That don't bother me (much). As I plan on putting a B&M Transkit in it. So my question is. Do you think that the oil could have damaged anything such as the valve body?

People have been doing that for years. Automatic trans fluid is essentially a high detergent low viscosity (thin) oil. As long as you don't run the engine hard while the auto trans fluid is in the oil, it's really not much different than having an engine cleaner added to the oil. Either way you don't leave it in there for an extended period. Kayse can't keep up at all now. lol

There are a number of friction modifiers blended into transmission fluid that engine oil does not have so I would be leary of using a full load of engine oil in the trans. Maybe a pint or two for topping up in an emergency but not a complete fill. Can't say if the lack of those modifiers would make the trans more likely to slip or grab, but if this really was engine oil, I would suggest pulling it down and have a look while it's out of the vehicle.

At some of the class's they stated that when putting a valve body and other parts to use 30 wt and gear oil mixed 50-50 as an assembly lube

Most of the larger trucks that had Allison transmissions in them, used 10 Wt (Hydraulic oil). Never had any major failure that I can remember because of the fluid. I know it's not engine oil, but it's along the same lines with different characteristics. A True Hybrid: Burns Gas AND Rubber!

I have dont this also, I drove 275K miles in my old chevy Z24, and towed a boat during most of its life.. but if yopu trans has black oil in it, it maybe burnt trans fluid..

But in the morning I plan to take it out and hose the inside down with brake cleaner. If it's burnt atf I should see some nice pretty blue metal in there. I was thinking when I seen that that it might have been done to solve a problem. Like how they used to add sawdust to the atf.

Tranny fluid is a poor lubricant and the motor oil helps lube the bushings. Free advice and worth every penny... Factory trained Slinky rewinder.........
