    I drive an automatic 06 and I have a habit of placing my car on neutral when I need to make a stop or when I drive downhill for a long period of time with out making any stops. Is this okay for my engine/transmission?

    touche!...never scanned that entire thread...will read it throughly tonight though now that it has brought new info to me!

    but the injectors still turn off when coasting, where as they are live when in neutral, correct?

    I think that was the "agreed" answer. I's been a while since I read thru that thread.

    Yes it was concluded that the injectors stop when coasting in drive, but they're active in neutral. One scanguage owner reported that if you coasted downhill for an hour in neutral the truck would consume 1.3 liters per hour of fuel.

    Based on what I read though, my opinion is that by coasting down very long hills in neutral allowed momentum to carry the truck further and offset the fuel savings by keeping it in drive. ASE, and others, (myself too), don't recommend shifting in neutral for city or regular driving.

    I once recieved some good adivce for not putting the truck into neutral at a stoplight. This is especially true if you're at the front of the traffic light. If someone rear ends you, you'll fly into cross traffic with greater force than if the the truck was in gear.

    Regarding the linked thread in post #2,

    No mechanical damage should ever occur by shifting into drive from neutral or vise versa, this was because the transmission and engine are electronically controlled.

    There was a big discussion of whether or not the transmission will cool itself if it is in neutral or not. It will. And that is why some owners manuals state that the operator should put the trans in neutral and rev the engine if it is overheating like at a stoplight or in traffic.

    FWIW, I don't think the injector shutoff is the same in the manuals. I've noticed that the mpg reading on my gauge shows no difference when I'm coasting in 6th or when I'm coasting in neutral. Plus the gearing on the manuals is so high, the truck slows down whereas in neutral it can gain speed (or as you've stated you can coast further). I've run down one stretch of road where 6th maxes out at 75 mpg whereas running in neutral can climb to over 105mpg (depending on coasting speed).

    Wow. That is really interesting. In the referenced thread nobody had reported anything on the manual transmissions. Having a gauge like yours is extremely helpful. Very cool! :)
