Kia Troubleshooting Questions? Ask a Mechanic
Hello, my name is Bobby. Thank you for the questions. I have a few questions for you before I can come up with a diagnosis. How many miles are on the vehicle? Does this problem occur more when cruising or on take off? Does it get worse or better as the engine warms up?
Thank you. Have you had the transmission fluid changed?
Thank you. There is obviously a problem. If the fluid is low then it went someplace. If there are not any external leaks then most of the time this is caused by an issue with the transmission oil cooler. It may be allowing transmission fluid to enter the cooling system. If there is no evidence of this then it is possible that someone may have accidentally drained it or not filled it properly. Have you ever had the transmission serviced?
