There could indeed be electrical issues helping with the failure or just could be a bad 3-4 set in the stock one and some failure in the built one. First thing though you have to get a working trans back in the car then check a few things out

the new stock one is under warranty but i dont want to pull it if i dont have to. is there any computer work i need to do if i do replace it?

Well you just need to verify Line presure is really it and oddly clean your MAF sensor

i was reading a thread about a guy losing 2nd and 3rd and someone said unhook the battery for 15 minutes and see what happens is this a possible fix if there is something electrical is wrong with it

and in neutral if you rev the motor a little bit you get a whining sound coming from the tranny any ideas?

The whinning sound could be a filter plugging...from the burned clutch material..hope this helps

when i got my ta it shifted like crap. i went out, got some MAF cleaner, electrical contact cleaner, and went to work. i unhooked my battery for 15 mins, during that time i unhooked all of my plugs from the throttle body and sprayed them and took off the MAF and cleaned that. put it back together and it feels like a new tranny. i dunno if thatll help, b/c of the "gone" 3-4, but its worth a try.

I expect that supercharger has laid waste to your 4L60E.Again! Take my advice and go ahead and get you at least a Stage 2 Performabuilt. Running a stock 4L60E on your car would be a waste of money as it won't ever hold up.
