happened when pulling out of parking, truck shifting was rough (almost a clunk). Then it would not got past 3rd gear. Check engine light came on. I checked code P0733 (Gear 3 incorrect). Engine of course is at high rpm during 45 mph drive home. Called dealer. They said at least 2 weeks to get in for transmission problems. I told them the vehicle was no longer safe to drive (this has happened before), They said call roadside assistance. Ready to call the district rep.
