Question about Cars & Trucks
There is normally a cooler in the radiator that cools the oil for the transmission. If the new transmission has a problem and generated excessive temperature in the oil that would be transferred to the engine coolant and could cause it to over heat. I would have the radiator check for blocked cores and the cooling fans were working before I started on the transmission shop as if the radiator was borderline before, it would not handle the extra load from the transmission. If it checks out ok then I would be asking why the oil got so hot that it overheated the engine As a side suggestion after you have sorted out the problems ,it is always a good idea to consider a air cooled system for the transmission oil as it removes the extra heat going into the radiator.

sealers usually end up costing you more in the long term than the short term. these sealers react to heat and air. so you end up doing nothing more than plugging up you radiator, water passage ports, water pumps get damaged. causing more over heating problems than they solve. no i would go for what the shop gave you as a quote. that seems a pretty reasonable quote for the position you are in.

Sounds more like an ignition control or coolant flow problem. Or, a/c fan not coming on with a/c.
Getting the water pump question out of the way, the pump either works or not. If it leaks it will cause an overheat due to coolant loss on flat ground or grades...doesn't matter. If the pump bearing or seal is bad it will still pump, it will just be loose and noisy. Coolant flow through the radiator is also essential...I don't think you have a problem there because generally this happens with less maintained higher mile cars.
A bad map sensor can cause your problem because it changes both ignition timing and fuel mixture, either of which can cause very high temps in combustion chambers especially when under a load. Mass air flow sensor can also do this but usually will cause idle problems. If fan is not on with a/c if the remainder of your cooling system may be enough to maintain decent temp control but cannot do this under a load. A/C turned off removes some load and therefore allow you to get up hills. Operating marginally, you can be pushing some coolant out of the system at times without even knowing it.
Now, about your engine: These engines are in my opinion a very poor design to begin with. Even with the best maintenance and low miles, they don't handle temperatures well. at this point, I'd be concerned that after repeated overheats and near overheats, your head gaskets may have started to fail, even though they were not the cause of the problem.Keep that in mind.
Have the items I mentioned tested. If you finally have the problem solved I suggest you change the thermostat as well...Overheating makes them unreliable.

You didn't mention replacing your water pump....that is what it is if you have NOT replaced it.

Testimonial: "Yes, I have bought the tool and pump to replace and after it is fix, I will contact you Thank you Tasha"
It is best to be systematic about this. It could be either the water loss or the overheating which is the basic cause, either one could come first.
- there is a test for combustion gases in the water jacket, from a blown head gasket. This will very quickly cause overheating, and the excess pressure will blow the water out the overflow reservoir. If the car has already overheated and died, this is unfortunately quite likely
- the temperature sensor in the block may have failed. This will prevent the fans from running when the engine overheats, and you can see this. The fans are not driven by a belt. P68....
- the thermostat may have stuck closed. You will have to get it out and test it, but this is not difficult. See p328
- this model of Camry has a plastic top tank to the radiator, which eventually cracks. Look there carefully.
- it may be that a radiator hose has gone soft and closed up. Check they are allowing good coolant flow.
- it could be that in a car this age that the radiator has silted up and is not allowing coolant through. Disconnect the top and bottom radiator hoses, when cool, and run water through from a garden hose to get some idea about that.
