This is an interesting piece of information! I didn’t mention…the “check engine light” came on…which was the reason that I took it to the Volvo dealership…they said that the reason the light came on, is that the thermostat has been sticking, and that it needs to be replaced (to the tune of $235.00…also my “software” needs to be “updated”…another $163.00). I had not noticed the car overheating…but then again, I do well to look at my gas gauge… Since I did know that the transmission fluid is cooled by running through the radiator, I asked if this could have caused enough of a problem with the thermostat that this is what the software indicator “picked up”…in other words, I question if there is a real problem with the thermostat…the service manager just said, “that’s an interesting question”. I didn’t realize how “interesting” that possibility might be.
So…should I ask them to check the water in the radiator for transmission fluid?
Tell me about this “vent”…where does it vent to? Does excess transmission fluid actually drip out of the car through this vent?
