Summary of parts = engine and transmission

idk what tire kingdom is but I will guess most of their employees don't take as much pride in their work as you do in your car. I.e. They may not be the best place to bring it for repairs.

the engine may likely leak from several sources like the valve covers, intake, rear main seal and oil pan. If you clean the engine you may be able to then narrow down the source of the leak.

the trans could leak at the pan, the dipstick seal, or could be converter drain back that causes an overfull condition leading to leaking. Cleaning the trans and then inspecting may also give you some insight into the source of the leak.

if the leaks are just drips from being an old car as opposed to adding quarts of fluid a week I would just keep an old piece of cardboard under the car when parked this will prevent driveway/garage floor staining and save you plenty of aggravation.

Your going to have to do some detective work to determine where the fluid is coming from. Anyplacewith a machined surface with fluid and a gasket to contain it is a potential leak. You probably have several small leaks, I don’t think your going to find old iron of any kind that doesn’t mark it’s territory. The most likely culprits are valve covers, oil pan, timing cover, rear main seal, the trans could be oil pan, pump gasket and/or the o-ring, speedo housing, speedo cable seal, etc. One way to find out exactly where the oil is coming from is to add just a little of the fluorescent dye used to find leaks in A/C systems, add a little to the engine and trans. Take it for a long test drive, the dye will be easy to see with a black light. The dye is available at most parts stores for a few bucks.
