I actually read that guide a few times prior to getting the transmission, but the explanation of the automatic range is pretty vague.
I got a chance to run the truck around yesterday and with a little more seat time, I really love this transmission! With the trannie swap we also had a new clutch put in and it is awesome as well, low force, and no chatter when taking off.
If your running a 1/2 a million mile plus rig with original trannie I highly recommend a re-manufactured trannie upgrade along with a updated clutch and your ride is going to be like new! This is a relatively inexpensive upgrade, that makes a huge difference. Also had the kingpins and tie rods replaced which also made a big difference in the steering.
Can't wait to put some miles on it now.
