I can't think of any failure mode in an OD that would only occur when
accelerating.? The pump and accumulator need to maintain a minimum
pressure of 350psi or so, so you'd expect a weak pump or leaky
accumulator to cause disengagement, or slow engagement, when slow or
decelerating.?? Throttle switch, relay and solenoid would most likely
fail randomly.? I'd replace one at at time--starting with the
switch--since it's the cheapest/easiest to replace--then go from there.?
I've had both a bad switch and relay cause random disengagement.? If
it's not the switch, the relay can be carefully opened-up and the points
filed, to prove it's the problem or not before replacing.
