Question: Is there a 5 or 6 speed auto that would fit in place of the 4 speed 4l60/700r4 transmission?

Well i have a 1990 gmc sierra with a chevy 350 that has a 700r4 transmission 2wd and i would like to know if there are any 4speed with overdrive, 5 speed, or 6 speed transmissions that would be able to fit to my current engine? I would be willing to get the computer and any other parts that go along with it, i just want to know if there are even any other transmissions that are available, but i do realize that this is a very good transmission.
