I have a 02 grand prix with the 3100. Nothing is wrong with the motor just has 83k on it. I have a fresh rebuilt 3400 and a rebuilt 4t65 transmission both with 500 miles on them from my 04 grand am that was wrecked. I have wire harness and pcm for the grand am as well. Can I swap my 3400 and 4t65 into my 02 prix?
