I have a friend and fellow DTR member that called from the road. He is driving up from Florida to Pa and has a problem with his 96 Dodge 3500 Auto CTD. Everytime he hits a bump his truck goes out of Overdrive and then he has to rev it back up to get it into OD. Also his cruise control went out at the same time. Any help would be great and I'll call him and let him know. Pete
