Condition B - Poor Acceleration High Speed

The engine RPM and the car speed have limitations at high speeds. Performance when accelerating from a standstill is normal. The engine may over-heat. A visual examination of the converter may reveal a blue color from over-heating.

If you remove the converter, check the stator roller clutch by inserting 2 fingers into the splined inner race of the roller clutch, then try to turn the race in both directions. The inner race should turn freely clockwise, but may not turn or be very difficult to turn counterclockwise.
