I have a 1993 Silverado I am swapping a 2001 5.3 into. I have heard the non-pwm transmissions wont work with the 5.3. I can't find much info on this subject that is helpful. I have read there are ways to make it work. I read you could swap a 1995 and up internal tranny harness into the older style transmissions to fool the 5.3 computer into thinking everything is correct. I just need some help on this...
