Q: tbone wrote who is digging for anything getting caught in your own spin again i see. you were the one making the claim of them being better for the past two years what about prior to that theyve had good years and bad. same as all other manufactures. ive yet to see anything youve said that suggests that dc is any worse than any other. i have posted sources to suggest they are now better than average. thats a good thing but you being the liberal in the crowd finds the negative in it. good grief. where did you hear this i be that there are as many sources that say different. jdpowers which relies on consumer surveys of which i have participated in many times. i find their reports far less biased than consumer reports which is anything but consumer reports. edmunds surveys matched jdpowers but i do not know the credibility of edmunds. now you can trash talk any reports i suppose but then your assumption regarding dc isnt substantiated in any credible way. where did i say that dodge was crappy dc -3 sounds kinda crappy. or is -3 doing pretty good what i did say is that they are not the definition of perfection that many in hear seem to believe. please state when and who made such a claim. or did you just make that up by extrapolating what was actually said .

in driving. shop which gave the code said it could be 1 torque converter torque converter has no sensors and cannot throw a code. 2 front transmission oil pump pump has no sensors and cannot throw a code. 3 torque converter clutch solenoid or transmission tcc solenoid can cause a code but a corresponding change in drivability should occur. a quick google search said this could just be a bad speed sensor. any ideas id go with that. tom lawrence seems to be on top of the codes and could tell you for sure. -- max give a man a match and he is warm for a short while. light him on fire and he is warm for the rest of his life. i have a 1999 5.2 2wd durango with 118600 miles. recently the check engine light came on and has stayed on. now i dont notice any change in driving. shop which gave the code said it could be 1 torque converter 2 front transmission oil pump 3 torque converter clutch solenoid or transmission a quick google search said this could just be a bad speed sensor. any ideas .

um no. air is elestic. itll always be the same volume. different density but same volume. um no. the volume is based on the amount of air that manages to get into the cylinder in any given cycle and there is nothing all that consistant about that. if this were true there would be no need for a throttle body. youre confusing volume and mass or moles... the volume of air in the cylinder is always equal to the volume of that cylinder unless its a complete vacuum which doesnt happen. a gas will always expand to fill its container. sorry tom but you are incorrect here and your vacuum description proves that. the volume of a cylinder is a dimensional measurement of space within the cylinder while the volume of a material whether liquid gas or solid is the amount of that material. within the space if i were to put 1 molecule of oxygen into a 20 cu in container it most definitely would not have a volume of 20 cu in. it would take up the same molecular amount of space that a single oxygen molecule always takes up it would just be in a 20 cu in space. whether a gas is at 2psi or 20psi if its in a 20cu.in.container its volume is 20cu.in. no unless the pressure was zero at sea level it would be x cu in of gas compressed or decompressed into a 20 cu in container. -- if at first you dont succeed youre not cut out for skydiving .

mrs.nospam@gmail.com wrote the exact information they gave me was code po720 - torque converter clutch no rpm drop at lock up i was surprised to see all the quick responses - torque converter lockup is pretty easy to test. drive on the highway at a steady speed. tap the brake pedal very lightly just for a second. this will cause the tc to unlock causing the rpms to go up about 200 then immediatly drop back down if things are working normally. .

the exact information they gave me was code po720 - torque converter clutch no rpm drop at lock up okay - then theyre not being dishonest they just looked something up wrong. p0720 is an obd-ii standard code meaning it means the same on all obd-ii vehicles as opposed to a manufacturer-specific code which could mean different things on different vehicles and that code refers to a problem with an output speed sensor. .
