When I take my foot off of the gas it feels like it drops a gear. I can feel it at around 50+. I don’t know if this has anything to do with but I just had my battery replaced and noticed it on the way home from the shop. The fluids are fine. THANKS
When the old battery was disconnected, it likely erased some of the adaptive memory from the onboard computer. Now, the car is “re-learning” your driving style, and it could take a few more start/run cycles for it to complete its learning curve.
My suggestion is to just drive it as you normally do. If the situation does not change within a few days, then you should have it scanned for trouble codes.
What kind of car are we talking about here??? Year, Make, Model, Engine size.
