A basic OH is the replacement of soft parts, clutches, bushings, thrust plates, seals, gaskets, o-rings. Basically, it sounds like the transmission is still working the way it was designed to, but because of wear, you are having the slipping and delayed shifts. I would always recommend a new torque converter.
As far as the overhaul, the money is in the labor and not the parts. Parts, with the converter should be around 600.00. Labor will jump that another thousand.
I wish I had a better answer for you, but based on your description, this sounds like the problem.
