Where can i locate the serial number on the transmission on a Subaru?

Before you say VIN. The engine and transmission have been replaced. and all is well EXCEPT, the Transmission Control Module, (TCM) seems to be bad. I am told by the dealer that I need to get a replacement TCM for that specific year and model the engine and transmission were pulled from (apparently not a 06 Tribeca B9).
To determine this I need to find the serial number from the transmission itself.
It seems this type of engine and transmission was compatible with a variety of Subaru vehicles.
THe salvage yard I got the engine and transmission are not sure which particular vehicle it was pulled from.
So, serial number hunting I go. Any suggestions would be appreciated.

On the top left side of the transmission you should see a flat shiny spot, the trans serial code should be located there. You may be able to see it from top if you look below the brake master cylinder. Right by where the Trans dip stick is
