Have been thinking lately it's making all the right noise when the engine revs up, but its just not putting the power down on the street like it used to. All bark no bite.

Can sometimes smell a slight burning smell after driving aggressively when getting out of the car (from underneath). I thought it might be a differential service bc I've never had that done, no huge difference after having the diff service done.

Could it be the trans? Feel like I had the AT fluid serviced recently enough. Anyone else experience this after several years of good performance? Ol' girl used to rip up the streets, now she's better served commuting and getting groceries.
