Hello. Heater failure and transmission issues are signaling that the cooling system is having a complete meltdown. Both of these systems depend on the cooling system to work correctly. Typically when the entire system is struggling there is a severe leak leading to a lack of fluid, a failed thermostat, a clog, or failed water pump causing a lack of circulation. The first step is to check the level of coolant in the radiator and overflow reservoir. If the level is low, then there is a leak or the engine is consuming the coolant. If the coolant is full, you will want to turn your attention to testing the water pump, thermostat, and possibly flushing out a clog. The only way to tell why the vehicle is overheating is to test each of these components individually.

From what you've described, this is due to a stuck thermostat most likely. This is why the radiator is not getting a warm flow of coolant. I'd suggest having this looked at by a certified technician, like one from YourMechanic....
