What would cause a 4R70W tranny to shift early into overdrive? It seems like 3rd gear has gotten shorter

The shifting into the gears has recently seemed harsh and sloppy also. I am just hoping that all this will be solved with the JMOD and new converter and I don't have internal issues. There is no slipping of the transmission that I have noticed. Some of the sloppiness I am almost sure is attributed to the rear differential and possibly tranny mounts all of which are also getting replaced when the car goes in for the makeover. <crossing fingers>
