I couldn't sleep....was thinking about having to fork out cash for a new car. I've been searching the forum, but can't find my specific issue. Here's the situation:
a6 s-line 2.7T
Outside temp - 80 or higher (Texas summers)
Engine temp - warm (driving for at least an hour)
Sitting at a stop light, with traffic around
Upon accelerating, it shifts VERY hard from 2nd to 3rd gear. It feels like it like it slips, then it clunks into 3rd very hard. It's not a good feeling.
I've spent 4k on my car in the last 12 months, and I'm close to running out of patience.
Based on the forum, changing the trans fluid looks like the first step. What's the likelihood this will address the issue?
Also, if this doesn't address the issue, what's next?
