Hello!

I have an 07 Impala and it has roughly 189k on it. Recently it has developed an issue that only happens here and then. While accelerating it will sometimes have a sudden bog down within the gear. After this happens, the transmission starts shifting hard and continues doing so up until the vehicle is turned off. Once I turn it back on, it goes away and sometimes returns and other times does not. I'm looking for points to what this may be or what might be causing this. Any help is appreciated.
