I just recently pulled the 4R100 on my SuperDuty by myself in the driveway with it on the ground. Biggest obstacles...it's a big freakin' transmission. My truck is lifted 4.5" and I jacked up the passenger front tire and still couldn't get the trans out from under the truck on the transmission jack. Even with a transmission jack make sure you secure it to the jack somehow...IT IS HEAVY. Overall it wasn't bad and I managed to get a new flywheel in and get it up and running. That said...I will do the transmission again when it finally goes out. Just take your time and be careful. Crawl under there and look at how you are going to access all the bolts and if you have the correct tools. I used a lot of extensions and joints and flex head ratcheting wrenches.
