[Healeys] overdrive

[James Shope]

got the gearshift adjusted in the bn6 and decided to let the engine run in
gear for a few minutes.  all of a sudden the engine slowed down and stopped.
thought i had sticking brakes but discovered the overdrive was very hot, while
trans was still cold. could not turn propeller shaft in direction for forward
movement, but reverse direction rotated smoothly.  car is on jackstands so was
able to check everything easily, but am stumped. od turned easily both
direction previously,  and only work i had done on it was install a cam and
fix the oil pump, which had been stuck down.   any ideas.  will pull it next
week to check it out, but am flying blind.    healeymanjim
