Good grief, it's not like I'm coasting for miles on end, such as being towed!! And there is no "slam" when shifting from N back into D. Can't even feel it shift back into D. AND, my rpm gauge shows less rpms when coasting in N compared to "coasting" while in D.
Actually kevin, it is probably "possible" to not coast faster in N compared to D, the faster the vehicle is going, the more rolling resistance there is, so at some speed, there will be no gain in coasting in N., and obviously there is a need for enough decline in the road to over compensate for the rolling resistance that a vehicle has.
Obvious that I'm livin' on the edge according to some of you guys. But kind of like drinking milk that is past the expiration date, I like living on the edge!!
here's a experiment for you guys to try, find a peice of road and at a certain speed begin coasting in D and see how far your truck makes it before it stops, and then do the same thing in N. I'll bet that your vehicle will make it further while coasting in N, because your engine will slow your vehicle down quicker while in D, do to some engine breaking effect.
WRONG........EVERY car made coasts faster in neutral, you are not using the engine compression and drag when in neutral, its impossible for it to NOT coast faster. WHAT MOMENTUM are you referring to?? Its the weight of the vehicle rolling down a hill that makes it coast faster, minus any drag from air, tire rolling resistance, and any drive train drag, and engine compression. The engine is IDLING whether you have it in gear or neutral, so COMMON SENSE tells you that if you coast faster in neutral you are going FURTHER on the SAME amount of gas.....!!
Ok I guess I was wrong, probably because i dont fully understand all this stuff, but you seem to. But i do have a question about this theory, if your coasting down a hill with momentum or just moving forward for that matter you still have momentum. So if you put it in nuetral, the engine is on its own, in theory free from the wheels so nothing is keeping it going. But if its in drive, the momentum keeps the crankshaft turning. So if this is right, wouldnt that keep fuel consumption lower if the momentum helps the crankshaft than in nuetral?? If any of this is wrong id like to know because im still learning all this stuff.
And either way, whether theres no bump when you put it into drive at 1500 rpms, it cant be good for the transmission, it may not be bad, but it seems like doing that several times each drive could have a negative effect over time.
The crank shaft doesn't keep the engine running, that's what gas, air, spark plugs, and compression do. In your way of thinkin', what keeps the engine running when in P?
What is harder on the transmission is when someone races from stop light to stop light!
doing neutral drops while in motion will take its toll, plain and simple. you may not feel it right now, but if you keep doing that, youll find out soon enough. automatic transmissions are not built for that. hence the name "automatic." youre supposed to let it do everything for you and leave it alone. if you want full control, look into getting a car with a manual transmission.
just because it hasnt broke down on you yet doesnt mean it never will.

EVERY vehicle coasts further in neutral..>I did experiments in college in my Technical physics class, regarding coast down measurements. Its air drag, frontal area, tire rolling resistance due to tread and weight on tire, and drive train total drag...Thats what slows the vehicle down. Having it in gear makes quite a bit more drag, as the engine compression is slowing the vehicle also..it depends a LOT on gearing etc.....imagine being in SECOND gear....you gets lots of engine braking...same with vehicle with numerically high axle ratios.

It depends on what the fuel system is doing. If as I suspect the '93 doesn't have fuel cutoff while engine braking it is still providing fuel to maintain idle and continuing to add some power and therefore may not slow down as fast, especially if the idle is high.
