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?
