Resetting the Computer Module?

Resetting the Computer Module?
To All -
I have read a lot of posts regarding resetting the computer module by unhooking the battery. I have some questions:
1. I have a '95 F150 XLT with the 5.0 engine. Does this advice apply to this model year?
2. If it does apply, exactly what is lost in the computer when it is reset? I have read things like former driving patterns related to transmision shifting and control and shift points.
The reason I ask is simply because I don't like the way my truck (4W70R transmission - 3.08 ratio) shifts into OD when going 65-70 MPH and going up slight inclines, with no load in the truck. I am most concerned with effeciency and fuel economy. Will resetting the computer - if my truck has one - help this out?
Thanks!

Thanks for the reply.
If I do erase the KAM, what will this do from a performance and economy perspective? I am getting almost 15MPG in city driving. Is there a chance this would improve? Or, could it get worse? What are fuel trim tables? Over how long of a period does the KAM accept new input/experience to build it's profile? This is all news to me, and I do appreciate the help!
Thanks,

My owners manual says it takes 100 miles after a reset occerence before it has learned everything. I was tinkering with mine 2 weeks ago and had unhooked the battery for a while. For 2 days afterwards the performance and fuel mileage sucked while it was in default. Now I am back to normal and have a little harder shifts as I had not set it to my driving since I bought the truck.
