For the 403 the battery ground is attached to the engine at cylinder #1 and there is an engine ground strap attached to the fire wall.  I am not aware of any direct transmission ground.  Here is a diagram I created to help with a similar question.  Hope this helps.

There's a redundant ground from the transmission case lower bolt on the Driver's side into the engine block and runs across to the body near where the speedo cable bracket is.
