Q: if you think about it for a minute youll realize that the whole idea behind tsbs is to disseminate info not contained in the service manual. if the limp mode/limp-in mode were addressed in the fsm there would be no need to rehash it in a tsb. if you think for a moment after reading the fsm and the complete description of operation you might also come to the conclusion that there is no limp home mode. this is because it specifically details what the pcm is capable of doing. perhaps because they choose not to name this condition in the fsm or maybe it is an unexpected condition that happens enough to be given a name. if these things didnt happen then there would be no need for any tsbs. -- if at first you dont succeed youre not cut out for skydiving .

thought the new ford 6.0 was aluminum headed too from what i hear the powerstroke 7.3 was a much better engine. my big concern would be with automatic transmissions. they all seem to be questionable. of all the automatics excluding the allison the ford 4r100 is the better unit its now the 5r110 as they started using the od unit to give an extra gear between first and what used to be 2nd and is now 3rd under heavy loads built right with lots of external cooler and a converter matched to the useage its very good .

you cant ignore acceleration. thats what g is after all! i understand that... but what i dont want to get into is how a mass can actually be considered weightless- that is when its acceleration is exactly that of gravity ie. falling at 32ft/s2. i also dont want to get into the fact that an objects weight will increase if its accelerating in the opposite direction of gravity ie. the shuttle pulling 4+g during liftoff... astronauts weighing 700lbs.. the principles being discussed here are all with the mass at 1g. but see... now ya made me get into it! a ship would be pretty heavy yet it generally floats on water. not because its lighter than the water but because it weighs less than the volume of water it displaces. same for a hot air balloon. and the vast majority of us understand that concept. tbone will claim that the ship is weightless because its floating... the ice cube and water example is a bit more complicated since water has a rather unusual property it gets more dense as it cools like most stuff but then just as it approaches freezing it suddenly gets less dense! well yes - but its an easy example to comprehend and if one had a small kitchen scale one thats easily reproducable. the fact is that the ice is slightly less dense than the water therefore it floats but adding an ice cube to a glass of water sitting on that scale causes the scales reading to increase. simply amazing given how that ice cube is supposed to have no weight when its floating that is because it doesnt but the concept is simply beyond your grasp. -- if at first you dont succeed youre not cut out for skydiving .

the ford diesel is a navistar and has some problems since its introduction. the gm diesel is a joint venture with isuzu and is an aluminum headed design which can be problematic. the most important difference regardless of the design details is the main design feature. the dodge has a cummins inline six the others are a v8. ford navistar v8 7th year of manufacture has had seal problems on the turbo and generally is not the leader of the pack in this race. not a terrible engine and is a reputable manufacturer. transmission is typical ford design which is to say more complex and more electronics than really needs to be. result is that it can be a bastard to fix if it fails. chevy isuzu designed v8 5year of manufacture aluminum heads which are a problem on gasoline engines are applied to the high compression world of diesel with mixed results. one thing is sure just as in the gasoline world the aluminum head on an iron block is a point of gasket failure and the added stress of high compression is no help. transmission is the much talked about allison but word is running around with some reliability that the alllison can fail at the 60k mark due to various reasons. i suspect this may be for reasons other than design but this allison isnt as good as the allison reputation from what im hearing. dodge cummins isbe with more than 20 years of manufacture starting with the b5.9 then bta 5.9 then isb and now isbe engine design is from a pioneering manufacturer that makes only diesel engines. design has had 20+ years of evolution. inline six is design type that is proven to make the most torque from the smallest displacement. engine is heavy in all respects and has a longer life expectancy to first major overhaul than the others. trans is the proven 48re which has 20 years of manufacture on the od unit plus 20 more for the main transmission. overall if you plan on towing a lot the dodge is the one to get. -- max thought the new ford 6.0 was aluminum headed too from what i hear the powerstroke 7.3 was a much better engine. my big concern would be with automatic transmissions. they all seem to be questionable. al 2004 600ctd 4x4 six speed. .

why did you snip the wires why didnt you buy a plug in harness for $10 from the stereo store radio shack autozone even evilmart has them wire it up color for color to the stereo tape off unused wires plug it in and wa-la you are done no snaps crackles pops i tired to put a new aiwa cd player in my 1990 dodge b150. everything weems fine except for one small problem. there was one wire from the dodge harness that i couldnt figure out what to do with the orange one that was on the same block as the power. so i left this one alone. on my new stereo there was a yellow wire that seems to be for the memory i connected it to the pink/red wire and the stereo works and hold time and presets. the real problem is this when i turn on the headlights in this configuration it blows fuse 6 horn guage lights and rear lights-but not brake lights the new stereo doesnt have the dimming capability of the original unit... how do i fix this thanks harry .

ohh.. one other thing. i wonder if the fan is considered part of drive train and would be covered under the 7yr/70k mile warranty that dodge offers. i guess id have to put the inop fan back in and drive it to the dealer if it is.. -jr .

lol actually just about all of that is true. the 5lb dumbbell does weigh 5 lbs you mean its not weightless because its being supported in the air by you amazing... and if you were to put it on the scale that is the reading that you would get unlike helium gas. you just cant get your head around the fact that 1000scf of helium gas has a weight of 11.25lbs. can you since i am exerting 5 lbs of force to maintain the dumbbell in position an equal and opposite force yeah - its called the weight of the dumbell - just like the weight of the ice cube exerts a force on the water which is reflected in the overall weight of the glass. your notion of well since its floating it has no weight or well since i cant put it on a scale and measure its weight it must be weightless is just completely and utterly rediculous - as pointed out by everyone else whos been involved in this thread. but thats ok tom... you stick to your guns - no matter what. at least youre committed or should be and thats an admirable quality. im going to bow out of this now... you get the final say here. please - make it a good one. the stage is yours and the musics started. make sure your shoes are on tight your top hat is on straight and your cane is in hand. make us proud tom!!! .

funny... a concept so simple i didnt think to question him on it till you brought it up. i wonder where he thinks atmospheric pressure comes from in the first place i mean - somethings gotta weigh something to generate that 14.7 pounds per square inch... he forgot one basic fact of physics... everything has weight. this basic fact is why man started wondering why birds could fly. there had to be a countering force..... w r o n g!!! everything has mass but if you were in a point in space where there was no gravity or the force of gravity was negated by another force perhaps the gravity of another mass there would be no weight. -- if at first you dont succeed youre not cut out for skydiving .

i already said that the glass would weight more. i guess that reading just isnt your thing. now weigh the ice cube while it is floating in the glass and tell us the results. that procedure would be the following 1 weigh glass of water 2 weigh glass of water with ice cube in it. 3 subtract results of line 1 from results of line 2 4 difference is weight of ice cube while in glass of water. wrong what you have measured is the force being applied by the water to make the ice weightless. you do remember that equal and opposite reaction law of forces dont you to measure the weight of the ice cube you need to take a reading directly from the ice at its present conditions. wow you are wrong it weighs something its not weightless how can this be it cant but i can see that you are far too simple minded to understand it. btw you were still wrong on your cylinder has the same volume regardless of the position of the piston bs but nice spin to get away from that point im impressed. -- if at first you dont succeed youre not cut out for skydiving .
