Dear GTO:

Probably the Direct Drive Clutch or the High range clutch slipping from too little pump pressure resulting from worn bushings.

At 45-50 mph the motor is at its optimum torque to rear wheel range and so stress is highest. If you take the pages from the manual to a transmission builder they should be able to hook up gauges and check the pressures on the road.
