Hey scotty, my Dad's 2011 Avalon has the U660E transmission with no dipstick. The vehicle has 75'000miles and my Dad would like me to see if I can change the fluid in it. What would be the best plan of action for it. Could I drain the fluid cold and put the exact amount back in. The only way to check the level is to have the fluid temp between 104-113*F. It does not seem like it would be easy to check the level without knowing the temp of fluid. (My Actron does many things, just not that) Another option is to use the tools in T-SB-0036-13, but I am having a hard time finding a place I can purchase those tools from. I would like to know what you do with these transmissions and what your suggestions are. Thank you for all the helpful videos.

@AaronHicks , If it's a lifetime fluid, it means that it's designed to be used for the life of the car. Scotty is right most of the time, but to change a lifetime fluid, it shouldn't be done unless there's a leak or something.

The vehicle takes the WS fluid.

The owners manual shows no change interval. They claim it's lifetime, however Scotty once said " If your able, it is good to change it every 60,000

As always, confirm your owner's manual to see the intervals for changing the tranny fluid. Also, check what type of fluid the car uses. If it's a lifetime fluid, don't change it.
