2nd Gen Non-Engine/Transmission Looking for a good repair source dealer or other wise

[REllerman]

While pulling my fifthwheel from Florida to Michigan, I pickup a rattle that sounds like a metal plate rattling when I'm going from a stop through first, second , and third gear above 2000 rpm. It doesn't do it all the time only once in a while. Before I head back south I want to get it checked out. Can any budy recommend a good place or dealer in the Detroit area? WE visiting in the Hartland area. I hate to just pick a dealer out of the phone book. Any help or info that you guys can give will be greatly appreciated.
