I own a 2001 4 door shortbox Dmax with an allison. It was one of the first sold in this area. It has had many problems from not starting when it was unloaded from the truck at the dealer to just yesterday's fix replace a broken turbocharger outlet bracket. I don't think there is anything that hasn't been done to this truck as far as service bulletins or reporgrams to CM's. The truck has 41000 miles of these 35000 has been towing either an 8000 lb jet boat or a 7000 lb snowmobile trailer. My problem is when it gets up to temp. which is just under 210 and the outside temp. is around 85 and above and the rpm is 2600 and above it has a noise. I believe I know what the noise is when the pilot injection shuts off and this is not the same. This is a rattling and if it was a gas engine I would say a missing sound that continues after the pilot injection shuts off. It doesn't seem to affect the performance any, no black smoke, no ses light. I had a diesel tech from my dealer ride with me using a tech II and didn't find any problems. The noise is not intermittent, the tech from the dealer agrees it is there. It is very annoying when passing someone or pulling a long hill. It has not always been there and I hope I can get rid of it. Help would be greatly appreciated.
