I have a 92 GMC Sierra, 5.7L, 700R4, long bed. I am getting ready to put a Monster transmission in it and everything else is stock. I know that you can't do to much to the engine because of the computer set-up(or can you?) It has a 5th wheel set-up and a class 3. I want to be able to set-up as a good tow rig. Any websites/suggestions would be greatly appreciated.
