2000 Dakota Quad Cab Transmission issue question.

Hi all,
I have a 2000 Dakota QC 4.7 Auto 4x4. current millage 85,000
When accelerating the truck feels like it has a "shudder", prior to
upshifting, kind of like driving on the shoulder rumble strip. This happens from a dead stop and while accelerating onto the highway, more pronounced when going uphill. Seems to not occur while going downhill or . If I back off of the throttle when it is happening. Otherwise, everything is fine. It just started about 2 weeks ago.
Any thoughts as to the cause? Fixes?

Have you checked your Ujoints? If they are okay it sounds like you make have some clutch chatter. You could start by doing a fluid and filter change. ----------------- TheSnoMan.com

Thanks for the reply.
The u-joints were replaced a couple of years back, but, that doesn't mean they couldn't go out again. I guess that I'm about due for a fluid/ filter change, can't hurt.

not enough info to diagnose this. check the simple stuff first such as u-joints. has it been serviced ever?
remember that on your automatic transmission the biggest killer over time is heat. city driving with the overdrive on will cause a lot more heat. if you are just hopping around town turn your overdrive off. this will provide more fluid flow which will keep the tranny cooler and will prevent the motor from lugging. my trucks actually get better city mpg with the overdrive turned off also. michael

As it turns out, a fluid/filter change made the "problem" go away. Thanks for the replies.

My reprieve after the fluid filter change was short lived...
As it turns out, it wasn't the transmission.
It was the limited-slip differential grenading itself into pieces.
There was a "C-clip" and other large chunks laying in the bottom of the housing.

Gee, a Chrysler 9 1/2 rear not operating properly, imagine that.
