91 300SE, Where's the converter drain?

Now another question. I am having a tough time getting any manual or C.D. on this car so please bear with these simple questions. Am trying to drain the torque converter on this car. Have rotated the converter 360 degrees and don't see any sign of a plug to drain it. Is it hard to see? Should I be looking up thru the converter grill or should I be looking horizontally thru the front opening to the converter? Looking up vertically there is a plastic dohickey about 3/4" in diameter on the converter grill. Does that have any thing to do with it? Thanks for your consideration. Milt.

You should be looking through the grill. It's just a small allen head bolt.

and also http://www.peachparts.com/Wikka/Trans7226Fluid

From my memory, I had to take out the ( black plastic) dust cover and use big screw driver to turn the engine. It's not that hard. Good luck

I went 15 years, even took the tranny out for rear main service once, and swore there was not a drain plug on this model.
However, there is, I finally found it. It's up on the back side of the converter about an inch up the curved surface. It looks just like the pan drain plug, uses a 5 or 6 mm allen. The plastic plug is just to hold the converter in the tranny during installation. The drain plug is not above the plastic plug, but rather about an inch farther back. So turn the front crank pulley bolt with a big socket (15/16 or 1 1/16, can't remember exactly) and look up behind the plastic plug (toward the rear) as the converter turns, and you will spot the drain plug.
Between that and the pan, you get almost all the fluid out, about 8 qts I think.

91 300 SE converter drain

Finally found it. Thanks for all your replies. The trick was to get my head to the rear of the cross member that runs under the converter. Then looking up past the crossmember at about a 45 degree angle there is an opening about 1 x 1 1/2 inches in the casting which surroundas the converter. Rotate the crankshaft and there is the plug in the converter. Milt.
