Dodge Caravan transmission lock-up

I have been watching the SG in my 2003 Caravan 3.3 and noticing the increase in mileage when the transmission locks up. This happens about 42 MPH. This is a little fast for around town driving. Does anyone know what parameters the computer looks at when it locks up and if any of these parameters can be affected by altering sensor inputs without affecting driveability or mileage? This aproach seems to have the potential for significant improvements in city mileage.
