so i got the flashing o/d light last week ,took to shop and long story short my torque converters takeing a dump so they say,(5r44e) but besides a dump in gas mileage runs fine, but i am playing with idea of going ahead and leting them rebuilt it( also i am shooting nick a pm about his bolt ups )

Well ive looked through several threads and want to make sure i got it all
1) beefed up torque converter (place in savannah builds"custom" torque converters)
2) shift kit for firmer shifts(what other benifits?)
3)selnoids..what are my options?
4) run synthetic atf
anything im missing? i have no where to drop this thing and do it myself is why i am leaning to haveing a shop do it instead of nicks bolt up
