Just wanted to throw this out.

I live in Western PA, lots of hills (or some may say mountains). When I am coasting down a hill with my foot off of the accelerator my truck (07 CC) will down shift on it's own. If I either put my foot back on the gas (which defeats the point of coasting) or move the shifter to 4th then back to drive it will then coast. Is this normal and does anyone else experience this?

Normal feature on the Titan. It is a type of engine braking, saves wear on the brakes. Nothing to worry about. :)

Kind of disconcerting the first time it does it though! :lol: I'd had mine more than a year before I became aware of that feature.

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.

Thanks for the reassurance, sure does stink, especially where I live. Really cuts done on the MPG's. I normally down shift manually when I am coming to a stop anyway. Thanks again for the info.

Great site.:rockon

If it does, just a little blip on the throttle will disengage it.

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.

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.

A lot of the new superduty diesels are coming out with this feature. It's a lot more noticable on those trucks and is meant to slow down the truck and save the brakes. I test drove the Duramax and Dodge in the last few weeks and both had this. The Dodge was so annoying that you can't take your foot off the gas without it just about throwing you through the window by it downshifting. Of course, it can be turned off by turning off the 'tow mode'

The strange thing on the Titan is that it's somewhat unpredictable and erratic. I've messed with mine and at times I can't get it to work... Usually, I'm just curious. In the end I pretty much treat my truck like a 5spd manual tranny.

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....

I thought it was a great feature. It doesn't do it any longer though with my 35" tires.

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.

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.

And I too, like to shift for myself. :D Just much more fun to drive that way... And yeah, I know all the townies will chime in with the old "my left leg gets tired in stop-n-go traffic." Sports cars ain't meant for stop-n-go traffic. Nuff sed! :thumbsup:

It amazes me how many people have absolutely no idea how to drive a (standard shift, straight drive, stick shift, call it what you want) manual transmission equipped vehicle. I'm sure there are some out there who don't even realize they exist!! I think alot of it has to do with society, in general, being a bunch of lazy bums. It's just another example of a manufacturer catering to our so-called "needs".

I'm looking at moving into a superduty diesel and was considering a manual tranny. It turns out Chevy/GMC doesn't even offer one anymore!! I couldn't believe that... what a funny sign of the times.

The manual tranny on the F-150's for years (after 1993) was the one from the Mazda mini-pickup. It was actually the weakest link in the chain. Towing with the automatic F-150 was 7200 lb, but with the manual was only 3600 lb.!!!! Nothing else was different on the truck! It was ok as a daily driver and lasted me 180,000 troublefree miles, but it's not a work tranny, that's for sure!

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.

I like the way the Titan stays locked up when you let off the gas. It saves on brakes. Not very often do I want to coast. I usually only want to speed up, cruise, or slow down.

I believe the transmission only downshifts when the cruise control is on, and only from 5 to 4. It definitely doesn't do it at every stop.

I would love to get rid of the slush box and have a manual transmission in a Titan.

did they have this in 04? i'm not sure i've felt my truck do this... although i don't drive around townin D I use 4 for anything under 45mph... i don't need to be in D unless i plan on really hauling ***...

i've noticed that they started putting automatic's in 18 wheelers mainly because they've developed the technology to do so. for years it was an artform shifting, right throttle, gear, road speed... i asked one of the drivers of the new automatics how he liked it and he said it was great... however his gas millage dropped severly.
