Q: Leaking transmission fluid and knocking

asked by on

My car is leaking transmission fluid and knocking.

If you are positive that your vehicle is leaking transmission fluid, the knocking sound is likely related. I would recommend having your vehicle inspected for leaks first. Once the leak source is determined, have it repaired by a qualified professional and have the fluid level topped off to specification. If your knocking sound still remains, you may have internal transmission damage.
