I have a problem that I just can't seem to figure out. I have a 2002 Dodge Ram 1500, 5.9L. When it is cold outside (40°F or less), and I first start the truck, get it up to 55 or 60 mph, and come to a slight grade with the truck in OD, I begin to get a shake or vibration. I have to gradually get into the gas for this to happen. If I step off, it stops, if I get into it a little quicker, the torque converter unlocks and everything is fine. Take it out of overdrive with the switch, and it is fine also. At any rate, about 10 miles down the road, once the truck is warmed up, everything is fine once again.

Has anyone else seen this problem? If so, how did you fix it?

Any help would be much appreciated.

Thanks

 

sounds like trans fluid is not warmed up, ever changed it?

 

The fluid was changed at 50,000 miles in the spring of '06. The truck now has 86,000 on it. I have had the truck since '05, and this winter is the first one that I have seen this problem.

 

i would try changing it... cant hurt right. if that doesnt fix, well..... ill have to think on it

 

u joint might have play check by leaving in park(duh) and twist the drive shaks should have no more than 1/2 in play,
i was gonna do mine there only 20 bucks just cause theres no grease fitting. why would they do that

 

Our 2000 Dakota Quad 4x4 did that just a couple of weeks before the tranny went.
