Helping my friend with a transmission leak. The transmission leaks around the passenfer side, front corner of the oil pan. We replaced the pan gasket did not solved the problem. After examing it more carefully, it appears the leak is coming under an electric plastic plug right above the pan at that corner. I think it is called "plug adapter" based on the parts diagram CD.

It appears the plastic plug is simply pressed into the transmission body. There is, well was, a plastic tab allow me to insert a flat screw driver and pry it off the transmission. I BROKE THE TAB!!. It is too tight. I hope this does not ewquire a special tool.

Can someone suggest how to get this electric plug removed/replaced?

CAREFUL!!! You need to rotate the locking ring counter-clockwise. This will pull the connector out of the plug. Once it's dis-connected you can loosen the 7mm screw and pull the plug out. If you twist the plug you'll probably bend the pins and ruin the valve body. Get a new plug so you can see what it looks like. It'll make the job easier. The whole job shouldn't take more than a few minutes.

I did disconnect the connector first.

Where is he 7 mm screw? I did not see it.

Inside the part of the connector that it still attached to the transmission, right smack in the center. Be prepared to catch ATF when you pull that unit out. You'll lose maybe a half a liter or so.
