I just had a lot of work done on my 2006 ford 500.
I had to replace my valve gasket and changed the spark plugs, as well as, the intake gaskets. Added new serpentine belt, flue filter and replaced a broken mount. The car seems to drive great and I am not sure if I am just going crazy or if there is another concern.

For one, I notice that my car is louder than before while driving and on start up. Also, it seems my transmission is shifting down way harder than normal. I defiantly notice and hear a difference when I accelerate and my rpm goes up, than I can hear the down shift. When I go down hill and I am not breaking I can hear a sound almost like something is spinning fast. Same when I come to a stop, something still seems to spin or run for a second and than catches up to the stop.

It's almost like my transmission is not communicating correctly with the electronic system. I say that because for a short time I had to drive my car with the ABS system turned off and it did the same sounds. Once the ABS was fixed it went away.

Not sure if it has to do with the work I have gotten done and somehow the electronic system did not calibrated correctly or if there is another concern.

I would appreciated any insight into this.

Thanks

 

You might ask the place that did the work if they can hear the sounds. Possibly something shifted or maybe the replacement mount is different from the original that came with the car. There may be something additional that they didn't see at the time.
