Transmission Whine Bob G 9-17-02  
I just returned from a 5500 mile trip with my recently purchased 1996 32' Sunsport with a 460 Ford Superduty chassis. Throughout the trip when ever the RV is coasting (no acceleration or deaceleration), with no load on the transmission a noticable whine can be heard at just about any rpm or gear. This whine will dissapear immediately when the throttle is released slightly or increased slightly when the gears are no longer "floating".

Since this is the first Ford RV I have owned I want to know if this is normal with this transmission. It only has 30,000 miles on it and otherwise performs normaly with the temperature staying at about 180-190 on a flat highway at 65 mph.
Re: Transmission Whine Joe 9-17-02  
You probably have a differential whine. You would need to check (or have a shop check) the backlash. Drive your motorhome for a few miles and see if your differential lube has a glitter to it.
Re: Transmission Whine Tom 9-23-02  
I agree with Joe. That sounds more like the driveline behind the transmission. I agree your ring/pinion gear backlash should be checked out.

good luck.
