RepairPal Certified shops can diagnose and repair your 2010 Honda Pilot. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
Honda's do like to eat trans parts, and they don't hold a lot of fluid in them either. You'll need to have a diagnoses done on that one. Remember your pilot requires a lot of sensor info, and tolerances are not to be messed with.
