The transmission has no coolant running through it. There is a heat exchanger inside the radiator for the transmission oil. If you have coolant in the transmission, you have bigger problems.

Most likely you have a failed head gasket causing coolant to drip down the back of the engine, OR you have a failed heater core causing coolant to drip out the HVAC drain which will puddle under the transmission.
