I took my 2014 Civic to the shop for a transmission flush a few weeks ago, because it was slightly overdue and I had a trip coming up. Since then, the car has felt...different. It hasn't been making any noises or anything and its still responsive when I drive, but it feels like something is wrong. I have no idea what fluid the shop used, but I'm assuming it wasn't the OEM Honda stuff. Am I just being overly paranod, is my car just grumpy about the wrong fluid, or is this possibly a symptom of a transmission issue?
