time. I think I may have a loose wire but don't want to spend $250.00 at the dealership to have it replaced. There is no problem with gear shift going into the correct gear. Does anybody know how to fix this ?
