Has anyone had a similar experience?

2014 E63S Wagon 33K miles. When in sport or sport plus and coming to a stop the transmission will downshift to second instead of first. Happens perhaps two out of every five stops +/-. Everything else works fine. The dealer reflashed both the transmission and engine ECU and it worked fine for a week or so then back to old habits. Extended warranty expires early April so would like a permanent fix. If nothing else, it will go back to the dealer before then. Ideas?

Thanks

does this happen when the car is fully warmed up ? Because when cold it will not go into 1st until warm . Just a thought .

It doesn’t matter if it’s cold or warm, thanks.

Are you coming to a complete stop? If rolling, the computer and its algorithms may be trying to accommodate you driving style.

Full stop every time.
