After dropping the driveshaft at 70mph and then replacing it, I'm having some crazy transmission issues.

There's a bad shake/rattle while idling in park or neutral.
It almost "stutters" in reverse, if that makes sense. Its like a pulsing power driving in reverse.
Drive gear seems like the best, but still something doesn't feel right.

While idling in park, if I put pressure against the transmission pan the noise and some vibration seems to stop.

The driveshaft dropped and dragged at the front, putting pressure on the rear of the vehicle during the incident, so I'm not sure if the transmission received too much trauma during the incident.

 

Please add your vehicle details so we know what we are dealing with.

 

Well you have a heck of alot going on there and its pretty hard to diagnosis this thru a forum. Reading your other post with a broken solenoid housing and wondering how this would happen...when dropping a driveshaft..
...leads me to suggest you have a look at engine and transmission mounts...
cracks in bell housing of transmission...etc. something suggests to me its quite possible you have some major damage somewhere that you have yet to discover.
a vibration in park or neutral pretty much eliminates the internals of your transmission except for the torque converter and flex plate of course

I'm pretty convinced that the trigger wire was already loose. The vibration of dropping the driveshaft on the interstate was what it took to finally knock that out for good.

Unfortunately, I haven't had this truck long, so I don't know much about its history. The month that I have been driving it, there have been no transmission issues at all, it's actually ran perfectly for its age and mileage. This is my first Dodge truck, but I've already discovered that many of the quirks I've encountered are things people have already experienced and addressed. I'm really hoping that I'm lucky enough to have the same result with this issue.
