Re: Slipping O.D.

Ed, before you panic, try removing and cleaning the actuating
valve in the overdrive unit.  Sometimes a little metal filing
or other debris gets lodged in the valve, allowing enough 
pressure to build up to partially engage, resulting in slipping.
You can do this without removing the unit from the car.  Mine
is a D type, probably different from yours, but it should be
under a cap right on top of the overdrive unit.
