Dodge Ram Van 3500 1-Ton

Q: tbone wrote the pump has a pre-filter attached to the bottom of it and if that union failed it is possible that the pump will begin sucking air at 1/4 tank which would make you think that the gauge was wrong. does the gauge operate properly above 1/4 of a tank yes the fuel gauge works fine until it reaches 1/4 tank. then the gauge just stays there basically. when it was working correctly i would hear a ding and a light would come on the dash saying the fuel was low. using the odometer as a fuel gauge on a full tank it runs out of gas after going 300-320 miles. but yet even when i keep driving it at 300 or so miles meaning it is real low on gas i havent heard that ding in many months. thanks for the info. .

traffic rush hour where the speed is up and down between 15 and 20 km the first dozen or so 1 to 2 transitions are smooth then it starts to get progressively harsher. city driving stop light to stop light is fine no problems. towing a trailer with 3/4 yard of redimix cement had no problems last summer about 15 km on flat roads ive recently replaced the filter and fluid there was some sediment on the pan and magnet but nothing i havent seem before on other tranies. the problem wasnt evident before the fluid change but then it wasnt used in rush hour or on steep hills. the current and the old fluid smells ok but looks like blood murky red. used dexron 3 with mercon couldnt find just dexron. yes i checked the level of the fluid and it is almost at the max mark on the dipstick. so now the question. is there an adjustment that needs to be done or is this a tranie rebuild again had a 68 dart in the 70s with a 273 v8 same problem. after taking it to a tranie shop for a free tare down and inspection then refusing the repair they had to reassembly the tranie and give me the car back in running condition free it never skipped again up to when i sold it 18 months later. they never told me what they did. thanks in advance . 222 309118 ty8mf.6293$yh2.815@trndny01 torque is the force at play and hp is an expression of the work performed. so its not all about torque -- max there are four boxes to be used in defense of liberty soap ballot jury and ammo. please use in that order. -ed howdershelt author um... no. 100ft lbs at 1000rpm is 19hp. 100ft lbs at 6000rpm is 114hp. yep - and back to my f1 example... 270ft.lbs. at 8000rpm in a 3.0l v10 makes 411hp where that same 270ft.lbs. at 2800rpm in a 4.7l v8 only makes 144hp. which engines going to move the same amount of weight faster im almost sorry to have started this if in fact i did. my only point is that torque is the force that turns the shaft. it doesnt matter how fast you turn the shaft it is still torque that is turning it. at no point does the force or even the name of the force change into something else it is always torque. hp never turns the shaft it is an expression of the resulting motion. you must have torque to produce hp but you do not need hp or kw etc. to produce torque. torque is the force at play and hp is an expression of the work performed. .

im almost sorry to have started this if in fact i did. yep... its all your fault everything you say about torque is true - im not arguing that. the initial statement was in reference to someones claim that and im paraphrasing here the ability to pull move a load is all about gearing. i countered that no - when it comes to moving a load its all about hp. weights being equal the vehicle with the ability to generate more hp will go faster. what i wasnt discussing was the ability to accelerate a load to a certain speed. that makes it a much more complicated equation because then youre usually talking about starting from a stand-still which because of the limitations of modern drivetrains requires that the engine be able to produce enough hp to overcome static friction/inertia/etc. everything that resists motion and acceleration at a relatively low rpm. since one component of the hp equation is being limited torque the other component becomes the deciding factor in being able to overcome those static forces. this is where gearing torque curves etc. etc. come into play. if we could eliminate those artificial limitations lets say we have an infinitely variable transmission that would let an engine operate at its peak hp output all the time then that little 800hp 3.0l v10 engine would out-pull a big cummins 600hp 14l i6 in every conceivable measurement 60 ft. times 1/4 mile times top speed you name it. the fact that the v10 would implode itself before the cummins reached full operating temperature isnt germane to this discussion ^ back to my original statement... the vehicle that produces more horsepower will be able to move a given load at a faster overall rate than the vehicle with less hp. and oh yeah.... my dodge is better than larrys chevy - which is where this whole thing started in the first place grin .
