4l60e behind carb

I have a 1994 k1500 with a 4l60e I pulled the motor
it's now a carburetor tranny is doing weird stuff
sometimes shifts fine others like in limp mode I do
not have the tps hooked up because it's carbed
now will thus effect it in any way have the oil
pressure temp hooked up but switched to a hei set
up any help would be greatly appreciated
