How's the oil level in the transmission?

Hi Guys,
 I have a perplexing problem with my overdrive. It is in good condition with
upgraded clutch, accumulator etc. It engages quickly but after a few minutes
of driving it starts to jump in and out of overdrive. I don't have a
throttle
switch fitted. My only suspect it the solenoid. Since there are 2 windings,
one to engage the overdrive and one to keep it engaged, could it be that the
internal switch or winding fault is causing it to "drop out" and then the
stronger winding immediately re-engages the overdrive? Opinions?

 2nd question is the replacement solenoid. There seems to be a wide variety
of
prices for this part from all the usual suppliers. Are solenoids all the
same?
Can anybody recommend which to buy or which to avoid?

 Thanks as always,
Piet
