Automatic Transmission Torque Converter problems of the 2011 Honda Odyssey

Nov of 2016 took my 2011 Honda Odyssey into the dealership for a shudder between 40-45 mph. Service tech stated that the transmission fluid needs to be drained per Honda procedure. Fluids were drained and shudder stopped. May 2018 took back to the dealership same problem as before in 2016 at this time serivce tech states that my front brake caliper, left front drive shaft need replacing. Those items were replaced. Then oct 2019 back at the same dealership again with the shudder at 40-45 mph. The serice tech now states that my transmission fluid needs to be changed again per Honda procedure that its dark and dirty. After looking at transmission fluid its not dark or dirty. Still transparent and no burnt smell of bad fluid. After researching these year model vans are big on torque converter problems. Service tech perfomed a snap shot and verifired torque converter judder but are not wanting to fix the problem. Software has been updated and still having same issue with shudder. Honda declines to accept the issue.
