Coolant leaking on bottom by transmission?

Hi,

If you are seeing it there, chances are it is coming from one of the heater hoses. They attach the firewall to the core.

Take a look through this link. It explains how to locate and repair a leak. Let me know if this helps. If you are still unable to find it, let me know.

Also, if you are not able to locate the leak, you may want to pressure test the system when it's cold. That will cause the leak to occur and give you a chance to locate it without dealing with a hot engine.

Here is a link that explains how it's done:

You will need a pressure gauge set, but most parts stores will lend one to you.

Let me know what you find.

Take care,

Joe
