How can any trans fluid truly be lifetime?
Has anyone here serviced the dipstick-less sealed trans by dropping the fluid in the pan and topping off?
If so, did you replace it with the Toyota WS ATF or go with an aftermarket product?
I had my 2011 tacoma replaced at 60k miles by RS offroad here in lakewood. I cant remember if they used Toyota WS or Amsoil. Either way, I felt, and they concurred, that there is no such thing as "lifetime" lubricant. I grew up in a house that took their lubricating fluids seriously; diff, trans, transfer, engine, coolant, etc. So i do it. Makes me feel good to change the trans, not sure if its needed or not.
