Put my car on and oil started to leak. I found the leak, just not sure what it is. I’m looking at and if it’s something I can replace. Driver side of car.

Hi,

That is a transmission cooling line. Based on where you live, it may have rusted. On some models, there is a quick connector that secures the steel line to the radiator. It has an O-ring that may have failed. Other connectors simply bolt on to the radiator. I attached a pic below.

Inspect the location to see if it appears to be the same as the picture I attached below. If it is, see if it may have come loose or if the steel line has rusted. You will need to do this from under the vehicle.

Note: I do not recommend driving it this way. Low transmission fluid is likely to cause internal transmission damage. Once it is repaired, make sure the level is full. Here is a link you may find helpful.

Let me know what you find.

Take care,

Joe
