What is the possible source of this leak?

This is right between bell housing and transmission (oil plug can be seen there). I cannot really determine whether the spot is engine oil or transmission fluid cause of all the dirt down there.

Clean the area up, with engine de-greaser & some rags should work ok.
Then place some cardboard below to try to determine which fluid it is firstly.

If your really determined/worried open up the inspection plate on the trans its what gives access to the fly wheel and torque converter.

Hey I didn't realize there was an inspection plate on the 42rle. Where would that be?

The leak is minor right now. There are no drops or anything just a wet spot. However, I'd like to check out on it and the inspection plate sounds like a really good option.

Its actually a lower support hat is essentially the lower half of the bell housing.

Just to make sure I got this right. The lower half of the bell housing is removable and acts as inspection plate?

Could use a white paper towel give it a wipe - help narrow down the fluid type

Yup, the lower half of the bell hosing is removable and also acts as the inspection plate.

Isnt it structural though? And you must do something specific when reinstalling it? Seems I remember reading about it in the FSM

It is definitely structural but I seem to remember just following the torque specs in the FSM when I put mine back on. Don't remember anything unusual.
