Automatic Transmission Torque Converter problems of the 2019 Subaru Ascent

We took our 2019 Ascent in because we were hearing some weird noises coming from the front end roughly 5000 miles. Upon further inspection the Subaru dealership informed us that there was an issue with the steering rack. They asked us to allow them to order a new steering rack and they would call us and setup an appointment to change out the rack. On Saturday the Aug 17th we went on a drive with a technician to show him what we were feeling in the transmission. He drove it for probably 15 to 20 minutes, several different speeds. He too noticed some weird shift points. Also could hear the front end. We left it there and called them today (19th) to find out that it isn't the steering rack. It's the coil springs hitting something causing them to chip. The technician stated, we will get with them on a new updated part and you can probably come in and swap out cars until we get the parts in. Meaning, give back service vehicle for ours. I told him at that point that I have no issues with them keeping it to reassure it's safe for our family to be in. He said ok I appreciate it I'll be calling you tomorrow. They also said that they did a torque converter dial in and that the transmission should be back to normal. Hopefully all is well and it does in fact fix the weird shifting and hesitation at all speeds. Accelerating and decelerating.
