TF A904 reverse issue - band adjustment

OK, I drove the car to dinner last night and then first thing this morning. Reverse engaged about 90% so I backed out of the driveway and proceeded down the street. It shifts fine through the gears with no flare between 1 and 2 or 2 and 3.

I have never experienced the converter draining back in to the trans and causing this type of problem on any other car I've owned. I guess dropping the pan and adjusting the rear band is then next step. We'll see what happens.

Thank you for your replies, I was hoping for someone having this same issue and the band adjustment was the remedy.
