The first 3 are all different systems apart from each other without any sort of connection.
4 and 5 is the same.
(There can also be a radiator in transmissions, but its more common on trucks)
1 is the axle usually the rear axle that connects the transmission shaft to the wheels, its a box shaped and has its own oil.
2 is the transmission, has its own oil.
3 is the the steering pump, has its own oil (when you turn the steering wheel, its easy to turn because of this system)
4 and 5 is the engine cooling system, contains water and coolant.
Wrong. A transaxle is the transmission unit for a front-wheel drive vehicle. A transmission converts power to a drive shaft which goes to the rear wheels, for a rear-wheel drive vehicle. What you are describing in your example for #1 is the differential.
