New to the Regal community and loving the car thus far. 2012, 2.4. 30K miles.
Reading through the transmission issues, mine sounds similar, but is more prominent from 2nd to 3rd....
There is a very noticeable "lag" when the car goes from 2nd to 3rd. It is not overly jerky, but you do feel the car hesitate to an extent and then catch. As soon as the car does hit 3rd however, there is a "surge" in power once it initially hits 3rd, almost as if it is making up for the lost time on the shift! Again, not that is is jerky, but it is "lagged"
Also, where in the heck is the dipstick to check the automatic tranny fluid??? There looks to be a cap it could be under off the the right hand side of the engine on top of the tranny, but was not sure if I should open?
