Anyone have any advise on what to look into??

Would this be something sensor related or mechanical?
maybe dropping the transaxle pan for a new filter and fresh atf?

I haven't owned many automatics.. but I stall em like its a 5 speed manual

Is there a computer that controls the transmission? a sensor that mite need to be replaced?

thanks (in advance)

No electronic controls on the trans except the TC. Check for vacuum leaks.
