I just bought my 100% factory original 2005 SRT-4 ACR with 5k miles not even one week ago, and immediately I noticed some significant shifting problems. I just read this thread and decided I needed to take a look, because I thought just maybe it's related.
Take a look, I made this MPEG video with my digital camera (streaming download, 16MB total), just maybe it may find its way to Chrysler so they take this issue seriously.

This obstruction was so obvious, I almost felt afraid to drive again it until it was remedied. After relocating the brake light wiring, I gained roughly 1 FULL INCH of pedal travel. I've driven it roughly 20 miles since relocating the wiring, and utilizing this extra last critical inch of pedal travel, I've noticed a very significant improvement in ease of gear engagement, in ALL gears.
It is my understanding that 2005 models have significantly more gear engagement problems, and also 2005 is approximately when Chrysler started putting this plastic "tab" to shield the wiring from direct contact with the pedal. Is there a coincidence between this extra tab getting in the way and the gear engagement problems?
If you have gear engagement issues, I'd highly, HIGHLY suggest inspecting whats happening here on your car.
Here is a photo... Note the distinct vertical line in the fraying, and the "goo" stuck to pedal shaft. You can clearly see where they were coming in contact. The MPEG video shows it actually happening.
