Most transmission pans, and metal differential covers don't come with drain plugs. There are companies that sell universal drain plugs which are good, but sometimes tend to leak if they get loose. They have multiple parts, and only have a small opening for the fluid to drain which makes it not the ideal choice if you want to drain your fluid rapidly. This article explains how to install a 1/2" X 20 magnetic drain plug into a 31/64" hole on a two wheel drive A4LD transmission pan.
To get started, there are two types of drain plugs, the regular size, and the oversize which is a little longer.
The black package on the left is the oversize type, and the red package on the right is the regular type.
These are the supplies which are needed to solder the 1/2" X 20 nut into the pan:
This is a two wheel drive A4LD transmission pan:
This is the pan lined up in a drill press before it was drilled. Take note of the mark where the bit is going to make the hole:
The bit is about to go into the pan. It's pressing against the pan:
The drill bit made the 31/64" hole in the pan:
The hole has to be cleaned with an abrasive pad:
The part of the nut which comes into contact with the pan has to be cleaned:
The inside of the pan has to primed with soldering flux paste:
The back of the 1/2" X 20 nut has to be primed with soldering flux paste:
Now it's time to solder the nut to the pan:
This is the inside of the pan with the bolt, and the nut removed. The picture has the magnetic drain plug installed:
This is the bottom of the pan with the drain plug installed:
