So after a thorough diagnosis and a number of test drives, they were unable pinpoint the source of the trans failsafe warning. They checked fluids and internal components and all seems fine
However, there was an issue with the MAF so it was replaced. The MAF issue started with the stealer...they left the MAF loosely connected after service...

...I found out after a 4 hour trip to Boston, when i checked under the hood for a mysterious whistling sound. One of the MANY reasons i'll never return to the stealer unless i buy a new model. Anyhow, they performed a final test drive when dropping her off at my parking garage and still couldn't replicate the trans failsafe issue. They suggested i monitor and communicate any odd behaviors.
