I have a 2002 Freelander. Im getting transmission fluid into my coolant reservoir
That means the trans cooler has failed. It's located in your radiator. So you need to replace the radiator and flush the lines of the trans fluid and add new coolant. Hope that coolant hasn't entered the trans, if it did, it will be a pink milkshake and all the clutches will be compromised. Then you have to flush the transmission fluid and hope the trans last you for awhile longer before a rebuild.
Ditto on what Tom stated if you want to keep it stock. What I would do is what more and more tranny rebuilders are requiring and that is too bypass the cooler in the radiator and install a separate cooler just for the tranny, Most parts stores carry them for just standard duty, or you can go all the way up and put on one that has a thermostatically controlled fan on it, but that costs.
