Rik, suggest you spend some time with your trans and with the hydraulic diagrams and figure out how different pressures get where they need to go. Many times the bushings are necessary to get oil under pressure where it needs to go.

For example, the torque convertor is filled (and pressurized) through the groove in the center of the bell housing bushing. If you replace that with a needle bearing, you will need a whole new path to fill the convertor.
