The first time I did it was in the early 70s, so none of those companies were around. I think, but have a Ford bias, they are an easy tranny to pull down and rebuild. Like anything, attention to detail is important. The hardest part for a novice would likely be installing the countershaft pin and the bearings. I have an old countershaft pin that I shortened and use it and push it out with the pin I am using. That is something overlooked too many times...the wear on that pin. Depending on how many miles are on it that may need replaced, if it does, don't try to get by with just the bearings....it would be a waste of effort.
Typical attention to synchros and gears while it is apart are always important.
It's been a while since I did one and forgot that you had to pull it down to replace the o-rings...I thought that you could do it from under the arms. But when I refreshed my grey matter with a manual, I see that.
