1993 Suburban k1500 Transmission upgrade

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.

Cool

besides changing parts for the 4L80E to fit your vehicle, transfer case , drive shaft, you must address the computer and wire issues.


It can be done , the Camaro/ firebird guys use a wire kit adapter to convert from a 4L60E to a 4L80

I knew everything except the transfer case. Does that have to be change because of the difference in the number of splines?

Cool

the output shaft of the 4L80E is larger in diameter. You will need the correct parts in the transfer case for the 2 to bolt together
