Hi - I have learned a lot from you folks and I hope someone can help me understand what my truck is doing. My truck does not coast. It always seems like the transmission is braking. Not a lot but when I let off the gas there is a noticeabIe drag. I have had the truck a year and have put about 15K miles on it for a total of 42K. I have not had it in the shop for this. Also, if I am driving and I put the tranny in neutral the RPMs do not drop to idle, they stay up where the engine was running in gear. I drive a Ford 1 ton dually at work and when I left off the gas in that thing thee engine goes into idle and you can feel the truck coast easily. I know this has to be affecting my mileage. I have to give it gas go down fairly steep hills. I get about 14 mpg now. Any ideas or comments will be appreciated.
