4R70W warning light / codes

My transmission seems to be slipping and down shifting a little hard, upshifts appear to be normal. I am going to change the fluid/filter and maybe add some Lucas additive also, but I have not as of yet. The light does work and is not indicating any codes as of now. It is full of fluid and looks to be in good condition so I am a little concerned I have other problems. I have not tried manually shifting it yet (I hardley ever drive it). I was wondering if anyone knew what kind of conditions the computer sets the light off for? Also, if anyone knew what the symptoms of a bad tourqe converter were? Thanks for any help.
