Transmission failure and replacement (photos) ✨
Hey everyone,
Just wanted to share my experience and ongoing repairs on my 2015 Audi Q7 3.0T quattro S line Prestige with 136k miles. Hopefully this helps someone dealing with similar issues.
Issue: Transmission Failure
While driving, the transmission suddenly failed. Upon inspection, I noticed a leak coming from the transmission cooler line. After checking the fluid, it was extremely dark, burnt, and contaminated with clutch material — definite signs of internal failure. I am guessing over a year it leaked enough which is catastrophic to a transmission.Current Repairs (In Progress):
