At the rear top of this trans is a small plug. It looks like a fill plug about 1/4" pipe thread.It is on the top, above the area where the speedometer cable conects. I first thought it was a vent, but it isn,t. I drained and flushed the trans, but found no corrisponding drain plug for this section. Any one know what it is about? Thanks.
