Corey, hate to sound rude, but does it hurt to sitdown? 4500 is enough for an Allison!!! 2500 should get you a gm reman installed. I wouldnt do anything until you let me know the code(s) There is codes for the tranny as well... Let me know what they are please before doing anything drastic

Code 1870 is Trans slip detected. usually caused be high tcc slip which is not noticable to the driver but the pcm picks it up. How does the tranny work? just a code in it? any debris in the pan?.. There is an aftermarket valve to put in the valve body made by sonnax that can cure it if its caused from excessive tcc slip, this code will also cause harsh shifts as it commands max line pressure. If the trans operation is ok and no problems other then ses light on, you can fix it for a few hundred bucks tops.
