TOYOTA Camry TRANSMISSION PROBLEM SHUDDER BAD FAULTY TORQUE CONVERTER, WILL LUCAS FLUID WORK?

This is a serious issue with the 2012,13 & 14 Camry. Repair Cost at the dealer between $2,500 and $3,000. So This is not a reliable Transmission. I would stay away from this vehicle or don't expect the 300k miles out of this transmission. Toyota has refused to do a recall on this issue.
So in about 2 weeks my mechanic will change transmission fluid and add LUCAS fluid to see if that solves the SHUDDER issue. Let's hope it does.
UPDATE March 13, 2021. Today we changed the transmission fluid and added the Lucas fluid 24oz bottle. The result not as I expected it. The shudder remains and I believe in part because it also needs the software update as well which is also part of the problem. Well I tried, now the next step will be to have the torque converter replaced and the software update. On March 2021 I had the work done at a Toyota dealer for $2,350 and a life time warranty. It is working perfect now.
