Once the plug is removed you will need an extension and a 7mm socket to remove the inner connector out of the transmission it takes a few turns to loosen the screw about 10ish if I remember correctly. Once the screw is loosened you can pull out the inner cap from the transmission. When reinstalling it just remember how you removed it as the plug has 3 groves that have to align to reinstall it correctly. Also use some transmission fluid to lube up the gaskets before reinstallation to stop leaks.
