I, like you had never rebuilt a tranny. I decided to take it on several months ago with a buddy who agreed to help. They are as simple as a tranny can get. Collecting the 2nd/3rd grear synro hub plus new engerizing springs proved to be a task as they don't make them anymore. A couple of special tools are required like the wide snap ring pliers, No tool necessary was expensive and adds value to my toolbox for the next job. I used the large service manual for my year of truck. It covered the tranny quite well. There are several guys here that helped me at every stage and when I did something wrong. I have around $200.00 in parts for the rebuild which included the $115.00 for the synro hub. Then needle bearings are a pain but with grease and patience will go back in, just be sure to count them and not leave one in the bottom of the tranny. There is a big grear set in the bottom of the tranny that I didn't have to mess with and most likely you will not either. Good luck
