I broke my transmission I think!
My transmission starting jumping around AGAIN after all the grounds I installed so I decided to titan up the 2nd gear band and as I was turning the screw it made a pop sound and know the screw turns and can go all the way into the transmission it will start to get a little tite?
O and my truck has lost sec gear!!!!!

Has this happen to anyone els and what should I do?

 

I'd consider not driving it anymore. I'm not a transmission guy, but it sounds like you buggered something up in there.

 

Pop sound is most likely you ripping the adjustment screw welds out of the band, OR snapping a strut that keeps tension on it. I asked our trans guy (with almost as many years of chrysler trans experience as I've been alive) and that's pretty much what he said. Time to pull your trans and tear it apart.
