Took my truck to Florida from New Jersey last week and towed a double PWC trailer. Only got 11.6 MPG during the trip. Also has some problems with hesitation in the enjing and bucking when the transmission shifted into high gear, even after dropping the trailer. Took to a Ford dealership and the had to replace the coil that had a hole and fouled the plugs and engine. The engine was all carboned up and the plugs needed to be replaced. The transmission fluid was thisk and black. They flushed the tranny. Now everything seems to be running good. No hesitation and no bucking. When I get back to Florida to run the truck some more, I will see what the MPG is. I sure hope it is much better that the 11.6.

 

Is there a question in there?

 

No

For information only, incase anyone else finds they have a similar problem with fuel mileage, etc.

Sorry for the confusion

 

when towing a trailor it is a good idea to cancel the overdrive. This prevents the torque converter clutch from engaging. The heat created by the converter clutch under the heavy load of the trailer is what burns up the fluid and can cause other catastrophic transmission problems.

 

I did have the OD turned off the entire trip. I learned this the hard way many years ago, when I was the Director of Public Works here in New Jersey. Several of our drivers would plow snow with the OD on and it costs us several transmissions. I did by this truck used in December, so I don't know how the previous owner drove it.
