I believe the modulator valve is leaking because I have to add fluid. Where is the transmission modulator valve located on this car?

Hi,

They haven't used vacuum modulator valves for some time. Do you notice any leaks under the vehicle? The transmission does have supply and return cooling lines. See pic below. Check to see if there are any leaks there.

Let me know if you see anything that is wet with ATF, if there are no apparent leaks, when the engine is cold, inspect the engine coolant to see if there is evidence of it leaking into the cooling system.

Let me know what you find,

Joe
