> this is the situation:
all forward gears work fine, reverse works ok when cold then quickly
begins slipping while warming up. if you've ever had a clutch disk
wear out and slip, that's exactly what this feels like, except it's a
new disk, t/o bearing, pressure plate, and flywheel.
this is a rebuilt, converted-to-o/d tranny. i'm using redline
mtl-90 oil in it. the o/d electrical functions have not yet been
energized. again i want to emphasize, all forward gears engage and
hold properly, warm or cold.
the shift lever seems to stay in place while in reverse and while
the gear slips the engine rpms run up just as you'd expect. how can
reverse work at first and begin to slip?
thanks for any/all advice or input.

Tom,
It sounds like the overdrive is building up operating pressure
counteracting the spring pressure on the overdrive clutch. Not enough
pressure to move the clutch but enough to allow it to slip.
The reason you don't see the same thing in the forward gears is because the
one way clutch is covering for the clutch.
You didn't say what type of overdrive you have. If it is a J type the
solenoid valve may be malfunctioning. If it is an A type check the
solenoid adjustment.
