#7 of 41 2007 DODGE 2500 6 SPEED Auto by dpantekoek Oct 16, 2007 (9:24 am)
I am having issues with the 6.7L engine and transmission as well. The oil change required light randomly lights up and has to be reset, and it is hard starting compared to my old Ford power stroke diesel. The transmission though has me worried. If we use the truck in tow haul mode, (We often do, we bought it to tow the RV.) The transmission starts making loud clunking sounds which one can feel in the cab. When we switch out tow haul we continue to get the clunks, until the transmission is rebooted and reprogrammed for learn mode. The dealer says this is an issue that they cannot repair until Chrysler develops a flash that fixes it. I have spoken to Chrysler and they have no eta for the fix. I got the impression that they really were in hurry to fix the problem, and really did not care if it ever gets fixed. The Dealer service department told me not to worry about it, the problem is there; but it will not hurt anything. (I am thinking it might be time to start looking at other trucks, towing 10K pounds on mountain roads with a defective transmission does not sound smart to me.) Chrysler really needs to step up to the plate on this one, they told me to quit calling them and work with the dealer instead. I for once in my life feel sorry for the dealer. I wish he would have disclosed the problem before I threw all that money down for the truck. Replies to this message: lafs2 (Jan 09, 2008 12:15 pm)

Have many problems with fuel milage, squelching radio, hard shifting when in tow mode mainly when it down shifts if were on icy road would cause a skid out of controll sitchuation,early oil change indication , leaky rear window only on ocassion,and no start several times pluss other minor things and all I get from dealer is cant duplicate problems so dont attempt to fix other than reflsh computer which I find is only a temporary fix for most problems.they wouldnt even replace the radio they made me go buy a new one how messed up is that. if any one has any solutions please write Dan Springfield Oregon Replies to this message: jacarroll (Oct 29, 2007 7:16 pm) jr14 (Nov 05, 2007 9:05 am)

Replying to: rohrich (Oct 28, 2007 4:50 pm) Hello, I have a new 2007 3500 with the 6.7 diesel. I have been very happy so far, although I only have 1700 miles and the "oil change required" light is on. Dealer service acted like they have never seen this. Scheduled it to go in 2 days from now. Why is this light on after 1700 miles...and is this just a programming error? I am wondering after all of the problems I am reading about on these posts??? JR- Portland, OR

Replying to: rohrich (Oct 28, 2007 4:56 pm) Dan, I have the exact same vehicle, I have experienced bad fuel mileage untill I installed a superchip and it went from 11mpg to 14.5 mpg. Tons of damn power but watch your particulate filter, You can not tow in "extreme mode. It just flat out flys now, "unbeleiveable power". Since we have the same trcuk you can utilize my superchip and save 280 dollars. My truck also shifts hard in tow mode and I have not brought it to the shop yet but I will and let you know. The oil change indicator is only a "reminder" to get your oil changed and it is activated by mileage. To clear you turn key on,dont start , and depress accelerator three times all way to floor. It should clear or do again. Remember it is just a reminder so dont freak bro.. I have not experienced a squelch in my radio though so no help, sorry. I paid 600 dollars for superchip and we can trade back and forth cause it is AWESOME. Good luck bro. This truck has its quirks but hang in there and it will be good. I did not like mine either untill I did a couple things and now I love it. I have done my research on all of this truck. Good luck bro and I have a great dealer in Grants Pass,or if you need..Bye for now..Jon, Cave Junction, Oregon Replies to this message: jr14 (Nov 05, 2007 9:05 am)

Replying to: jacarroll (Oct 29, 2007 7:16 pm) Jon, Thanks for the info on the oil change light, it worked. I've heard a little about the super chip. What's the scoop with it? I am getting 13-14 mpg now but would love to get it better. Haven't had the hard shift issue yet, only 2400 miles on the odometer though. I will be towing a 26 ft trailer to elk camp in eastern OR this week so I will see. Got a call from the dealer stating my truck needs to come in for a reprogramming, something about burning off the soot/particulates quicker thus keeping the system cleaner. JR Portland OR

Replying to: jacarroll (Sep 03, 2007 11:04 am) I own a 07 Dodge Ram 3500 6.7 I have not had any transmission trouble, however a around 5k miles the check engine light came on and the truck ran badly. I made it to the dealer in Washington and they found it to be the EGR valve needed replaced. They re programmed the computer and away we went. Yesterday the light came on again. Now in Coos Bay Or, We are staying about 2 miles from the dealership I took it in and they say its a oxygen sensor, they don't have the parts and it will be a couple of weeks before they can put them in and re program the computer. The truck has 6,900 miles on it .
#16 of 41 Ram 2500 Diesel Please Help me in Australia !! by barnesy1 Dec 05, 2007 (4:36 pm)
Guys I was wondering if you can help me? I live in Australia and am looking at importing a second hand 2500 Diesel Mega Cab, and want to know a few things as I was set on it but on hearing some of the problems am not so sure now. firstly would you reccomend this truck bearing in mind all of the problems that it seems to have ? and also the fuel economy ( or lack of it ) in real terms what is it as I have seen some of the mails on this forum saying that they are getting 10mpg or 14mpg at best is this normal ? as I read from Dodge ( of course) that it did 21mpg I really would be grateful as I am talking about a lot of money here as i have to get it converted from left to right hand drive plus all my taxes and import charges, so i really would be grateful for the guidence. Thanks
