I have a 1993 k1500 Suburban with a 10 inch lift, 4.56 gears and 37 inch tires. Going on my third transmission in 4 years. I would like to upgrade to a 4l80e transmission but do not know exactly what I will need for a wiring harness and or computer or any thing else. Sub has a 350 with a 4l60e automatic already.
