Issue after battery reconnect

[ryan88g]

Not entirely sure the issue is related to it or not.....After I reconnect the battery, when driving, and I let up on the gas, I can hear a clunking noise. It sounds like a gear snapping into place. Occasionally the car feels like it's downshifting. My mechanic had no clue to the issue, and someone else thought something might need to be reset after a battery dissconnect. It seems to go away after driving for a week or so. Anyone else have this problem?

I replaced the battery in mine a while ago and no issues.

The "clunk" you are describing is probably just a little driveline slack and that could happen when you back off and hit the gas. You are hearing the rear universal "clunk". Not an issue if that is what it is.

Could be the transmission relearning the shift points.

I don't think that a simple battery disconnect would flash the ******, I think you have have a special system to do that.
