Normal feature on the Titan. It is a type of engine braking, saves wear on the brakes. Nothing to worry about. 
No, no! Never do that. Not a good thing for the drivetrain, and decreases safety, as you've lost power if you need it in an instant. Just not an officially recommended practice anywhere. Many will do it, but that's not enough reason.titanmike said:put it in neutral
Put it in '4' instead of 'D' and it doesn't do it... It kind of bugs me too... I've never been a big fan of things trying to think for me.spoonman said:yep, as everyone else said, its normal although i wish there was a way to turn it off. For some reason my truck doesnt coast for crap anymore even on flat spots. As soon as i take my foot off the gas it decelerates because of the feature.
I have read on here that in neutral, the transmission fluid does not circulate. So if you're going down a long hill in N, your tranny is not lubricating itself....TitanBlue said:No, no!

Stupidity? I can't argue with that, however, one of the biggest reasons that manual trannies are being phased out is because of the HP that today's engines produce. The torque converters on the manual trannies can't handle it and as R&D was being focused on automatic tranny technology, this little issue kind of fell onto the "not so important to figure out how to fix" list.Titanic9 said:My '07 does the same thing. You don't have to be on a big hill at all - it will do it even on a slight grade. I don't really like it because normally if I wanted that behavior I'd just downshift to 4th manually. I don't like the truck doing it for me.
This coming from a person who believes that all automatic transmissions suck. A manual transmission is a beautiful thing - simple, easy, and it never does something wrong or unexpected. But since people are stupid and can't drive in North America it is getting harder to find vehicles with them.
BB, I think you are confused. :wierd: Automatic transmissions have torque converters; manual transmissions have clutches. Also, manual transmissions can handle more torque and horsepower than automatics. Plus they get better mileage.Blackbeauty said:Stupidity?
