Quick, probably dumb questions from a transmission novice

A few comments about using special tool.
If you search eBay for this tool, then you will find over 50 listings.
Search terms: Chrysler shifter seal removal tool.
Problem with using the tool on Abodies is lack of room.
Not going to list everything that needs to be removed to have enough room to do the complete job but the most time consuming task are dropping the exhaust and transmission crossmember especially on the v-8's.
Here is a good thread on doing the job. Read post #1 thru #5.
This link is for cbodies where there is much more room to work.
