Hello, can y'all help me out on how to replace my transmission cooler lines? It's leaking it just started not super bad, but I can see fluid. Due to age it's about that time. Thanks

Hi,

Chances are you will need to lift the vehicle to be able to access and perform the process. Also, there should be quick connectors that can be a little of a pain simply because they are retained with a thin horseshoe-like retainer which is likely to fly off and is nearly impossible to see on the ground. LOL

Regardless, I attached the directions below for the process. Take a look through them and let me know if it helps or if you have questions.

Take care,

Joe
