I first need to know where the oil and water are mixing. Is this in the crank case or in the cooling system?

If it's in the crank case, you have a blown intake/head gasket. If it's in the cooling system, and you don't have a oil cooler, then that is transmission fluid, not oil mixing with the coolant.

This will happen when a crack develops inside the radiator (the radiator has a built-in tranny cooler as well).

You'll have to replace that.

the oil is mixing into the water and pusing the water out of the water bottle. the engine oil goes missing, i do understand the radiator can have an oil cooler but there is no pipes going to the radiator.

The radiator wouldn't have both a tranny cooler and oil cooler. If your oil is getting into the coolant, then it's either a blown head gasket, intake gasket or cracked block or head. (Despite the previous pressure test, there's no other way)

A pressure test will find it.
