1939 Super 8 overdrive issues. I have an R-11 overdrive unit that works fine for about 20 miles or so and then it will not engage. It just goes into free wheeling. It has worked as advertised for the past 12 years until recently. I can drive the car for about 20 miles without overdrive and then pull the handle to engage and it will not lock into overdrive but, goes into free wheeling.

It seems to be heat related as when the system is warmed up well the overdrive will not engage.

Any thoughts?

Thank you
