A few months ago my 2004 crossfire had a problem at the tail of the dragon and it had to be towed home on a tow dolly (4 hours home). I got the original problem fixed; however, when I got in the car to drive it, the car struggled to move when in drive or reverse. I also noticed the car had developed a constant ticking coming from the transmission ONLY when in drive or reverse. I looked on the forum and it seems no one has posted about this problem before. I have tried different RCMs and checked the transmission fluid level, but no progress. Does anyone have any ideas what can be causing this?

Here are two videos I took of the ticking

 

I certainly hope you had it towed on a flatbed.
If you had it towed with just the rear wheels on the ground, did you remove the driveshaft ?
If not, then you have probably destroyed every bushing/bearing in the transmission.
