If you want reliability go with a Dodge Cummins w/manual tranny. This setup will last forever.

Jim, I would recommend that you get yourself the best diesel on the market, a Dodge Ram with the Cummins B-series engine. I have one and love it. The truck loves to pull, my mileage is running in the area of 15mpg and the truck is not broken in yet (2400 miles). Cummins rates the engine with an average time to overhaul of 400,000 miles. GM will only certify 200,000 on the duramax. Also, the Cummins is a simple, straight forward inline 6. Less parts than GM or Ford's V8's. Just look under the hood of both trucks, which engine looks easier to work on? Also, modifications for the Cummins to boost HP and torque are easy to get and certified by Cummins (although not be Dodge). Check out the TDR for more info . Regards, BTD

I have got several problems with the Duramax. 1. They have not been out long enough as pick-up engines to know if they will last in that application. 2. The service manager told me that they have had two Allison trans in for repair already (out of twenty sold). 3 The dealers around here won't knock one cent off of list price of a Duramax/Allison pickup. 4. GM's other diesel attempts were a joke, 5.7,6.2,6.5 turbo. Ford and Dodge are still using the same (basic) motor that they started out with many years ago and they are proven outfits. I am a GM man and I just laid out close to 40K for a new 1 ton,. It's a Ford.

Did you know that Ford is making a new diesel motor? Its a 6.0 liter with inline injection just like the Duramax. If the 7.3 is so good why make any changes?

Run don't walk as fast as you can away from the GM dealer and buy somethign that the builder will stand behind.

I have a 1999 Silverado that has so many problems it takes an hour to talk about them. Some are: cruise turns itself on without warning to driver and you don't know its on tell you take your foot of the gas and it keeps going. The antilock brakes come in if you hist a TINY bump like a mannole cover, and then it takes forever and 3 days to stop the truck. The transmission is absolute JUNK, they replaced it in Novemeber, and the replacement had an oil leak. Turns out it was destructing itself inside and the oil was comming out the vent so they replaced it again. The next transmission slips, clunks, bangs, starts out in second gear, and vibrates so bad you can't go over 45MPH.

The engine uses 1.5 quarts of oil every 1,000 miles, and makea enough noise that if it was a tractor we would tear it apart to find out why. It pings so bad it sounds like a diesel, and every time they change the oil the magnet is COVERED with metal shavings.

The alarm turns itself on constantly all night long so when i park it I remove the battery cable.

GM has told the dealer to stop workign on it and put a note in the computer system so nobody will work on it under warranty, and they refuse to take my calls. It sounds so bad and has so many transmission problems that I can't trade it off. So now Im stuck with the POS. Now I am spending 1500.00 to hire a lawyer.

Get a Ford or Dodge at least they will fix it if it goes bad.

Everyone makes their share of lemons, but it is a fact that GM is the worst one to deal with on getting it fixed or replaced. I had a GMC in '91 that I filed lemon papers on at 6 months old and it took over a year to get rid of it and I still took a loss. Went through the same thing with the phone calls. No more GM for this guy!!

Sorry to hear of your problems. Sounds like a lemon for sure.

I know a guy that had similar problem with a Ford 250 Powerstroke. It stayed in the shop more than he drove it. And he lived 65 miles from the dealer. He finally filed the lemon law on it and bought a used Chevy and a new Harley.

I OWNED a 99 F-350. The 1st 22K were OK. Had the tranny replaced. Had more trouble at 36,188 miles. Ford was quick to tell me that I was past my 36,000 mile coverage. I spent a year trying to get my truck fixed. Even had a Ford engineer drive the truck. He agreed that there was a problem. (The truck would shake and shudder when taking off). No one at Ford could figure out what the problem was so they concluded that my truck was operating "normally" (Their words). The last communication I had from Ford was that they would not communicate with me again with regards to the problem I was having.
I now proudly owm a 2002 1 Ton Duramax. Ford cannot hold a candle to the power and comfort that Chevy has put into their new trucks. I tell people that the reason I own a Chevy , is because I did own a Ford!!!!

I work for GM, formerly at one of the 350 engine plants. The duramax was designed and developed by Isuzu, which is the worlds leading manufacturer of diesels. If you check out the numbers, the duramax has more torque than Dodge's Cummins and Ford's Powerstroke. I have seen several reviews of the truck and motor, and all have been more than positive. In fact, I believe that the truck and motor just received truck of the year from Motor Trend. I think that GM was embarassed by their previous diesel (rightly so), and are trying hard to put out the best diesel on the market. MO

Get ready to change a lot of head gaskets with those aluminum heads. This aluiminum/ cast iron combo wont hold up on low compression gas engines, what will it do with the high compression of a diesel? You couldn't give me one !!!

I have been reading up on the new trucks (some have some kinda new truck bug) for a month or so. My question is the drive train, do you have information on this. I have heard that E trans in the Ford run $2200+ to repair. What is GM using and how good are they.

Thanks Sam

The new GM pickup's can be ordered with an Allison 5 spd auto which should be good if it is anything like the Allison trans used in busses and medium trucks. I read that it is a $2250 option, but if it lasts the life of the truck compared to going through 2-3 wimpy car type autos,it may be worth it.

And why is there no 10 speed manual setup? With low gears and overdrive. Most real trucks still have manuals, why, I suppose they are more efficient? Anyone have any opinions? I have a close ratio 4 speed (car type) transmission that I had installed behind the 3 speed wide ratio truck transmission on my last 1/2 ton. The combinations of gears was great. could drive it as a 3 sp or get about 6 or 7 usuable bears from low low to high. I haven't gotten around to putting this transmission im my present truck as there is a gas tank to move to make room for it, and I have other more fun and pressing things to do. But I wish I had it.
