2015 Lexus ES 350 Transmission Service

DIYDave dares to try and follow the steps of ‪@TheCarCareNut‬ and perform 60,000 mile maintenance on the "sealed" transmision on his 2015 Lexus ES 350. Will he succeed, or will he destroy the transmision? Can what he learns apply to other Toyota tranmissions, like the Camry, Corolla, or Sienna?
Thanks to ‪@TheCarCareNut‬ for his great tutorial video!
