My '90 Suburban has a turbo-350 tranny behind its 454. I am considering putting a 700R4 tranny in its place, to help me with my MPG a little. Is the 700R4 a plug and play swap? I did a search of the forums, but I did not see anyone else who had done the swap. Is there anything I should look out for?
