Where is the Overdrive Oil Drain Plug and Filter?

[hundredsixinsf]

I'm draining the oil from the gearbox on my '59 100-6 and my service manual states that there is a drain plug and filter on the overdrive unit and that the drain plug on the overdrive should be removed as well. Where exactly is the plug and filter on the overdrive and what does the plug look like?

Hi Hundred,
The plug is the large bronze disk (3" wide) on the bottom of the OD that unscrews. It kind of looks like a cog. The filter is a wire mesh basket inside.

Ah! found a picture in the shop manual. Section GGG2. Looks like there are 2 types of plugs.
