1994 Isuzu Other

Hello. I have a 94 Isuzu Rodeo, V6 Automatic 4-wheel drive, w/172796 on the mileage. The issue is that it started to leak coolant from between the bell housing, I pulled the transmission and flywheel and found a very small hole at the top of the engine block where the trani connects, the fluid is leaking from this hole. I called the Isuzu shop in my local area and they had no idea that there was even such a hole and could not tell me if a freeze plug belonged there or not. Please help!

Im guessing that is a drain for the valley between the cylinder heads, under the intake manifold. Check the intake for leaks and for small coolant hoses at the rear of the engine
