the 4.3 uses a larger bolt pattern than the 2.8 so the tranny will need to change as well as the ecm and you might as well change the harness due to the different locations of the same sensors

I have a 4.3 with engine wiring harness and auto tranny that i am selling for 1300 if you can pick up or pay for shipping (Oklahoma City, OK). It is out of a 99 chevy and has under 60,000 miles on it. It is in excellent shape. You would however need a computer which can be found at salvage pretty cheap.
