Radiator, radiator cap, radiator hoses, water pump, coolant reservior and heater core are the more obvious areas. If you notice coolant in your oil it can be caused by a blown head gasket or damaged coolant sleeve in the head of the enging. If you cannot see any coolant leaks outside of the vehicle, check the floor mats on the interior. If you find coolant there, it more than likely is a heater core.
Because there are lines running from the radiator to the tranny, this lets the fluid flow through and be cooled so that it does not over heat in the tranny and cause damage to your bands inside your tranny.
A small radiator leak can cause antifreeze to leak on your 1998 Chevy Lumina when there are not any spots on the ground. A pinhole in a hose can also cause this.
Yes, a restricted or leaking radiator can cause the engine to overheat.
maybe your radiator is broken and you need to get a new one or just get a reparation if the radiator starts leaking when is in use it may be leaking because of the pressure of the water.
A leaking radiator hose would NOT cause this to happen, you have 2 problems with this vehicle.

Does it have 2 lines coming from the top of the oil filter, and going to the radiator. If so that is the oil cooler. You need to replace the RADIATOR Those 2 lines go into the radiator so it can cool the oil, and the tubes are leaking oil into the coolant.
If it is leaking trans fluid into the coolant it can cause overheating.
Running it while leaking can cause it to overheat repeatedly, which can cause thermostat damage , along with other problems.
most likely cause is your heater core leaking
A bad or incorrect radiator cap.
Worse case would be a blown head gasket. Running hot could cause this too. Best case is a bad radiator cap.
