I am NOT an auto mechanic in any way. At least not with newer vehicles. My love affair with the automobile was over a long time ago. lol I can only share some basics of what it DOESN’T sound like to me.

If it is in fact engine coolant, draining from the trannie bell, it seems unlikely it is a radiator issue, which is (was) located at the opposite end of the engine and only connected by hoses. I assume the radiator coolant level has been dropping in relationship to the leak.

Head gaskets seal between the combustion chamber and the outer edge of the block, normally on top. If the internal portion of the gasket is leaking into the cylinder, giant clouds of white smoke come from the tailpipe when the water base coolant is vaporized into steam, so that seems unlikely. An outside gasket leak would be noticed at the top of the block, not from the bell housing. It would be the same for an external block crack, even around the freeze plugs. Maybe a closer look at the outside is needed to see if it is running back and down to the place from which it is leaking.

An internal block leak that didn’t go into the cylinder above the piston ring level, would have to be going into the crankcase. Coolant will show up on the dipstick if that is the case, but would still have to get past the rear main seal and the leak would also contain signs of an oil leak.

Good luck and I hope Mr. SS finds something simple is the problem. I’m sure the romance of crawling around under a vehicle is over for him too.
