Hey Everyone.... Your input on this subject will be greatly appreciated.

We just purchased the truck, and for the most part we are thrilled. We have less then 500 miles on the truck, and had to do a run on back roads yesturday that didn't allow us to go much over 45 mph, and it pointed out and issue or what i think is an issue.

When traveling at 40MPH, with an RPM of approximately 1250-1500 the the truck studders(when not excellerating). The RPM doesn't change when its happening, and I can't tell if the truck is having a hard time figuring out what gear it should be in, or if its simply missing a gear in some fashion.

I would like to hear if anyone else has had this issue, or would possibly have some input. I have to call the dealership tomorrow, but I would rather have as much knowledge as possible prior to speaking to them.

thanks again...
