100 Auto Trans Woes

[kolson@statestreet.com]

     Flipping through my owners manual, I noticed that if there is a 
     "fault" in the auto trans control module, the transmission will go 
     into "failsafe" mode and will either a.) shift roughly or b.) require 
     manual shifts through the gears by moving the lever.
     
     I've also read in the Dyment manuals that each time you disconnect the 
     battery, you'll have to reprogram the transmission control module 
     somehow.
     
     The auto trans in my '91 100 shifts roughly and I have had the battery 
     disconnected. Has anyone experienced similar problems? Anyone know how 
     to reprogram the transmission control module without a visit to the 
     dealer?
