DIY 2007 toyota sienna auto transmission fluid change

Did the job in an early morning last week end, 2007 sienna use Toyota world standard fluid, got 4 quart @ $32 at Toyota dealer+ crushing washer. Got 10mm hex socket, loosened the drain plug, let the dirty fluid drain for 30 minutes, clean the plug, add the new washer and screwed the plug back, tightened it at 36lb torque, add the same amount of fluid. Done

Will not recommend a flush. The dealer charge $200, and sometimes the flush will cause transmission failure. Will do 1 more drain and change in 500 miles to sort of flush effect.
