We use propylene glycol antifreeze will this harm the transmission? We flushed the transmission.

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.

In this model there is a cooling system inside of the radiator for thr transmission. If you get a leak in either one the coolents will then mix. Change radiator and have your ststems flushed several times.

You're right. Most cars are built this way. But the question is will the wrong coolant hurt the transmission. Any coolant in the transmission is bad, but the transmission will not be damaged simply from what is used for engine coolant.
