I am having a coolant leak under the car. Appears to be where the transmission and motor meet. Is there a freeze/expansion plug located there? I have searched all over the internet and can not locate a diagram.

Good afternoon,

There are two core plugs at the back of the engine. The transmission has to be removed to gain access.

These rarely fail, Usually, it is a hose or gasket that has failed.

Did you pressure test the system?
