Are you saying you put this in the transmission? Ethylene glycol is the proper antifreeze for the engine. It contains additives to neutralize the acids that naturally form in the coolant. Those additives prevent corrosion of the heater core, radiator, and other metal parts. Ethylene glycol also contains a water pump lubricant additive.
What you put in the radiator has nothing to do with the transmission.
