The automatics are not all that tough either. There are more seals and take a little longer to do, but, if you can follow a repair manual and lay everything out like you did on your 4 speed build, it's something you can do. There are a few extra tools to make the job easier (so what else is new!) like a clutch pack press or a set of bushing drivers. but with a little thought, you can get around that and make do. You will need an inch pound torque wrench though....
