I hear you Jerry. I'm '73 so I've driven a few, but it's sure been a while. I've looked at all the gears in there and they all look perfect, so any debris will be all my fault, lol. I've got some Valvoline 80w-90 that specifically says it's for "non-synchronized transmissions". Question do I just put it in before I put the cover back on or do I have to put it in through what appears the fill plug at the back of the trans?
