This is one of the many reasons a lot of us have upgraded the transmission. The loose fluid coupling is what is giving you the feeling that it is hanging in a gear,with the stock TC it wouldnt matter if it shifted,the fluid coupling would just slip like crazy,wasting your power. To put the power to the ground with an auto,it needs to come out,and a quality tc,vb,and upgrades to match your Hp need to be installed. One drive in my DTT truck would be all you needed to get you on the right path. Therer are several vendors who make good stuff,everyone knows my favorite.
