Thanks, Bill -
I don't suspect low hydraulic pressure because the O/D engages immediately when
I select it. Other than the slipping under load, it is working fine. But of
course, a check of the pressure before tearing the O/D down would make sense.
I rebuilt the unit in 1993, with new accumulator, pistons, seals, bearings,
etc. and I have religiously kept the oil changed at least once a year (and
sometimes more, depending on the mileage). I didn't do anything to the cone
clutch during the rebuild because it didn't need it then.
The odometer recently turned over 110,000 miles since I've owned the car
(1984). It had 51K when I bought it, but the odo wasn't working, so it might
have been significantly more. I have had O/D selected during almost all of
those 110K miles.
