Hello, I have a 2004 focus 2.0 dohc, recently the yellow warning lamp comes on, its for transaxle cooling. Weird thing is the light comes on and stays on for a bit soon after driving, don't see how the trans fluid could be over heating, after driving awhile it goes out. When the light is on the trans shifts harder then usual, when the light goes out it shifts fine. The car has 250 k on it, I recently got it and know by the service records it never had a trans fluid and filter change. Any suggestions would be great, I was gonna drop the pan and replace the filter and refill the fluid , I was not gonna do a flush as I heard it could cause more problems then help. Maybe something else is causing this, I wanted to see if I could get some advice before doing anything. Thank you I appreciate any help!!
