how hard is it to rebuild a 93 4l80e transmission

ok so i have been looking for a used transmission for my truck since my reverse went out. my transmission is hard to find. i have went to transmission shops in my area and its 2000-3000 for a rebuild. i just dont have that type of money. i am wondering how hard it would be for me to pull the tranny, and rebuild it myself. i have no experence with transmissions. i can find used transmission with 150k+ miles for 600 bucks but dont think its worth the risk of buying one and then in a few months it goes bad.

i have bought used trans with good luck in the past. if the price is right it might be worth the risk. you don't have to stick to a 93. an updated wiring kit can be had, improving the harness that is prone to failure. how did you determine yours was bad? electronic parts can be replaced by you in just a few hours. there is also ways to get back on the road without a lot of coin. all the info is in this thread. i have never looked beyond the pan parts but have heard it isn't hard.

my reverse slowly started going out. and when i went to work one day it just stopped working. buddy of mine said the tranny was not good and needed to be replaced
