Does TCC disengage in 3rd gear?

Jerry, disconnecting battery will do the opposite of putting vehicle in readiness state, the only way to get in ready state is by drive cycles or a technician with a good scan tool, to make the monitored items run on command, which can put them in ready state.

How can I reset my service engine soon light on my 1997 cadillac deville off??

There is a reason that it came on. Something has malfunctioned (usually an emission control device) to casue the light to stay on. A trip to a place like Auto-Zone or O'Reilly's can get you the FREE use of a diagnostic tool to reset the light. It also downloads the codes to tell why it was set in the first place.
Good Luck

Service emissions system

That will not pass a PA state emission inspection. Don't know what state your in. Take the car to Auto Zone and they will read the trouble code for free. They will let you know what part probably needs to be replaced. You can then buy the part and do-it-yourself or take it to a mechanic knowing what is most likely wrong with it.
