Is it my Imagination?

[Ross]

Had my 30K service done--oil, tranny service, coolant flush and replace, fuel filter replaced. Since then (about a week and a half ago), it seems like my transmission is shifting more softly, like it did at first before I put a chip in. Maybe it's just my imagination? I checked the tranny fluid and it's at the proper level. Car drives fine, just seems like the shifting isn't as firm as it was. Am I crazy? OK, I'm crazy, but is there still something that could have changed the shifting after the tranny service?

The only 2 things I can think of are:

1.They didn't use Mercon V...

or

2. They reflashed your ECM...but I would think you would have noticed other issues if this were the case...
