What your describing is going to be extremely tough to fix without actually hearing it. Ok, that said.

Our 2005 T+C has a scrunching noise. And has for some time. Needs upper strut mounts I just haven't taken the time to fix yet.


If your suspecting torque conv / trans issues, drop the pan for a look see. Pull the filter and open it up ( Do NOT use a wizz wheel to to it ) Ck for heavy particles in the fiber.( it looks like heavy black sand ) If there, Plan on dropping it and replace the torque conv soon

But what your describing sure sounds like coil pack or plug wire failure.
