Now should he fire it up in neutral or park to fill the converter ? I know you have to run it through the gears a few times but not sure what gear to start it in ?

Fill to the full mark, get warm and run through the gears and then check the fluid level and fill to the full mark. Clean it, if it's Dirty. Oil it, if it Squeaks. But: Don't fix it, if it Works!

I usually dump a quart in the convertor before sticking it on the trans so it's not dry on start up.

Put in Neutral and the fluid circulates filling the converter. Also the reason for the transmission fluid to be checked in neutral rather than park
