help me plz

what is your take on this. It is the problem i am having
it runs hella bad and smokes and the oil temp is now running at 120. smokes bad. IT was 100% good till i put in more oil, same oil I have used for ever. comes in a brown jug, and i added 4 qt of tranny fluid to the tanny filler tubebecause it was low, stuff in the yellow bottles. Then all of a sudden it runs bad. I did spill some oil and a tiny amount of tranny fluid. Now the temp gauge for oil is higher. Before it was around 60-70 now 120. then when i start it the next morning it sounds fine. after i drive it for like 5 minutes a faint burnt oil smell is noticed. Then I starts to smoke and sound like a desiel engine
