Default Mileage went down with trans rebuild?

My father had trans rebuilt in his truck and now the mileage and dropped about 3 mpg. We figured with time it would get better. 13,000 miles later not better. 700r4 in 92 silverado.

Check that the square plug is pluged in on the drivers side near linkage . If it is check that theres power 12v to the outside terminal closest to the front on the plug if not check fuses. Sounds like you may not have lockup working ,
