These new trucks seem to shut down really harsh when you turn the key off. Last night I tried shutting down while holding the clutch in. Man what a difference. It shut down quiet and smooth. Any drawback to doing this??? It seems like it would be a lot easier on the truck to shut down smoothly....

the harsh shut down is a common complaint. It is said that much of it is beacuse of the dual mass flywheel unwinding. Sounds good to me. I do the clutch thing also.

Cool! I shut down the same way when I got to work. Nice and smooth shut down. Why didn't I think of this before?? I'm glad I figured it out while I only have 2300 miles on it and haven't done any damage to it, I hope....

Must be a DMF issue. I can't tell the difference with the clutch in or out during shutdown.

That's exactly it. There's a guy on another forum who works for the company that makes the Dual Mass Flywheels for our trucks. He suggested it although he didn't know if it would help. He also said that the long crank issues on the newer trucks are caused by it too. Something about the position of the flywheel when the truck shuts down....

I leave the clutch alone when I shut down, 'cause it makes everyone turn around and watch my pile having a seizure...

I always depress the clutch before shutdown on my NV5600. It pulls the clutch away from the flywheel and avoids the scuffing the clutch would get from the flywheel. It ought to be easier on the new dual mass flywheels too.

Man, glad I read this post I asked about the harsh shut down before on this forum and the only answer I got was ya its normal. This site is great no wonder I spend countless hours on it. My wife thinks I'm nuts, I tell her I am just a diesel junkie

I was aware that it was a normal occurance but just because it happens to a lot of trucks doesn't mean that it's good for the truck. I agree that this kind of info is only found on sites like this. Ask someone on the street the same question and their reply will be that Ford owns Cummings!!!!

Yes I spelled it wrong purposely......

Nothing wrong with shutting it down with the clutch in. It's really personal preference. Won't hurt it if you shut it down with the clutch out, just all the extra moving parts in the input shaft stopping along with the engine.

I always have and always will shut my manual down with the clutch depressed. It has to be easier on everything in the transmission.
If that engine will stop quick enough to chirp a belt it could "chirp" the trans. as well.

yeah i have the same problem my friend suggested pushing the clutch in also it seems to be helping alot

I talked to a fella at southbend and asked about it and he said it was a good idea to depress the pedal even if it is a single mass.

lol xlr8r thats what I've been doing. I've asked the service guys so many times about that and the long start times and I always get a deer in the headlight look about it. That and just deal with it it's normal and if you hear a funny sound just turn up the radio, I love that one.

My wife laughs when the truck shakes at shutdown. She calls it a pee shiver.
You should try it with the doors open. You think they are going to fall off.
