It's not horrible, it is a ton of time the first time around.
Tools: you can not get around needing a clutch compressor tools and the 3rd/input housing teflon seal resizer. The rest of the stuff can be worked with. I found that a trans mounting bracket on the engine stand made things much easier as well.
The seals are the main PITA as some are in places that are difficult to get to, slow and steady...they can be done. Clutch pack clearance is another thing to keep in mind. You may need/want different steels to take up some of the added space.
There is some valve body stuff that it would be nice to send out to Dave at TEP. It's $350 for that. If you add up the parts, they come to ~$300.
Having the VB and channel plate work done from Dave and allt he other parts semi cleaned and inspected. My first time reassembling took me a full 24 hours. That's a pretty high number, and you can shave a lot off it if you don't pull the seals off everything before the new parts arrive. I had to match things up and it took extra time.
